Very Effective

These are really nice. I agree with a previous review that they are a bit long in the rise, but nothing that can't be dealt with. I love that they're PVC lined and cuffed at the bottom. The pocket is handy too. Caution: Believe what the sizing chart says. I'm a size 8 woman and have never taken an XS in my life. I couldn't believe that I actually needed one this time. I ordered a small. They're a bit too big! Nothing I can't work around, but if I had to do it over I'd get the XS.

Happy to Review



Excellent rain pants

Comment: These are excellent rain pants for when you're out riding your motorcycle. They have zippers on the bottom as well as velcro, for a secure fit. Also, the big pocket on the outside is handy. The length of the pants were a bit longer than expected but, all in all, I am satisfied with the item. Especially at this price!

Great product

I had wanted a pair of rain pants that easily fit over my day clothes and these fit the bill perfectly. The only problem is that my shoes still get soaked. In addition to these pants I'd need to wear waterproof boots or waterproof shoes and socks (the cuffs are not long enough to sit in my shoes while my knees are bent). But for protecting my legs, these are great. They even come with a side pocket where I can put my keys, etc.

These pants are great

Comment: These pants are great. They are well made, but i must warn you they do run large for women. I ordered the XS and the waist was big. More important, however, I inquired about the length because I have a 28 inch inseam and I certainly didn't want anything very long. The service rep went so far as to go into the warehouse, take the pants off a rack, and measured the inseam for me. Now that's customer service. The XS' length was about 31 or 32 inches. Even though it's long, it does cover my boots adequately. Plus it's wind resistant. Very good buy for the price

These by far are the best rain gear

Comment: Been a rider for many years have had lots of rain gear, these by far are the best pants I have ever had. Good fit, look and feel like they should shed the dampness very well. Will let all of my riding buds know about them.


Upstate NY


Very satisfied

Comment: Pants came *quickly*. Very satisfied. And they are way better than I thought they'd be - I just thought they'd be some 'marginally thicker than a garbage bag' emergency pants. They are heavy, good quality pants that I'd wear on a daily commute. Very impressed.

Waterproof Pants

Comment: I had wanted something to wear over my day clothes when the weather is bad and these were perfect. They easily slip over my pants and keep them perfectly dry.

Comment: Perfect!!! Shipped quickly


Goffstown, NH

Rain Man

Comment: Well, I ordered these wonderfull rubbery things, and unfortunately I was concerned about the size, having read all the other comments. Well, I went smaller than I normally would've, and oops....they will sorta fit, but not too sure over the old chaps. I should have gone with my original size. Now, when I find some time I'll have to return and hopefully get the size ( XL) which I should have done as per the waist size of 42-48. Oh well, live and learn. :-)

Rain pants review

Comment: I was a bit septical at the onset and didn't want to spend alot of money but when the rain pants arrived I was taken aback with the quality and features. A far better rain pant then that I am replacing bought at HD for a quarter of the price!


Daytona Beach

Very good rain pants

Comment: I like that these pants come with a reinforcement in both the 'seat area' and the inside ankle area - close to the engine where it's very hot for nylon or other rain gear material. Very nice that they fit over boots, zip up and have the reflective velcro patch. Long enough as well that the legs don't creep up over your boots...these pants keep you completely dry. First rain pants I've had that covers everything. Very comfortable, too. Thanks so much for a great product, especially for the low price!

Perfect Rainpants!

Comment: We were very glad to see such good quality with our new rainpants. Yes, they are sized larger than the typical size - but that works for these especially! Great Product, shipping and price! Thanks!

Bernie & Karen


Fit well and work well

Comment: I am very pleased with these rain pants and they are a great buy for the money.

Dry Riding with Rainsuit

Comment: Pants are good quality for the price. Easy to put on with the quick rains we have.

Robert Herr


Worth it

Comment: I just used them and they fit great, they are big and long, I like it because you have more freedom of movement. I see rain pants as an objective need and at short periods of use. Also those protection pads they got are great. Usually I do not recommend much things, but these are.


Costa Rica


Comment: This is exactly what I needed. I keep them for emergencies so I haven't yet worn them but they do fit over my pants.



good rainpants

Comment: Haven't had to use them yet but the fit is great according to sizing chart. Got small with 36 inch waist and they fit perfectly.


East Aurora, NY

Rainsuit Keeps you Dry!!!

Comment: I read the previous comments and paid attention to what they said and ordered occordingly they fit fine and do a fantastic job of repelling rain and muddy puddles in the road.

Second Pair of Rainsuit

Comment: First pair are still in use. I have more than one bike and like to keep needed gear on board each for traveling. These have passed the test several times in driving rain.



Ultimate Cat

Comment: I bought rain pants. They don't let water in. What else can I say? You've earned a cookie for being a good Jafrum selling good waterproof pants. Just want to add that the workers in whatever country these pants came from must think we are a nation of giants as the size XS would fit LeBron James.


Lehighton, PA

RS001 Rain Pants

Comment: My order arrived in 3 days much to my surprise. When I opened them I was more than pleased with the quality and the fit. A real bonus were the snap on boot straps that prevent "ride-up". I would recommend this product to any one. They were pliable and packable in a small space. A lot of "bang for the buck"!

Great product, great price

Comment: After reading the reviews I felt I couldn't go wrong...and these are great. Good value for the price and I was surprised how well they're made. Had to exchange for a smaller size and the legs are still big, but doable. You won't be disappointed in these. Wore them in a deluge in SC and I was kept quite dry.

Numerous Rain Storms Tested

Comment: I recently took my bike on a 1800 mile trip and hit numerous rain storms, these held up great. I would highly recommend listening to the others about the sizing, they are absolutely correct!




Comment: Be careful ordering these as they run large. Seem to be adequate for the job and especially for the price.



WOW. Great Rain Pants

Comment: Just got my rain pants. WOW they are grea!!! Much heavier than I expected. At only $20.00 they are a real bargain. I could of used an XS but that was may fault. I haven't used them yet but am sure I will be dry.



High Quality Rain Pants

Comment: Got ky new rain pants and was amazed at the quality. I had a chance to ride in the rain and was completely dry. I should have ordered an XS but can deal with the small. LOVE THEM!!!



Rain Pants RS001

Comment: Looked all over for decent rain pants. Haven't used them yet, I assume they are waterproof...They do seems strong and durable, little extra lining by the pipes. I am 6ft, 195lbs not skinny but no belly either. Mediums seems to fit perfect over clothing. (I have a 36-38" waist, 32 inseam). Good product, great price, especially compared to the othr pants I've found on the internet and EBAY



Rainsuit Purchase

Comment: Good but a little short, maybe the length could be disclosed on the size chart, too. Really nice but the length should be disclosed.


DC area

Nice rain pants

Comment: These pants are excellent value for the price. The nylon in the seat is a really nice touch. I'm 6'1", 205 lb w/38" waist, and I ordered a Large - fit well, although the inseam could be a bit longer. No leaks riding in rain for the last 2 weeks.


Delta, BC

Rain Pants RS001

Comment: Very nice liked alot. I orderd the 1 piece rain suit as well and like it too but could only keed one or the other so i decided to replace our sets which were old and wearing out with the 1 piece RS5001 or i would of kept the pants. Great price



Rain Pants

Comment: My husband already had a jacket so just bought the pants. Have not had an occasion to use them yet, but very satisfied with the quality. Only wish is that length of leg and waist band had been included to make knowing size to purcahse easier.



Quality was surprising

Comment: These are fairly heavy and quality made


Carleton Mi

Great value

Comment: The description doesn't say much about the rainpants. Thunder Under, good quality nylon, elastic waste plus a drawstring. Pocket with hook / loop colsure. No slip area on rear seat, zipper and hook / loop closure on legs for easy on/off with boots. Removeable boot strap to prevent ride up and reflective strip on lower outside legs. Inside lower legs have heat protection for hot pipes. I am 5'8" and 195 wear 36 x 30 pants and a large fits quite well with a little wiggle room with chaps. These are not cheap, but rather inexpensive good quality rain gear. Jafrum does it again.


Crofton, Maryland

Work fine

Comment: I received the rain pants timely and tried them on. I didn't try the stirrups at the time, but I wish I had. When I pulled them out in a rainstorm, one of the stirrup snaps was broken. that leg kept riding up and my leg got wet. I called Customer Support and they shipped out a replacement right away. Kudos to the Jafrum team, but they should not have been shipped defective. My bad for not checking all snaps and zippers before I needed them.


Webster Wisconsin

great pants!

Comment: these pants are great, kept me dry all day. Run bigger though, I'm a larger but had to return for a med.

Motorcycle Rain Pants RS001 Review

Comment: These rain pants are easy to size and fit like you order them. I ride 40 miles one way to work and try to watch the weather for car days. It doen't always work out the way I plan so with these in my saddle bags I am as prepared as possible. Now I need to think about boot covers. Thank you Jafrum

Good pants but HUGE!!

Comment: I expected them to be a little big since I'm wear women's XS/Petite, but these seemed really, really big. I could fit in one leg big. I'm giving them 4 stars because they feel like pretty good quality pants for the price but they're definitely not for ladies on the short side who are a "small medium" or less.



Very Nice Pants

Comment: These pants are very nice and work well. I bought them for a touring trip through western Montana and southern Alberta / BC thinking that they would be disposable for the price. Not at all. The pants are good quality. We hit an extremely bad thunder system with very heavy rain and I never got wet. The sizing chart is correct. I wear 32 waist normally so I ordered xs. The pants fit over my gear with room to spare.


Coeur d'Alene, ID

They Failed On Me

Comment: I don't want to rain anyone's parade, or rain pants, but the first time I put on these pants, a snap broke on one of the boot straps. Nor were the heat-protection patches particularly well-positioned: I burned a hole in the leg the first time I wore them. The price was right. The product was not ready for prime time.

Replacement rain pants

Comment: Thicker material than my previous rain pants. Kept me dry while riding in heavy rain.



Excellent did what they should

Comment: Tired of riding to work looking like my blue jeans were died two different colors, I finally decided to purchase some rain gear. These pants came quickly, and as luck would have it it rained the next day. I have a one hour ride to work and they kept me perfectly dry the whole way. I have had to use them several times since. Take the advice and get once size up. I did that and mine fit perfectly.


North Carolina

Not bad for the price

Comment: I refuse to pay big bucks for rain gear. Usually, by the time I need it, I'm already soaked. I need cheap stuff to jam into my bags, just in case. These are really well built. The price was right. They fit my bill perfectly. As far as size, I wear a 34 waist, 31 inseam. I bought both Small and XS figuring I'd sent the other pair back. I'm keeping them both. The XS is pretty good for the most part, but the small is not too huge for me to use. This is just for you to judge your size. They're not bad.

These pants are perfect

Comment: I got these pants on sale not expecting much, but when I got them I was blown away. The quality was great, the length of the pants were long, and even had snaps that snapped around my boots. Killer pants for the price!


Grapevine, TX

Nice pants

Comment: Nice pants... great price


Cloudcroft, NM

Rain Pants @ Jafrum

Comment: Rain pants are absolutely waterproof. Very good quality. Wore them in a torrential steady downpour and they kept the rain out. Material does not breath and you sweat on the inside. Only one pocket on right back and you have to pull your rain pants down to get at your pockets on clothes underneath. These pants have an elastic waists band without a string to keep them tight. Tend to slide down and with the legs on the long side cause these pants to buldge in the calf area putting them at risk of touching bike hotspots. Bottom line is these are waterproof and do the job and I am glad I bought them. Would not hesitate to buy another pair at the price I paid.


Nanty Glo, PA

Excellent Product again. Thanks Jafrum!

Comment: Excellent rain pants for when you're out riding your motorcycle. They have zippers on the bottom as well as velcro, for a secure fit and you don't have to take off your boots to put the pants on. Non slip seat is great as well. In Florida where the weather changes frequently that is a plus! Thank you for another great product.

Nice Rain Pants

Comment: These rain pants are great. They slip on easily over your clothes and boots and are warm and waterproof. They are sized plenty big so believe the sizing chart!

Motorcycle Rain Pants RS001 Review

Comment: I haven't used them yet ...I bought them because other reviews were good. Construction seems fine I will update when I used them in the rain.



Motorcycle Rain Pants RS001 Review

Comment: The rain pants were a great value. Plenty of room to fit over clothes. Easy access for boots.



RS001 Rain Pants Review

Comment: Long time Jafrum shopper so it's no surprise to me that I'm pleased with these pants. Bought these to replace a pair that served me well, from Jafrum, of course. Definite rugged look and feel. Love the reinforced "rear" area and the heat resistant leg covers. Having the zippers and velcro at the leg bottoms will be a nice change for me. Seems to make it very quick and easy on/off. I went a size above what the chart said, but I like them a bit more roomy(36 waist, but went with a medium). They fit like I wanted. Ordered them Tuesday and here by Friday. Can't beat that. Also bought the boot covers and can't wait to try them out. I look at Jafrum first for anything I need. Come on rain.



Motorcycle Rain Pants RS001 Review

Comment: I ordered these because they have every option I would want in an expensive rain pant. I don't need these but couldn't NOT buy them because of the options and the price. I hope I never use them (like every rain item I own). Sorry that I can't give you a review on their wet weather performance. They fit correctly. I am 5'9" and have a 30" inseam, 36' waist (unfortunately) and the Large fits me correctly for a motorcycle rain pant. They went on reasonaby easily over my boots, which are normal lace up casual boots. They look very well made and I can't believe they can sell them for this price. You cannot get a better rain pant for any money IF they keep you dry. You will have to rely on others for that opinion. Shipping was fast and Jafrum has become my favourite mail order company.

Amazing value

Comment: Rode 500 miles through mist and scattered rain storms with these two days ago, and my leather riding pants stayed bone dry underneath. Fantastic rain gear and a must have. Even when I got caught in an intense downpour on the road, my legs were warm and dry. The boot straps keep them very secure and the legs are wide enough to take on and off over large boots.


Chautauqua, NY

Motorcycle Rain Pants RS001 Review

Comment: Best bargin yet! I have a ankle replace that limits my range of motion but with the ample side openings I had no problem putting on my rain pants. I rode for about 45 minutes in a hard rain and stayed dry. I would buy these again should I ever wear them out.

John Holmes

Better than expected.

Comment: I've worn thes twice and i love them. Very tight where they need to be and loose where they should be. Very nice!

price was great.

I choose these rain pants because of their features and cost. I have been very satisfied with my decision.

My waist is 42, is that about a med?
Eladio D on May 11, 2015
Best Answer: I' Sorry I don't know exactly. I have a 44-46 waist with the jeans etc. I got the 3x and they went over the pants and were comfortable when sitting or standing. I used them on a rainy day while riding an ATV 4 wheeler.

Remember they will need to go over your pants and you will need extra room. Im thinking you would need a large or extra large. If your in a hurry buy 2 different psizes and return the one that doesn't fit?

Good luck,
