Nice Rain Pants

by - verified purchaser
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!

Excellent Product again. Thanks Jafrum!

by - verified purchaser
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.

Rain Pants @ Jafrum

by - verified purchaser
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.

These pants are perfect

by - verified purchaser
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!

Not bad for the price

by - verified purchaser
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.

Excellent did what they should

by - verified purchaser
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.

They Failed On Me

by - verified purchaser
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.

Very Nice Pants

by - verified purchaser
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.

Motorcycle Rain Pants RS001 Review

by - verified purchaser
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

Work fine

by - verified purchaser
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.

Great value

by - verified purchaser
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.

Nice rain pants

by - verified purchaser
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.

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

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,
