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!

Rain/Wind Pants RS001 Review

by - verified purchaser
Very nice seem to be well made heavy material and I also like the stirrups to hold the bottom of the legs down. For the price you can't go wrong way better than a lot of others that I've seen for way more money. Over all I am very satisfied thanks a lot Jafrum again very sturdy should last for a long time.

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.

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.

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

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.

Rain Pants RS001

by - verified purchaser
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

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

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,

A shopper on Nov 7, 2015
Best Answer:We saw those pics too, but our rain pants did not come with suspenders. Still great pants for riding in the rain!

My husband is 6'3. The last pair of rain pants rode up and his boots got soaked. How long are these pants?
Mary S on Nov 3, 2015
Best Answer:They have straps that go under the foot that prevent the pants from riding up.
