Rain Man

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

by - verified purchaser
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!

Very good rain pants

by - verified purchaser
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!

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!

Worth it

by - verified purchaser
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.

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.

Second Pair of Rainsuit

by - verified purchaser
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

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.

RS001 Rain Pants

by - verified purchaser
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

by - verified purchaser
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.

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,
