good product but they run small I've worn these 2-3 times now in temps of the mid 80s under perf leather pants. They feel fine and certainly make it easier to get the pants off after a sweaty ride. They do run small. I'm 5'8", 30" inseam. Bought the M-L and they're just large enough. A bit short. Next time I'll get L-XL June 17, 2014
Great for summer riding & Track I bought these to wear under my leathers at the track and found that they are also great for wearing under jeans when out riding. Just like most Alpinestar gear it runs a bit small, I wear a 34 and got a large and it was still tight. Once I got out riding it wasn't that bad. I would buy these again but next time a size bigger.

Solid Product I wear these in the Summer. Definitely better than other brands I have tried that could not hold up to robust use. These base layer pants fit on the tight side and so far are holding up really well. I ride every day and rotate 2-3 pairs and have been for over a season now. I do hand-wash them, however, as I don't want to risk sending them through a machine. The material feels nice against your skin and feel very good under your suit. Keep them away from velcro! The minute they touch velcro you will hurt the material peeling them off! I do wish the elastic in the waist was a bit better, but over-all these are very good base layer pants for Summer use and I will be getting more when these eventually wear out. May 15, 2013
Tight !! I can wear medium, had to use X-Large. Very comfortable under leather suit. Tight !! I can wear medium, had to use X-Large. Very comfortable under leather suit. April 22, 2013
A better deal than the matching top While I didn't notice much advantage over a cotton t with the matching top, I definitely found these to be effective and better than some "Comfortech" lightweight longjohns I'd tried under leathers previously. And the price is better than the top, too. Still kinda pricey. They're nice, but not extraordinary. July 18, 2011
Good product for warm weather riders These are really good under leathers for warm/hot days. They breathe well and keep the knees of you pants from binding as the day goes on and you get sticky. The ultra light material is a bit more comfortable than the UnderArmour compression shorts I had been wearing. My only gripe is I'd like to see slightly more robust elastic in the waist - but it's a pretty hair splitting gripe May 10, 2010

RevZilla Store asked: Why did you choose this?
John S: Took a while to figure out size. Ended up ordering 4 different pair and returned the one's that didn't fit. Love these pants. They're tight at first but loosen up after time. May 18, 2014
Jeremy J: To wear under my alpinestar leathers Apr 6, 2014
Michael Q S: Big supporter of comfortable underwear to keep warm/cool, plus they have a front male opening (fly) which is really convenient as a couple of pairs (gifts) didn't have this simple feature previously. Saves getting half-undressed to just have a pee. Mar 31, 2014
