A "Can't Do Without" Piece of Gear I swear by these things. We are in the Summer cycle here and it has been 80 + every day for almost 3 weeks now. The Tech Race bottoms and tops are comfortable, do an excellent job of whicking moisture away from you and help regulate your core temperature. They also make it a snap to take your outer gear on or off, especially leathers! I have enough of them to rotate as I ride every day, because I don't ride without 'em! Best to hand wash them and then just hang 'em up; they dry quickly, and if done this way they last longer. Keep them away from Velcro! DO this and you will be golden. July 31, 2013
Weird dimensions, NO FLY! Great to find long tights to be worn under leathers, and meant for hot temperature. But fit is strange, especially in area were legs meet groin, and THERE IS NO FLY! June 17, 2013
Great Product I purchased the matching top and it was excellent.(I left a review on that item also). I had originaly purchased the summer bottoms in Md/Lg which ended up being to small.Returned them for the summer race tech bottoms in Xl which have worked out great. I can't say much about how they will last but if you don't get to ruff with them taking them on and off I think they would last a good while.Everybody takes care of and treats their stuff differently.The change in wearing, and mostly getting in an out of my suit is great.It was muggy and 90 here today and the base/layer did great in my opinion. The description for the race tech summer base/layer is incorrect on here it list them as relax fit but they are a compression fit to help your muscles.I went to alpinestars web and got the correct info.I informed the person that I ordered from about the wrong info for the product but nothing has been changed as of yet.So check it out for yourself.I guess the guy I talked to didn't believe my info.I used the part numbers to get the correct description. Return was easy and money was returned to my card very quick. May 4, 2012
