Alpinestars Summer Tech Race Top 3.7 5 3 3
It does what it's supposed to do. This item allows me to get into and out of my race suit much more easily. It's very comfortable and allows full mobility while on the motorcycle. Seems to breathe well. I think there are probably cheaper options out there that will do the same job, but I am still satisfied with the purchase. September 21, 2015
uncomfortable and big I am 5'8" and 160 lbs. The medium top fits well, but the pants are way too long and baggy. My biggest gripe is that the seams on the pants and top are sooo uncomfortable because of the nylon material used to stitch them together. Very scratchy. That being said, the top and pants are very breathable and allow me to get my leathers on and off with little trouble. I buy a lot of Alpinestars products but I would probably look elsewhere for a summer base layer. May 17, 2015
Functions as described Great Alpinestars product I'm more than likely commiting a major brand crossbreed. As I'm wearing this under my Joe Rocket suit. It's the first Alpinestars product for me and for sure isn't my last. I love this product it made wearing and getting my suit on and off a LOT better.It's like wearing a different suit.The feedom of movement in the suit is 100% better, and the cooling was great with my suits vents unzipped. I'm waiting for the matching bottoms to show up, as I'm sure they will be great too. I'll be leaving feed back on them as soon as I ride in them. As always the guys/gals did their best to help with sizing and fit. April 26, 2012

Phillip L: To wear under leather jacket in summer months to ensure comfort and protection. Sep 16, 2014
Zac M: Helps slide in and out of race suits better (well, I hope so!,) and it's nice to be wearing something underneath so I can unzip and slip out of the top of the suit in between sessions at the track. This should do the trick! May 23, 2014
Allen C asked: Hi, I was curious on how to order the size of this shirt. If I normally wear MD size T-shirts, does that mean that I should order a size LG? Is the material very small but stretchy? If I were to accidently order a size to big then is it forgiving to not feel uncomfortable while riding with a size to big? I'm assuming that the shirt will be tight but will have a good amount of stretch to it so that it fits the rider very snug. Jan 15, 2014
