Fits well. Cool when you put it on Although this product is too expensive by 50%, it's a good product. I especially like the neck protection. Concerning fit, it stretches well beyond its initial size. It fits well. September 28, 2015
Great, Overpriced Base Layer The shirt performs as advertised, but does not seem to provide higher comfort levels than lower cost equivalents. The high collar helps eliminate irritation during extended rides. July 13, 2015
good base layer Joe Chirik recommended this product for my great Alaska adventure because the Rev'it Violet base layer was out of stock. It worked well and wicked away sweat. It was comfortable as well I prefer the Violet base layer because they accommodate ladies curves better. If you can't get those... These will certainly do the trick! October 7, 2014
Far too small even in xxl. I wear xxl in most stuff and do have compression wear for the winter, so I have a good Idea what snug fitting is like. This garment in the largest size possible wouldn't even let me get my chest into it. Nice fabric and all but a shame that that the xxl is just not big enough. August 4, 2014
Overpriced, wrong sized, not comfortable Have this thermal. Both long "summer" shirt and long pants. 1. They are super tight. If you decide to buy - buy at least 1 size bigger than yours. 2. I find material of my Rukka/Revit/Brubeck thermals MUCH, MUCH more comfortable and working better. I'm disappointed, wasted about 150 bucks for a piece of s.... nothing, piece of floor-cloth =D June 13, 2013
It really works to keep you cool under your full grain leather racing suits This product may be expensive, but it really works. It keeps your body cool while you're wearing your heavy leather gears. You can't compare this item with the under armor because this is made for racing gears and not sports equipment. Though they have similar functions, they serve different purposes and are designed with come rely different material and fabrics. After putting the shirt on I feel an immediate drop in body temperature. The difference is quite noticeable. While people feel that this shirt is same as the under armor. However this item is made in Italy whereas the under armor is made in third world countries. The compression fit of this item is great. It feels tight, but not uncomfortably so. You wouldn't feel queasy wearing this shirt after a heavy meal. An under armor will surely work, but this is more suitable for motorcycle application. I really recommend this product if you ride a lot in full leather gear in hot summer. July 28, 2012
Great way to beat the heat at the track! Purchased the Alpinestars Summer Tech Long Sleeve Top to beat the heat during my daily 80 mile commute and trackdays out here in the Mohave Desert. It's wickability and air flow were apparent as soon as I put it on. On the track this past weekend with temps over 90 degrees I was extremely comfy and was cool with leathers on or off. A must have as an efficient undergarment! Fit is some what small so order one size up from what you normally wear. May 8, 2012
100$?! ARE YOU SERIOUS?! This is basically an under armor rip off. They think they can charge 100$ just because it's "motorcycle" gear. Save yourself 70 dollars and go buy a long sleeve under armor warm weather shirt. Or if your looking for something to keep you warm underarmor makes cold weather shirts EXACTLY like this as well for around 40-50$. 100$---alpine I am ashamed of your greediness.
