It's a bit funny trying on the Alpinestars Summer Tech Performance under-clothing, and writing about it...
A good rule of thumb with motorcycle clothing, a good kit should help rather than hinder, and the Alpinestars Summer Tech Performance under-clothing fits very well, no matter what I'm wearing over it or what type of motorcycle I'm riding, on of off road. That means helping me get in and out of my motorcycle suit when I'm hot, keeping me comfortable when I'm in my motorcycle leathers for long periods, actively helping me stay cool and dry when I'm riding my motorcycle.
The act is, the Alpinestar Summer Tech range of under-clothing is a versatile, comfortable, protective layer between me and whatever I'm wearing, however physical the riding gets. It stays comfortable without any of the ruffling-up you often get with more saggy undersuits (or a simple T-shirt). It's slippery, too, so getting tight leathers on and off is a lot easier. The 'compression fit' is supposed to support muscles and help prevent fatigue – although I'll be honest and say I have no scientific way of telling you if this is true or not. Of the various motorcycle undersuits I've owned, some have been good in certain conditions (dry and hot, cold and wet, damp and hot, etc..). While the Alpinestars Summer Tech Performance under-clothing tops on the side of being good in warm conditions the 'moisture-wicking technology' makes it more versatile, particularly when I'm riding hard because it prevents the dampness that thicker material like cotton causes.
There are various permutations of this anti-static, hypoallergenic and 60 percent lighter-than-cotton clothing in long-sleeve, short-sleeve, boxer shorts, vest and more which should suit most people's preferences. If yoo're interested checkout Alpinestars Summer Tech Performance Long-Sleeved Shirt
