Alpinestars Summer Tech Performance Underwear Boxers

The material used in this product is a VERY stretchy, lightweight cotton-like substance (although it’s a synthetic). When I pulled my size out of the package, my first reaction was “no way” since it was so small, but sure enough, it easily stretches to fit. Choose the size you would normally buy in men’s clothing. If you are between sizes, buy the larger.

This high performance underwear is used under leather, textile or mesh riding apparel for comfort in mild to hot weather. The material is super lightweight and is designed to wick moisture away from your body. It is “stretch to fit” type construction (see my fit comments above). High performance underwear like this can increase comfort, especially for those that do long distance riding with lots of hours in the saddle.
