Sizing Information

Alpinestars’ Thermal Tech gear is sold in alpha sizes. Select the size you would normally wear in men’s undergarments.

Our Two Cents

Thermal Tech gear is underwear that is designed for use as an under layer during cold weather. The material used in the Thermal Tech gear is a soft, but heavy duty, stretchable nylon material similar to common athletic apparel. It’s designed for a tight compression fit (so those of you that don’t like the compression fit, for example Under Armor, should consider another product). The tight fit is ideal for use under sport riding jackets and suits because it does not add bulk. This underwear would also work great for touring or commuting, and would be comfortable enough to wear all day if needed. It would also work great for other sports such as snow skiing.
