Alpinestars has come out with a line of "Winter Tech Performance" underwear that's designed for cold weather riding.

Full suits and separate tops-and-bottoms are available. The one-piece suit uses a hidden front zipper for full-coverage warmth with a minimal number of seams, and all pieces are made with dual density layers to provide good moisture removal.

Tubular, seamless construction helps ensure rider comfort, and polypropylene with elastine fabric that will not melt under abrasion add a safety factor.

The suit retails for $219.95 U.S., and the bottom is $99.95. Available in sizes from very small to very large, in black.
