Wondrously warm layering.

The Sugoi Men's RS Core Long-Sleeve Base Layer is your first line of defense against winter weather and inclement shoulder-season conditions. Slip this low-profile base layer under your favorite thermal jacket, long-sleeve jersey, or wind vest for enhanced thermo-regulation during cool to downright cold conditions. Its Dri Active Core fabric actively wicks moisture off your skin for a dry, pleasantly warm feel. Moreover, you'll find flat seams for increased comfort and abrasion resistance.
