Columbia Men's Baselayer Heavyweight Tight with Fly

What’s next to your skin sets the stage for your comfort: don’t mess around. Developed with top physiologists, Columbia’s new heavyweight baselayers offer our highest warmth-to-weight ratio for optimal comfort in extreme winter conditions.

Ideal for trail running, snow camping or skiing in extreme cold, our bodymapped tights keep you warm and dry in all the right spots by placing Omni-Heat® reflective dots in zones that need warmth most, and Omni-Wick™ in high-perspiration zones for maximum moisture transmission. Antimicrobial treatment keeps the fabric feeling (and smelling) fresh during high-exertion activities, while the wicking waistband sits slightly below the waist to avoid unnecessary bulk. Highly stretchable, with flat-lock stitching and a gusset detail for enhanced range of motion, these heavyweight champions feature a built-in fly so you can answer quickly when nature calls.
