What Our Gearhead® Experts Are Saying:"This one-piece is my go-to base layer for deep winter days on the mountain. The Merino feels amazing, the drop seat is a smart touch, and I love not having gaps at the waist when I’m bending or layering."When cold days demand full-body defense, we reach for the Classic Thermal Merino Base Layer One Piece. This suit surrounds us in the comfort and performance of 100% Merino wool, bringing breathable warmth, moisture control, and odor resistance to every winter pursuit—from skintrack climbs to snowcat rides. Its slim fit follows our body for easy layering, while flatlock seams eliminate chafing under shell pants or bibs.
