Patagonia says this is the most advanced base layer they've ever made. The Capilene Air Crew's unique fabric combines warm merino wool and soft polyester, and an innovative airblasting technology increases the yarn's loft while reducing weight. Seamless 3D construction eliminates chafe points and stretches to move with you. The result is a base layer with incredible warmth for its weight that wicks moisture, dries quickly and feels incredibly comfortable.
- Made of a blend of fine-gauge RSW-certified New Zealand merino wool and Capilene® recycled polyester for enhanced warmth balanced with improved wicking, durability and dry time
- Fabric is soft against skin and stretches to move with the body
- Seamless 3-D construction eliminates chafe points through the entire garment and has almost no wasted material
- Soft elastic knit cuffs and hem won't bag out over time
