SEAMLESS REINVENTED
This is our softest and most comfortable base layer yet. We’ve worked with state-of-the-art seamless knitting technology to make a base layer that’s so comfortable on the skin that you’ll be amazed. But it’s also due to the new texturized polypropylene fibers that mechanically transport moisture away from the skin to the nylon layer where it’s transferred outward. Even the little details are just right like the ultra soft thumb loops that hold the sleeves in place and cover the wrist between your jacket and glove.

• Seamless construction for comfort
• Polyester/Lycra® for excellent wicking
• Thump-Loops
