Dial in your existing layering systems or invent an entirely new one with the compressible, featherlight Nano-Air® Ultralight Pullover. This stretchy and ultrapackable insulated layer is built for cool, high-output days when you need breathability and just a touch of warmth to stay in your sweet spot for longer. Made in a Fair Trade Certified™ factory.

Features:

• Shell and lining fabric is made from 100% recycled polyester ripstop with mechanical stretch, exceptional breathability and improved abrasion resistance, and treated with a durable water repellent (DWR) finish made without intentionally added PFAS to shed light moisture
• Light, breathable and stretchy 20-g FullRange® insulation provides featherlight warmth through the shoulders, outer arms, and front and back body; uninsulated underarm panels vent heat and reduce bulk
• Slim fit is built for comfort under a harness and a backpack, and articulated patterning provides exceptional range of motion
• Deep, two-way, center-front zipper allows venting, with a smooth, low-profile zipper garage for next-to-skin comfort
• Low-profile, generously sized, vertically zippered chest pocket keeps essentials warm and close at hand; pullover easily self-stuffs into it, with a carabiner clip-in loop
• Stretchy, soft, moisture-wicking and quick-drying Capilene® Cool Lightweight fabric at the lower arms adds extra stretch to push the sleeves up the forearms
• Made in a Fair Trade Certified™ factory, which means the people who made this product earned a premium for their labor
