Patagonia W Nano-Air Light Bottom
Unlike any midlayer bottoms you've ever worn, the Nano-Air® Light Bottoms blend the benefits of insulated tights and pants. They deliver warm, stretchy and breathable performance for moving fast in cold climates.
Light yet durable 100% recycled polyester ripstop shell and lining offer generous mechanical stretch and exceptional breathability, with a durable water repellent (DWR) finish made without perfluorinated chemicals (PFCs/PFAS) to shed moisture; warm and stretchy R1® Thermal side panels allow for crucial mobility
Revolutionary 40-g FullRange® insulation is warm and stretchy, and combined with the shell and lining, creates pants with excellent stretch and unprecedented air permeability
Slim-fit silhouette with stretch fleece on the side panels and calves to maximize mobility and warmth while reducing bulk
High-rise, stretch-knit waistband provides moisture management and comfort under a harness or a backpack
One right-thigh pocket with a low-profile invisible zipper stores small items securely while on the move
Cuffs feature quick-drying recycled nylon/spandex knit for enhanced stretch and movement, and push up easily to stretch over or tuck into alpine boots
