In fully cold conditions, the last thing you want to be is half-warm. Don't leave your lower body out in the cold - wrap it in stretchy, breathable warmth with our new Nano-Air Pants. They use the same 60-g FullRange warm-when-wet synthetic insulation (now 40% recycled) as the rest of the Nano-Air family, offering great, soft comfort with plenty of breathability so any excess heat can escape. Incredibly comfortable and versatile, they're pants you'll be tempted to wear whenever the temperature drops even a little. The smooth, stretch waistband pulls on easily and won't interfere with shell pants or bibs, a harness or a pack. A tapered leg with super-stretchy cuffs can be worn at the ankle or pulled up over your lower leg (no constriction) to fit under the top of a ski boot. The cuffs will even stretch over the top of an alpine boot. Fair Trade Certified sewn.
