M's Nano-Air Light Jacket

The Nano-Air® Light Jacket was made to be worn for the entirety of your aerobic, start-stop mountain activities, so you’re never slowed down by having to change layers. Stretchy and breathable FullRange® insulation dumps excess heat when you’re working hard and keeps you warm when you’re not.

Features:

• Shell and lining fabric built from 100% recycled polyester ripstop is stretchy, breathable, abrasion resistant and comfortable next to skin, with a durable water repellent (DWR) finish made without intentionally added PFAS to resist light moisture
  
• 40-g FullRange® insulation is warm, stretchy and exceptionally air permeable; combined with the shell and lining, this provides excellent mobility and breathability
  
• Articulated patterning and strategically placed, low-profile quilting combined with stretchy fabric and insulation provide an exceptional range of motion for unhindered movement
  
• Center-front zipper has a zipper garage at the chin for next-to-skin comfort
  
• Two handwarmer pockets and one chest pocket are zippered, low profile and low bulk to wear comfortably with a harness or a pack; jacket self-stuffs into the left-chest pocket
  
• Sleek, low-bulk, snag-resistant cuffs allow stretch to keep warmth in and pull up over the forearms for visibility and temperature control; a cleanly finished hem seals in warmth
