  • Overview
  • It is rare to see sleeping bags with a synthetic filling with such satisfactory performance. The Lamina™ construction and Thermal.Q® insulation provide complete insulation and also prevent cold spots and draughts.

Product details

Thermally mapped insulation and half-length center zip maximize efficiency. Engineered to be one of the lightest and warmest synthetic bags on the market.

Lamina™ construction welds the Thermal.Q® insulation to the shell and lining, eliminating the cold spots caused by traditional stitching. By mapping different
insulation weights throughout the top of the bag we are able to concentrate warmth where you need it most – around your core and feet.
Thermal efficiency is optimized by a performance mummy-cut, face gasket and single center half zip.
