Mountain Hardwear Lamina Z Torch 5/-15 Long Sleeping Bag



Item #: 332014103

Thermally mapped insulation and half-length center zip maximize efficiency. 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.
