Winner of the 2014 Gear Institute ‘Best New Gear’ Award, the Mountain Hardwear HyperLamina Sleeping Bag has been engineered to be the lightest and warmest synthetic bag on the market. Thermally mapped insulation and half-length center zip maximize efficiency, whilst Thermal.Q insulation offers industry leading warmth even in the harshest of environments. Ideal for multi day excursions in the bitter cold such as Alpine regions. 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 the Mountain Hardwear HyperLamina Spark concentrates 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. Perfect to shelter from extreme cold and wind, the HyperLamina Sleeping Bag features synthetic down encapsulated by a water resistant shell to allow you to hunker down for the night in relative comfort. A performance mummy shape with half zip allows superb functionality as it is snug, reduces girth, weight and bulk and maximises thermal efficiency. The performance cut also allows movement in the upper body whilst retaining heat in the lower extremities. The synthetic Thermal Q insulation is incredibly warm as it is designed to mimic the structure of goose down – rigid stems that form a matrix of gaps and softer fibers to fill those gaps. The result is a warmer synthetic whose structure gives it better compression rebound. It also allows the bag to be packed down into its own stuff sack for easy transportation. A 22D Dobby shell outer material allows protection from light precipitation
