The Mountain Hardwear Hyper Lamina Spark is one of the best performing synthetic bags in its class, ideal for spring, summer and autumn. This sleeping bag is engineered to be the lightest and warmest synthetic bag on the market. Using heat mapping, different insulation weights are used throughout the top of the bag concentrating insulation where you need it most â€“ around your core and feet. Laminaâ„¢ construction welds the Thermal.QÂ® insulation to the shell and lining, eliminating the cold spots caused by traditional stitching. Thermal efficiency is optimized by a performance mummy-cut, face gasket and single centre half zip. All of which contribute to a warmer bag for less weight bring it close to the holy grail of weight, warmth and affordable price ratio.
