The Mountain Hardwear Lamina 30°F is an extremely warm, affordable and water-repellent synthetic sleeping bag, perfect for 3 season camping.
Utilising Mountain Hardwear's unique Lamina construction for impressive warmth to weight ratios, the Lamina 30°F/-1ºC is an excellent synthetic, water-repellant, camping sleeping bag offering. Through the use of Thermal.Q® insulation, the bag is both compressible and durable and was made for nights out in coldish damp climates or wet conditions. The Welded Lamina™ construction offers enhanced loft whilst eliminating cold spots. The soft polyester lining wicks away moisture and the lightweight nylon shell repels water. A full-length durable, anti-snag zipper has double sliders for ventilation.
What is Lamina Technology? Maximising and maintaining loft is the true measure of synthetic sleeping bag design. Over time, all synthetic bags gradually lose loft due to stuff sack compression and general wear and tear. Designing a synthetic sleeping bag that would retain loft – and warmth – over the long haul became Mountain Hardwear's engineering challenge, and their welded Lamina construction was born.
Why Weld? Welding stabilises fill without sewing through the bag and pinching the insulation, thereby maximising warmth and loft. Offset welds on the top and bottom of the bag increase fill stability.
