Description of Mountain Hardwear Lamina 35° Long An excellent choice for damp, cool conditions. Welded layer construction maintains loft in the bag through repeated washings and compression cycles. The Mountain Hardwear Lamina 35 is a comfortable, roomy, mummy cut bag that is insulated with ThermicMicro™ fill. Thermic Micro insulation is an exclusive insulation developed for its loft, durability, softness and compressibility. 40D Nylon Ripstop is rugged, compressible and treated with a DWR finish for water repellancy. The face gasket and Ergo Draft Collar work together to seal in warmth. "The Lamina construction is simply the most technical way to make a synthetic sleeping bag. By welding the insulation instead of sewing, we eliminated the need for shingling. It’s a more efficient process that yields a more thermally efficient bag." – Chris Hilliard, Product Manager Experience warm and comfortable nights under the stars in the Mountain Hardwear Lamina 35.
