Description:

The Mountain Hardwear Lamina +20°F sleeping bag features welded seams (as opposed to sewing) that don't pinch the insulation, maximizing loft, durability and warmth in freezing conditions. Lightweight Thermic Micro™ insulation is manufactured to produce a consistent, dense sheet of insulation that eliminates cold spots. Made from a combination of hollow and solid staple fibers, the fill has excellent loft retention, and is durable, soft and compressible. Slightly wide cut gives you extra room to move inside the bag; Comfort mummy cut efficiently maximizes warmth without constriction. Cozy ripstop nylon shell with a Durable Water Repellent finish sheds water; polyester taffeta lining breathes for comfort and feels great against skin. Welding stabilizes the fill without sewing through the bag, eliminating moisture penetration points and maximizing loft. Insulation is laid in a wave shape, enhancing loft and increasing thermal efficiency; offset welds increase stability and loft. Insulated draft tube isn't sewn through and extends to bottom of bag to eliminate cold spots. Face gasket and ergonomic draft collar seal out cold air. Full-length, 2-way zipper with locking slider is backed by wide, antisnag binding tape. Insulated zipper gusset seals in heat at base of zipper. Comfort footbox is shaped to allow feet to rest naturally; shape preserves loft and allows insulation to drape close to feet for more warmth. Interior zippered pocket at shoulder is great for stowing small necessities such as your watch or lip balm, alleviating fumbling in the middle of the night. Comes with nylon compression stuff sack and mesh storage bag.
