Mountain Hardwear Lamina sleeping bags utilize welded construction and anchored synthetic insulation to provide consistent, targeted warmth, maximize durability, and minimize packed size and weight. The Women’s Lamina 30 Degree bag is ideal for backpacking or camping in warmer weather or moderate temperatures. The bag is insulated with lightweight, compressible Thermal. It utilizes 80% recycled content to reduce environmental impact and, unlike down fill, it retains its ability to insulate even if wet. A 30D ripstop nylon shell adds extra weather protection and a 40D polyester plain weave lining increases internal comfort. All fabrics are bluesign-approved. The bag has a thermally-efficient standard mummy cut that ensures warmth while helping to reduce excess bulk and weight. Proprietary, offset welded construction makes certain that insulation is properly distributed throughout the bag and eliminates any spots for warm air to escape, so you enjoy consistent warmth even after seasons on end of use. This construction also allows Mountain Hardwear to target additional insulation in key areas of gender-specific heat loss. Other features include an ergonomic insulated hood, an insulated draft collar, a contoured footbox, an anti-snag zipper, and an included storage sack. Both Right Zip and Left Zip options available. Both are brand new with tags. Brand new with tags, never used.
