The Mountain Hardwear Women's Laminina Z Torch 0 Degree Synthetic Sleeping Bag delivers women-specific warmth for winter camping in a synthetic package with lightweight compressibility that rivals the performance of down. Lamina welded construction anchors continuous insulation to a seamless, water-resistant shell fabric, and it allows the insulation to be selectively zoned to maximize warmth where you need it most while reducing weight and bulk in other areas. The result is a bag that insulates more efficiently while saving weight and packing down smaller. This women's model also packs more insulation than men's bags since women have been proven to sleep at colder temperatures than their male counterparts. Lamina Revamp Ripstop fabric offers lightweight durability and water-resistance. Thermal. Q insulation is highly compressible and maintains excellent loft, which, when combined with Lamina construction, rivals the performance of down. And unlike down, Thermal. Q will continue to insulate even if it gets wet. A slight wider mummy cut allows you wear layers to bed when it's truly frigid outside. The comfort footbox lets your feet rest in a natural position, and the full-length zipper sports double sliders for adjustable ventilation. If you're planning on camping when snow blankets the ground, make sure you have the Lamina Z Blaze on your side.
