The Mountain Hardwear Women's Laminina Z Spark 34 Sleeping Bag features unique Lamina construction that maximizes the loft of your insulation, eliminates cold spots and now comes thermally mapped to put insulation where you need it most!

By strategically placing insulation, Mountain Hardwear is able to concentrate extra warmth where women need it most – around their core and feet. The comfort mummy fit of the 34°F/1°C Women's Laminina Z Spark 34 bag offers room to move while remaining thermally efficient. It also features MHW's exclusive welded Lamina construction that maximizes loft and eliminates cold spots caused by traditional stitching.
