DESC: When stopping for the night at hostels or enjoying the reliably warm weather on a late spring backpacking trip in the Southwest, the Mountain Hardware Lamina 45 Sleeping Bag is all you need. Although it offers less insulation than other models, it's more comfortable in warm environments, packs down smaller, and weighs less too. The Lamina 45 includes all the heat retaining efficiencies found on other bags in the Lamina series, including the welded construction, insulated draft tube, face gasket, and ergonomic collar. - Sleeping Bags & Pads > Synthetic: 3 Season Sleeping Bags - Sleeping Bags & Pads > Synthetic: 3 Season Sleeping Bags
