DESC: For everything from summer climbing trips to fall camping excursions, the Mountain Hardware Lamina 20 Sleeping Bag is ideally suited for nights that are certain to get chilly, just not as cold as those encountered on winter backcountry ski trips. Rated to 20 F (-7 C), the bag features Thermic Micro fill, a soft, lofty, and durable synthetic insulation that stands out from the crowd because of its dense consistency yet amazing ability to compress for efficient packing. Welded Lamina construction, a patented process that attaches the shell to the insulation without sewing through the bag, maximizes loft and eliminates moisture penetration points. For a lighter synthetic fill alternative, be sure to consider the Mountain Hardware Ultralamina 15 Sleeping Bag. - Sleeping Bags & Pads > Synthetic: Winter Sleeping Bags - Sleeping Bags & Pads > Synthetic: Winter Sleeping Bags
