Lamina 15F/-9C Sleeping Bag

Down is warmer for the weight, but it has one critical weakness: get it wet and it stops working. The Lamina 15 solves that problem with synthetic insulation that holds onto its warmth even in damp conditions, which makes it the right call for environments where moisture is a constant. Guides have leaned on it for client use throughout full seasons and it keeps performing, packing down smaller and lighter than you might expect for a bag rated to 15 degrees. It is not the ultralight choice, but reliability in wet conditions is worth the trade.
