The biggest source of heat loss in a hammock is underneath you, where insulation crushes flat against the fabric and stops working. The Snugpak Hammock Under Blanket WGTE fits externally beneath the hammock to create a separate insulated layer, blocking cold air and wind chill from below in a way a sleeping bag alone cannot. Filled with Snugpak's Travelsoft synthetic insulation, it stays packable and resilient in damp outdoor conditions, while elasticated adjustable guy ropes let you tension it correctly under most standard hammocks. A Paratex antibacterial inner lining manages odour on extended trips and the Micro Diamond outer is built for regular field use. It packs to 23 x 23cm at 1450g with the included compression stuff sack and pairs with the Snugpak Hammock Quilt WGTE for a complete insulation system. No fixed temperature rating is given, as performance varies with setup, conditions and layering. Finished in olive green.
