Therm-a-Rest Polar Ranger Minus 20-Degree Expedition Sleeping Bag
Polar expeditions and alpine adventures demand uncompromised warmth. The Therm-a-Rest Polar Ranger Sleeping Bag was designed with explorer Eric Larsen to ensure it was maximized for warmth even in Arctic cold settings. Certified by the Responsible Down Standard, the sleeping bag’s 800-fill Nikwax Hydrophobic Down repels moisture and stays warm in damp conditions, drying 3 times faster than untreated down without using dangerous PFCs. Connect the sleeping bag to a Therm-a-Rest camping mattress with SynergyLink connectors. Overlapping side vents open to allow arm use and customizable temperature control, and the Snorkel Hood controls frost created by breath and eliminates warmth-sapping cross drafts. The top of the Polar Ranger is lined with ThermaCapture Lining to trap radiant body heat and retain warmth without adding bulk or weight. Designed with Zoned Insulation, it maximizes warmth and saves weight by intentionally placing fill where you need it most.
Our founders’ mission was simple: create a better way to sleep outside; because when you rest better, you play better. Their ingenuity and vision back in 1972 led to the creation of the first self-inflating sleeping pad.
Today, we’re still working towards the same mission to craft the best sleeping pads and bags on the market. We’re not just giving explorers a better way to camp, we’re giving them better adventures tomorrow.
