The Nikwax hydrophobic treatment is not just practical - it’s also good for the environment with its water-based formula that’s fluorocarbon-free. How did Therm-a-Rest make its sleeping bags as warm as they are light? The answer lies in the company’s proprietary ThermaCapture lining, which is an extremely lightweight reflective coating applied to the backside of the inner lining of the sleeping bag. It boosts warmth by reflecting radiant body heat back to your body with no added weight or bulk. The Parsec 20 comes with both a storage sack and compression sack.Ī multipurpose mummy bag needs to fit the body snugly but not too tightly, and provide for just enough warmth in all the right places. Therm-a-Rest achieves this with zoned insulation, which maximizes warmth and saves weight by intentionally placing the down fill where you need it most. Sixty percent of the fill is incorporated into the top half of the bag, where the body tends to feel the coldest, and forty percent into the bottom half.
