Therm-a-Rest Parsec 32F/0C is a perfect sleeping bag for maximum comfort with minimum weight on alpine nights in summer and also in spring and autumn at lower altitudes. Filled with highly compressible 800lb Nikwax Hydrophobic Down™ that absorbs 90% less water and dries 3 times faster than untreated down, the Parsec will keep you warm and dry even in humid conditions. The ultra-lightweight GRS-certified 20D recycled nylon shell is a smart choice to save weight and the planet, while the new YKK® anti-crush zip prevents wear and tear with easy entry and exit. Improved SynergyLink™ connectors attach to the mattress to keep the sleeping bag in place, allowing freedom of movement and increasing thermal efficiency. The refined shape and thermal-mapped zoned insulation further increases efficiency by strategically distributing down in priority areas, while the down-lined Toe-asis™ foot pocket provides a place to warm cold feet.
