Warm nights in the alpine or shoulder-season camping at lower elevations call for a down bag that stays functional even when the weather doesn't cooperate, and the Therm-a-Rest Parsec 32°F/0°C delivers exactly that.

The fill is 800-fill Nikwax Hydrophobic Down, which absorbs 90% less water and dries three times faster than untreated down, a meaningful advantage for coastal and shoulder-season conditions across Canada where damp air is a constant. RDS certification confirms the down is sourced from humanely treated waterfowl. Heat-mapped Zoned Insulation distributes the fill strategically, concentrating it over your core and shoulders where warmth retention matters most and reducing it where your pad handles the work underneath. The down-lined Toe-asis foot pocket adds a dedicated warm zone for cold feet at the end of a long day on the trail or water.

The GRS-certified 100% recycled nylon shell and liner keep the weight down while making a smaller environmental footprint than virgin materials. SynergyLink Connectors strap the bag to your sleeping pad for a sleep system that stays aligned through the night without restricting movement. YKK anti-snag zippers and quilt loops for layering round out a well-considered feature set for a three-season ultralight down sleeping bag.
