When summer nights beckon, the Therm-a-Rest Parsec 32 ultralight sleeping bag delivers unmatched comfort and portability. Constructed from a soft, 20-denier recycled nylon, this sleeping bag is both durable and eco-friendly, certified by the Global Recycled Standard.
Featuring 800-fill-power Nikwax Hydrophobic Down™, it absorbs 90% less water and dries three times faster than untreated down, ensuring you stay warm and dry even in damp conditions. This down sleeping bag is also free from harmful PFCs and adheres to the Responsible Down Standard.
The refined shape and heat-mapped insulation enhance thermal efficiency by strategically placing down in key areas. A no-snag YKK® zipper simplifies entry and exit, while a cinchable hood and heat-trapping draft collar help retain warmth. The Down-lined Toe-asis™ foot pocket keeps your feet cozy, and the improved SynergyLink™ connector straps secure the bag to your sleeping pad, allowing you freedom of movement without losing heat.
Ideal for backpacking, the Parsec 32 has a tested lower limit of 32°F, making it a top choice for warmer temperatures. It even includes a compression sack for easy storage and transport. Whether you’re planning a summer hike or a spring outing, this is the best ultralight sleeping bag for summer adventures.
