Insulation:
- The sleeping bag features high-quality 800-fill Nikwax hydrophobic down insulation. This not only ensures superior warmth but also repels moisture, a crucial factor in damp winter conditions.
Weight and Packability:
- Weighing in at just under 3 lbs (<1.4 kg), the Therm-A-Rest Parsec is surprisingly lightweight for a winter sleeping bag. Its compressibility is noteworthy, easily fitting into a compact stuff sack, making it an ideal companion for backpackers who prioritize space efficiency.
Shell and Liner Materials:
- The outer shell is constructed of an ultra-light 20D nylon with a durable water repellent (DWR) finish, offering protection against moisture and abrasion. The soft and breathable 20D nylon lining enhances overall comfort while keeping the weight down.

Field Tested:
During my winter camping expedition to Madawaska Provincial Park, where temperatures plummeted to a bone-chilling -18°C, the Therm-A-Rest Parsec truly shone. The bag’s insulation provided an exceptional level of warmth, keeping me cozy and comfortable throughout the night. Despite the harsh conditions, the Parsec™ maintained its loft, and the draft collar effectively sealed in heat, preventing cold spots.
The hydrophobic down insulation proved invaluable when condensation built up inside the tent. Unlike traditional down, the Parsec™ resisted moisture, ensuring that even if the outer shell encountered wet conditions, the insulating power remained uncompromised.
The mummy shape contributed to the bag’s overall efficiency, providing a snug fit without feeling restrictive. The zipper, featuring an anti-snag design, operated smoothly, allowing for easy ventilation when needed. Best of all, the additional insulation in the Toe-asis zone ensured that my feet remained “Toe-sty” all night long.
