RENO, NV (Sept. 30, 2025) — Therm-a-Rest® is set to enhance outdoor sleep experiences in spring 2026 with the introduction of its new Parsec™ Sleeping Bag and Corus™ Quilt. These latest additions are designed to provide superior comfort and warmth, featuring PFAS-free materials, 100% recycled nylon shells, and responsibly sourced Hydrophobic Down for optimal heat retention even in wet conditions.
Parsec Sleeping Bag: Best-in-Class Warmth-to-Weight Ratio for Mountain Adventures
The Parsec Sleeping Bag is crafted for adventurers seeking speed and efficiency in the mountains. For spring 2026, the Parsec series (available in 0F/-18C and 20F/-6C ratings) is upgraded with premium 900-fill Muscovy Hydrophobic Down, increasing its warmth without adding weight. Further updates include more plush baffles for improved loft, a refined internal zip pocket for easier access, and a simplified design that removes synergy straps for a cleaner aesthetic. Both options feature Box Baffled construction to eliminate cold spots and include quilt and blanket loops for system integration.
- Parsec 20F/-6C: weighs 805g (1 lb 12 oz) (regular)
- Parsec 0F/-18C: weighs 1,090g (2 lb 6 oz) (regular)
Corus Quilt: Redefining Backpacking Comfort
Designed for outdoor enthusiasts who value adaptable warmth and freedom of movement, the down Corus Quilt is a core member of the Backpacking Comfort category. Available in 20F/-6C and 32F/0C ratings and filled with 650-fill Nikwax Hydrophobic Down, the updated Corus is now entirely PFAS-free and comes in new colors. Its versatile design features a precisely shaped footbox that can slip over a sleeping pad for extra warmth, full-perimeter side baffles to eliminate drafts, and an exterior zip chest pocket for quick access to essentials. Like the Parsec, it also uses Box Baffled construction to maximize loft and eliminate cold spots.
- Corus 20F/-6C: weighs 735g (1 lb 10 oz) (regular)
- Corus 32F/0C: weighs 565g (1 lb 4 oz) (regular)
