Push further and move faster with the Thermarest Parsec 20F/-6C mummy sleeping bag, bred for alpine starts and ultralight bivys. This bag is ultra compact to easily fit in your bag and is full of Thermarest's signature features.

Therm-a-Rest says:

Engineered for your fast and light adventures, the Parsec delivers lightweight and packable warmth. Just like an alpinist precisely selects his rack or a skier carefully chooses her line, we took the time to dial in the small details that create comfort and security in the mountains.

After you break camp, the mummy-style bag uses a compression sack to easily fit into your pack without weighing you down. Designed with high-quality materials and Therm-a-Rest performance features like SynergyLink™ Connectors, the Parsec easily handles three-season bivys and long pushes into the backcountry. Bottom line, those that need their sleeping bag to go further choose the Parsec. Storage sack and compression stuff sack included.

The Parsec 20 Down Sleeping Bag is part of Therm-a-Rest's 'Fast & Light' range, designed to keep you moving quickly in the hills making it ideal for alpinists and ultralight backpackers. 

Lighter and more packable than the Antares, the Parsec has all the Thermarest features you know and love at a fraction of the weight. It even features SynergyLink Connectors so you can integrate your mat and bag together, allowing you to move freely inside your bag without coming off your mat. This reduces heat loss, maximises efficiency and utilizes the warmth of your insulated mat.

800-fill down gives this bag superior temperature regulation and the Nikwax treatment repels any moisture that comes your way. There's a 60-40 down distribution, placing more down on top and less on the bottom where the down gets compressed. By placing the down where you need it most, this technology reduces the weight of the bag while increasing the overall warmth.

Overall an excellent bag that offers lightweight and packable warmth.

 All about down filling in sleeping bags
  • 800-fill Nikwax Hydrophobic Down: Dries 3 times faster than untreated down without using dangerous PFCs.
  • SynergyLink Connectors: Integrate the bag with a mattress for optimal comfort and efficiency; removable for versatility.
  • ThermaCapture Lining: Top of bag is lined to trap radiant body heat and retain warmth without adding bulk or weight.
  • Zoned Insulation: Maximizes warmth and saves weight by intentionally placing fill where you need it most. The Parsec places 60% of the fill on top and 40% on the bottom to give the bag an elite warmth-to-weight ratio.
  • Toe-asis Foot Warmer Pocket: Ergonomic toe box that rapidly warms cold feet in a pocket of warm down.
  • Quilt and Blanket Loops: Customize your sleep system by layering our quilts or tech blankets for increased warmth.
