Thermarest says

Designed to deliver maximum comfort while meeting high standards for lightweight packability, the award-winning Parsec 20F/-6C sleeping bag is the go-to choice when you need one bag to take you from early spring through late fall. Filled with highly compressible 800-fill Nikwax Hydrophobic Down™ that absorbs 90% less water and dries 3x faster than untreated down, the Parsec delivers superior performance in wet weather. The ultralight 20-denier GRS-certified recycled nylon shell saves weight, maintains durability and is eco-friendly, while the new no-snag YKK® zipper eases entries and exits and prevents accidental tears. Improved Synergy Link Connectors wrap around your sleeping pad to allow freedom of movement without shifting off the pad and losing warmth. The refined shape boosts efficiency even more, shaving up to 2 oz (57 g) off the previous version, while our down-lined Toe-asis™ foot pocket keeps your feet unquestionably warm. Whether this is your first bag or your next bag, the Parsec is ready to be your one and only.

Our Verdict

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. Roomier than Thermarest’s Hyperion range, if you value comfort it’s a great choice.

Light and packable, 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.
