Thermarest says
Whether on an overnight snowshoe, ski tour or just a quiet, off-season backpack, the Parsec 0F/-18C sleeping bag provides plenty of warmth for winter pursuits. Filled with highly compressible 800-fill Nikwax Hydrophobic Down™ that absorbs 90% less water and dries 3x faster than untreated down, the Parsec keeps you warm and dry in wet conditions. The ultralight 20-denier GRS-certified 100% recycled nylon shell is a smart choice for saving weight and the planet, while the new anti-snag YKK® zipper prevents wear and tear with easy entries and exits. Improved—and optional—SynergyLink™ Connectors strap to your sleeping pad to keep your sleeping bag in place to boost comfort and overall warmth efficiency. A refined shape shaves up to 2 oz off the previous version while adding a bit of girth in the shoulder to accommodate more clothing layers. Cold feet in the dead of winter? Not a chance, our down-lined Toe-asis™ foot pocket keeps your feet cozy all night long.
Our Verdict
The Parsec 0 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.
