Therm-A-Rest Parsec 0° Down Sleeping Bag (7° Test!)

I took it out in 7 degree temperatures with industry certified thermometers and tested it out! I would not recommend Thermarest Parsec 0° Down Sleeping Bag below 5 degrees after my usage and testing. It might work at 0 degrees, but I can confirm a good night in 5 degrees. With space to add a small insulation layer to extend the bag rating a little! The Therm-A-Rest Parsec 0° Down Sleeping Bag is comfy, well thought out and has even warmth! Here are the results!

From Therm-A-Rest:

"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."
