The Quantum Endurance 250 has been discontinued. If you're looking for something new, check out the best 3-season down sleeping bags for 2020.
Historic Range: $299.95
Rated as a 3-season bag, you'd expect it to perform prefect at +3. But no, I was freezing cold in the bag. The baffles just aren't filled with enough down to keep me warm. There are cold zones everywhere. Definitely not worth its money, unless you want to pay a fortune for a Pertex cover that contains only enough down to keep a duck warm.
Fill: 750 cuin (EU)
Temperature Rating: 0° acc. to manufator, +7 if you ask me.
Price Paid: 159 pounds
