Comments about Regular
Big Agnes truly nailed it with this ultralight design. Weighing in at just 1.10 lbs, it keeps you warm even on those freezing nights, with a very extreme rating of down to 19°F. What's even better is how compact it packs down—about the size of a family-sized tub of cheeseballs (or, honestly, it might even fit in an empty tub!). It's especially great for me since I tend to overpack. Definitely worth the investment. I'm thrilled with it, and I love that it's made from recycled fabric with a silky smooth feel.
