Great Bag

  • Familiarity: I've put it through the wringer

I took this bag on the Tour Divide this year and it served me well. Had it below 30 degrees on a couple nights and it performed better than i thought even outside of the range. Overall a grweat bag that is very light and packs down fairly small.

Love this bag

  • Gender: Male
  • Familiarity: I've used it several times

Got this out for 4 days this past month and I'm thrilled with it. I upgraded from a 6 y/o Marmot Sawtooth so I'm basing my comparisons on that.
1. Its crazy light, and packs down pretty small. not 40F bag small, but small for a 30F bag
2. I love that with the bottom pad sleeve I get a boxer shape and the inability to roll off the bag for the same weight of a narrower bag with insulation on both sides
3. Big Agnes did a nice job of insulating the area around the zipper. The zipper is an inch above the seam with the sleeping pad sleeve and there is a draft tube that lays over the zipper and overlaps some with the insulation at the seam. Works to prevent the cold zone I've experienced over there.

a gripe:
the shell material is really thin; its held up to being stuck in the zipper a bunch of times, but might be a poor choice if you are hard on gear. I suspect anything in the Super Light category is the same.
