Comments about The North Face Wasatch 40F Sythetic Sleeping Bag - Regular Size:

About the bag itself, it is rated at 40 degrees F.

I used it in Northern Minnesota in the Boundary Waters Canoe Area.

Nice bag, maybe should have gotten a large for more room.

The downside I found was the temperature at night was in the upper 40's and found the bag wasn't quite warm enough.

I should have gotten a 30 or 20 degree bag.

Whether it was just my body temp or the bag rating I am not sure. I assumed (not good) that it would be warm to 40 degrees and
then uncomfortable at a lower temp than that.

Otherwise the bag was nice. Zippers worked well, light weight, and folded up pretty compact for wilderness backpacking.
