Helium 15 comments

Ranked #508 - 25 to 5 Degree Down Bags
October 20, 2009
I purchased a Helium 15 degree for a September hike of the John Muir Trail. Night temps varied but lows in the high 20s at higher elevations. The bag was more than adequate and on a couple of the colder nights I swapped with my hiking partner who was sleeping cold in another top name 20 degree bag. I agree with some of the comments that suggested a neck draft collar would improve the bag. I also found that the zipper seemed inferior for this high end bag. It snagged easily and though it was also easy to free, having to do this multiple times to get the bag zipped was frustrating. Whatever weight was saved with this zipper was not worth the inconvenience. Marmot should fix this.
