Good cold weather bag.


  • Good warmth-to-weight ratio

I have the long version of this bag. It's very warm, the coldest I've had it was at 2°F, -17°C on a Therm-a-Rest Xtherm. I was very warm.

The interior pockets are a very nice addition, but as with all the Phantom bags, you'll be wrestling with a snagged zipper if you don't take the time to be careful with the zip.

I bought this sleeping bag a month ago and did Everest trek in it. Before using it i thought it was quite expensive but after using, my impression was totally changed. Now I have a confidence to sleep easily and warmly even in very low temperatures.

The only drawback I feel is a little greater volume and no inner zip handle. Overall very good.
