User Review: Marmot Hydrogen
Fill: 900 fill down
Temperature Rating: 30 degrees F
Weight: 1lb 5 oz
Price Paid: Retail
I got this bag because it was the lightest one I could find (1 lb 5 oz). I only ended up using it for 2 nights at Joshua Tree--after the second night I a small hole in the bag, and down feathers were leaking out. During the 2 nights I slept in it, I was surprised because I was a bit cold. I would estimate the temperature to be about 35 degrees, and I was also inside a tent with another person. I was only using 1 sleeping pad though. I returned the bag and have now upgraded to the Helium version, which is 8 ounces heavier (1 lb 13 oz) and does not pack as small as the Hydrogen.
