User Review: Marmot Men's Helium
Fill: 900 fill down
Temperature Rating: 15
Price Paid: $340
I previously owned a Western Mountaineering Apache MF (microfiber) 15 degree bag and it did not perform as well as this bag. The Helium bag is warmer, even though it has quite a bit larger cut (roomier), and it weighs less. I can't think of anything bad to say about it. I would have given it five stars if the price was less than $40 or it weighed less than 1 ounce. Stellar bag.
