Marmot Helium
By Steve_P
Ranked #193 - 25 to 5 Degree Down Bags
September 15, 2009
I've had this bag for about a year. I consider myself an average sleeper for warmth and would rate it comfy at ~25F with long underwear.
Positives: light weight for the warmth- the long weighs 2lb 4oz in a 1 oz silnylon sack. Great construction like all marmot gear.
Negatives: no draft collar. IMO this is a bad omission as this one ounce addition can easily add 10F of warmth; I can feel the heat escaping across my upper chest. The cut is too big, esp from the waist up. You could fit a 300 pounder in this thing and I don't see too many 300 pounders backpacking :)
Summary: make the cut a bit smaller and add a draft collar; it would be both lighter and warmer and fit 99.9%

I use a womens model helium for this reason. I'm 6'2 210lbs and a womens regular fits me fine.

I'm 177cm 75kg and to me it feels quite spacious in the torso area which is great if you dont like being constricted or if you need to add extra layers.

Some hikers are tall and long-limbed. There are few bags that fit us and so many that are narrow and encroaching. Don't change the bag.
