Marmot Helium Sleeping Bag: 15 Degree Down - Women's - 2008 BCS

One trick I've learned is to turn the bag inside-out before stuffing it in. The outer shell of the bag is treated with DWR for wind and water resistance, so it's harder for air trapped inside the bag to escape. When you flip it inside-out, it's easier for excess air to escape through the inner layer of the sleeping bag. Hope this is helpful!

I agree with you about the XS size. Western Mountaineering does the same thing. I suggest using a S size compression stuff sack. You will then be able to control how much you want to compress your 850 fill sleeping bag. I feel the less compression on the higher loft down the better the bag will work. In fact I stuff mine in my day pack along with a few other down items which all fit neatly in the bottom compartment of my pack. Just a thought.

Unzip it part way and start by stuffing the bottom of the bag in first. Just keep packin' and stuff the hood last. If you stuff the hood first it traps air in there and makes it a little more difficult. Hope that helps.

Sure, these will fit you best. Good way to go! Plus these do really have extra down fill through the footbox, as compared to the men's version- warm feet is NEVER a bad thing :)

I dont understand the previous answer, but have the same question, is the women's regular bag adaquate for someone who is 5'7?

I agree with Mike entirely. The regular Helium (item# MAR 1119) will not only come in a length that fits your height, it's going to be more spacious in the circumference measurements at 64/60/42 compared to this one at 58/58/38, and it weighs only an additional 2oz. A regular size in that model will fit a person up to 6 feet tall, and it costs the same.
