Way too cold

I tried to use this bag for a year or so and ended up returning it.

Even camping in the coastal redwoods in late summer, with nights in the mid 50s, I was freezing wearing every piece of clothing I had, plus my girlfriend's clothes, plus my lower torso inside my backpack. And that's with a Big Agnes insulated 2.5" thick air mattress.

The EN comfort rating of 50F makes way more sense than the original claimed 40F rating.

Love it

I ordered five warm weather bags from Backcountry. I found this bag to be the best value and sent the rest back. the foot box is the largest and the zipper slides the best. the bag seemed to have the most room for wider shoulders and rounder mid-section like mine. If you are really skinny than try it but others might provide a tighter fit. Weight is incredibly nothing. One can compress the stuff sack by roughly 20% if needed.

Other bags ordered but sent back:
• Western Mountaineering Highlite 35 degrees down
• Marmot Plasma 40 degrees down
• Marmot Atom 40 degrees down
• Super Spiral Hugger #5 40 degree

Fire Breathing Dragon of Awesomeness!!!!

Just returned from a three day loop in CO with this red devil of warmth. The first morning after camping at 11k feet I woke shockingly to find frozen water. At least an inch thick of solid ice at the top of my cooking pan! I slept like a baby the entire night using my Arete as an open quilt. Granted I was wearing a light down jacket, and medium socks. Everyone else in the group froze that night using significantly warmer bags (30 & 25). You can't go wrong with this bag, especially weighing in at under 2 lbs, are you kidding ME!!

Excellent lightweight summer bag!

I used this bag for the first time on Memorial Day weekend on a remote Maine lake inside a Marmot Limelight 2 tent with an insulated Big Agnes sleeping pad. I was toasty warm with just underwear and had to keep the bag open near the shoulders until the early morning hours when the temps dropped into the 40's with a stiff breeze and drizzle. The bag really compresses well and lofts nicely once out of the stuff sack. I'm very satisfied with the warmth, compressibility, and weight. This is a great summer bag and I'm very happy with the quality and workmanship. This is my first down bag and I'll never go bag to a synthetic. I would recommend this bag to anyone looking for a warm and light summer bag. I'm really glad that I purchased a Marmot bag. Excellent summer bag!

Hey guys,

What's the size of the bag after its been thrown in it's stuff sack?

Stuff sack that is included is 6x12". Several other owners have posted reviews that you can compress it a little more with a compression stuff sack.

How does this compare to the Atom ? Is the weight/fill the only difference... Which is better?

Best Answer Responded on

Good Questions. You are correct, the main difference is the Atom is using a higher fill power (850 vs 800) making it slightly lighter and a bit more durable. With these warmer weather bags there is less of an difference in weights between 800 and 850 since they use less fill. Overall, they are both great bags and it's hard to go wrong with either one.

Responded on

Actually the Arete is a little more durable. The shell material marmot uses on the atom, hydrogen, helium, lithium is ultra light and a little less durable and down proof than that on the Arete,arrayo, pinnacle,col, and cwm.

perfect summer sleeper

With 800 fill goose down, this seems to be the perfect summer bag. I also ordered the Sea to Summit EVent compression Dry sack (small) and it fits perfectly. It compresses to approximately the size of a Nalgene bottle (slightly larger diameter). I am now able to stuff this bag and a full size thermarest mat in the sleeping bag compartment of my Deuter Aircontact 65+10 backpack. This bag doesn't dissapoint!

Responded on

Hi Chuck - did you use the 10 liter EVent compression sack or the 6 liter? Thanks!

Responded on

10 liter. I think the 6L is the XS. No way it will fit. The 10L is the perfect fit for this bag.

Does this bag have loops on the outside to strap to a sleeping pad?

Super summer sleeping bag

This is currently my favorite summer sleeping bag on the market right now. I like the way Marmot cuts their bags (wider in the shoulders than Mountain Hardwear), the way the hood fits, and the roomy footbox. The bag itself is super light with 800+ fill down and compresses quite well (an puffs back up quite nice). The only thing you need is a waterproof stuff sack!

how small dose this bag pack? and would you recomend for lightweght backpacking

Responded on

The stuff sack size is 6" x 12" but will pack smaller in a compression stuff sack. This is a good 40 degree lightweight sleeping bag.

Responded on

This is the perfect UL warm climate bag. Packs down to ~ 4 X 8. I used this on a fast pack across the Big Island of Hawai'i in temps from 30 to 50 degrees.

Teeny and warmer than advertised

I am a really cold sleeper, I got this for sultry summer nights only. I always seem to underestimate desert nighttime temperature drops and I've actually used it down to about 25 degrees (which was pretty uncomfortable). But I was fine in the 30-40 degree range. The best part is its negligible weight and amazing packability.

does this bag have a zip along the foot...

does this bag have a zip along the foot of the bag for warmer weather? I am a warm sleeper and need the option of this, but want a bag that is still going to be warm enough with everything zipped up in slightly cooler weather....If not - is there another bag that offers this?thanks,Dave

Best Answer Responded on

it has a double zipper on the side that you can vent near your foot but it does not have a dedicated zipper for the footbox itself
