[ I bought this for future, unknown trips. My nephew immediately took it out of the box and got into it. He looked so comfy I decided to try it in my bed and now I just love it and sleep with it. It OPENS on the bottom to stick your feet out. This is why I bought it. I ca n't stand sleeping without sticking my feet out to breathe lol. So, it has n't even made it outdoors yet but the quality and comfort is excellent. I bought it used on the site and it was in excellent condition as described. Has a very nice packing bag as well with straps. This is why outdoor equipment is worth paying a premium; you really get what you pay for and I highly recommend the brand.

[ Great spring and summer bag! Super soft down and silky fabric. I love the zippers to vent, especially when my feet get hot, I can open the bottom and keep warm up top. High quality zippers with extra fill around them to prevent snags and drafts. Love it! Mesh storage bag is a nice addition, but it could be bigger.

[ This is a wonderful sleeping bag to be used during cold temps. Handled single digits well. I used the reactor liner with this bag. I am very impressed with the quality and packability of this version. Would order again!

5 Laura P.
[ I love this sleeping bag. I am a side sleeper who likes their feet out. This bag meets these needs and goes with me everywhere I go. I sleep on my left side, the men's version is the way for me.

Used the bag for a fall hunt in the Brooks Range, Alaska- 150 mile north of the Arctic Circle. It was warm and comfortable. Night time temps were in the low teens to maybe single digits and I was always comfortable, never wanting for more. The arm holes are nice for reading.

5 COLF
[ Used on an overnight in Feb. on Mount Washington, NH. Temp- 10 F, wind 50- 60 mph. Bag kept me warm. Wish I could have used arm holes, but it was too cold! This bag did the job, and ca n't wait to continue to put it through its paces. Got the long to keep my single- lined boots in the bag with me at night. At 5' 9 '', still had plenty of room.

[ I bought this bag for an expedition north of the Arctic Circle, but I have n't left yet. Despite this, I tested the warmth of the bag as well as I could on a- 9F night and was quite comfortable all night. Normally I sleep pretty cold, so I 'm very confident that it will serve my needs in the Northwest Territories next week.

[ I ’ m a 6 ’ 1 ” 195lbs man and wasn ’ t sure if I wanted the regular or long version. I went with the long and boy am I happy with it. I was just doing some winter camping and this bag is kinda like crawling into a hot tub made of down pillows. It ’s great! That night was 5 degrees with solid 15 mph gusts so easily below 0. I was snug as a bug. Quite happy with it! Yea the long size gives me the extra room as I ’ m mostly a side sleeper that likes to pull the extra around my head. I ’ ve tried the regular size and it felt a bit too constricting. 5 star great sleeping bag

[ Outstanding ECW bag that enables great warmth and survivability in extreme cold bivouac and alpine camps. Highly recommended for its cube design, middle zip and pockets to protect, and secure key items that require accessibility from the bag.

WARM! Big, but definitely warm. Love that the zipper is in the center. Also love the pockets inside the sleeping bag.
