Question: Can two of these bags be zipped together to form a larger bag?  (I'm aware it means a bit of pillow fluff in someone else's face if it can be.)
Document: Width-wise, it leaves a bit to be desired. If you're the type to sleep flat on your back facing upwards all night, no problem. But if you're like me and shift to sleep on your sides (fetal position) throughout the night, then this bag may not be for you. I'm not a big guy by any means...pretty average build, if anything. Sleeping on my side was just way too tight as the bag was not wide enough for such a position. At times I was afraid that I might overstretch the bag and break the zipper's bond.
I read reviews often but rarely contribute unless I either really like or dislike a product. I'm a big fan of this bag. I'm 6' 190lbs and the fit is great. I tend to alternate sleeping on my back and side and find it easy to rotate in the bag. I appreciate the bags compact &#34;packed&#34; size that easily fits into the sleeping bag compartment at the bottom of my North Face Badlands 60 pack. My &#34;Scout&#34; aged son has the same bag and it fits easily into the sleeping bag compartment of his Teton Sport Explorer 4000 pack.
- little drops of water on it here 'n there), but no more than that.... meaning, it's not going to be waterproof.The zipper seems ok, as long as you use proper care when zipping and unzipping your bag, being cautious not to snag the fabric. There are two seperate sets of zipper points....one that runs the full side length of the bag, and another that runs along the bottom. It is not one continuous zipper line that traditional rectangle-style bags tend to use.It's fairly light in weight at around 3 pounds at most, just right for lightweight backpacking use.
Bag is good, got down to about 40 degrees last I used it and kept me warm. I'm 6'2 and its long enough. Zippers are good and it is light. The bad was the sack it came with. Strap broke on two sides first pull to sinch it down. Not a big deal as I had other sacks.
Very good product on heat preservation. I have only been using the sleep bag in the cold dorm room so far; but it keeps me warm throughout the night. Excited to use it outdoor soon! It would be a even better product if it is a bit more elastic, since I'm a &#34;fetal-position&#34; sleeper.
We bought 2 of these bags for our 3 day hike in early August in Northern NH. I'm 5'8&#34; and my husband is 6'3&#34;. Bags are long and roomy enough to provide a very nice sleeping. There was no problem whatsoever in the tent - nights were warm enough - about 52 - 64F and bag allowed enough warmth and an option to easily open up to cool down. First night was rainy and we had to keep tent all close against that rain. Tent's inside got a little of accumulation and bags were slightly dump.
Pros- Compresses nicely- the compression bag actually seems a little large!Good length- slightly longer than my camp matress, which is perfect  because it allows my feet to hang off the edge : ) (I'm 5'9&#34;)Cozy- for the weather I've been in which was 50- 60 degrees.Love the cutout area for my pillow- it even has a drawstring it I want it snug around my head.Cons- It's made by a Japanese company so it opens to the leftdescription discrepancy-I would not think this suitable alone for 30 degree weather!
I used this for 3 months of traveling in coldish weather. Realistically, it's probably comfortable for outside temperatures anywhere between 45-70F. It's very durable. The one thing I wish is that it was a bit bigger- I'm 5'5&#34; but I like to stretch out when I sleep, and you can't really do that with this.
This Sleeping bag I have been using for quite some time now. Zipper still works (I abuse my sleeping bags). It is light to carry and keeps you warm to about 40....
This makes rolling up the bag a PITA. You have to keep constant pressure while trying to put the sleeping bag back into the compression bag.3. The shell is slick. Just wanted to say that again.Should you get this? yes. I got two. One for me and one for my son for a BSA hiking trip. It worked nicely. My main problem was waiting for the night to get cool enough for me to get inside it.
