Question: I've seen a few reviews that say this is a 'mummy' style bag but the pictures show a traditional rectangular style bag. Which is it: mummy or regular?
Document: It easily rolls up for storage in its accompanying compression stuff sack (see below for more info).As a recent reviewer had noted, the photos of the sleeping bag are a bit misleading. The product photos showed a traditional "rectangle" bag, when in fact, I received a "mummy" style bag as the earlier reviewer also had. No problem... cuts down on overall pack size, and is a bit lighter in weight. Length-wise, it was more than adequate for me as I am only about 5'8" tall.
I bought this for a 3 day scout outing for 40deg nights.It does pack down into a nice small cube, tho the compression sack is a little non standard...it did fit IN my pack.Im a little confused by the ratings...I was shivering in clothes on a 42degree night.In addition; the image shows a rectangular bag and I received a mummy style...as a 6' 230lb adult...it was too small.Probably great for smaller frames in greater than 50deg weather.Personally im returning it but it can work in the right situation for the right person.
- 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.
I like the roomy leg compartment of this bag compared to a mummy style bag. My son really likes how the bag is rounded at the top and extends beyond your head for added comfort (you can also secure this area around your head for added warmth, similar to a hood on a jacket). I have camped comfortably in evening temperatures in the upper thirtys with the addition of a thermarest base camp pad under this bag. I also like the asthetics of the colors and design. As I mentioned, we have two of these and one came as left hand zip and the other as right hand zip so it must be random.
This is a fantastic bag. I used it in Africa, from mild to fairly cold temps, rain too. Very comfortable and easy to re-pack. It's small and light, great for traveling. The bag was plenty long and had room to spare in the head area -  I'm 5'5&#34;. I also used a mummy liner and that made for a great nights' sleep.
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.
The first time I tried this the temperature dropped into the 60s. I froze, and adding extra clothing layers didn't help. I ended up calling it quits and heading back home. Sadly I tried it months after I bought it, and now have missed the return window. This would probably work great to sleep in on a cool Summer's night - but why would I want a mummy bag on a Summer's night?
Everything that the package says its true about ultralight, small, straps, etc. It is not a winter sleeping bag for sure. It got down I guess 40 degrees or lower (to be honest I never check) but colder than the city for sure and I was cold the entire night. I only had one layer of jeans and I blame that for it. My upper body was fully warm do to layers that I had. Next time I will put on extra pants....I had a feeling I won't like mummy sleeping bags and I was right... not much room inside to move, but the advantages is the weight!!!
Seriously...again, if you're the type that tends to sleep on your sides, then consider a bag with a bit wider dimensions. It'll save you a lot of discomfort later when on the trails / out camping.Temperature Range: As for the bag's listed temperature rating... I'd honestly have to say that it's about 10 degrees out of range in terms of warmth. You could use it comfortably in 50  degrees, but anything lower and I would suggest a fleece liner for added warmth as this is really just a 3-season sleeping bag not meant for Winter / arctic conditions anyway.
I haven't seen this mentioned:the zipper is 2 part.there is a zipper for the sideand a zipper for the bottom of the bag - it does not go around the corner.good? i guess you can vent your feetbad? the corner will never really be air tight down at the feet - there is a gap.fear:  just trying it out - i fear the zippers will unzip with normal use at the corner. they don't really lock. I guess you could velcro loop or zip tie them.Also -  just trying it out - i had a terrible time keeping the bag fabric out of the zipper.
Answer: yes
