Question: what are the snaps on either side of the zipper for?
Document: It is very very warm and my fav part is the zipper super thick and durable and doesn't snag as often as other sleeping bags. Plus the price I mean come on rei comparable bag would coast you 200 dollars. The differance is it is a little heavy 4lbs compared to rei bags that are 2lb
The bag looks to be made to handle the abuse of combat, and it very well designed for outdoor adventure abuse. I plan on using this in conjunction with the military gore-tex bivy sack and green patrol bag. I like the fact that all the bags have interconnecting snaps to hold them all in place.
$9. I needn't say more but amazon is forcing me to even tho I'm doing them a favor by reviewing. Anyway... Mine came very clean. I found no rips or tears or repairs. The zipper is solid and shows the only real sign of wear. I love this bag. I paid $18 with 9 of it going to the seller. So even if it was $20 I'd be a very very &#34;Happy Camper&#34;.
We bought three of these bags hoping they would be of better quality than the sports retailers bags. Holy moly!! They are definately military rated bags! Very durable material, and an awesome zipper that won't snag!. They fit my wife and son extremely well, but is just a bit short to be used as an extreme weather mummy bag for my 6'4&#34; frame. Will still work wonderfully in normal weather where my head doesnt have to be inside bag.
I was in the Army for over 23 years so I know what these type of sleeping bags look like and go through. When mine arrived it was sealed in a vacuum bag, it was clean and did smell like old Army gear! In short it was in much better shape than many that I was issued from CFI (Central Issue Facility) while I was active duty. All the zippers & snaps are present and serviceable & I haven't found any rips or tears.
very warm great price  to short for me,so girl uses il now  I bought the longer bag for myself  thanx  not for people over 5feet tall
the sleeping i got was like new,I don't think it was ever used,no rips or even a hint of smell of being used.nice and warm too.
sleeping bag was in perfect condition considering it was new I expected I would have to patch a few holes and wash but was clean and it awesome condition when received very happy would order from this seller again without hesitation.
We bought and had shipped three for less than the price of one from a big box sports store.
Warm!
