Question: What is the fill?  Is it down or hollowfill?
Document: I was suspicious of the claim that a $55 polyester fill sleeping bag was good to -10, so I tried this one on the deck last night in 14 degree weather.It's a good thing I did. I was back indoors shortly after midnight.The black bag alone was not warm enough - the top doesn't close tightly so cold air rushed in.
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 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.
We bought and had shipped three for less than the price of one from a big box sports store.
Warm!
WOW!!!!!!! I was expecting a used, smelly 2nd hand sleeping bag but this arrived BRAND NEW and has never been issued, which I confirmed just by getting into it. Absolutely what you want when out enjoying the trails in cold(er) weather. I wanted one for emergencies and now that I received this and tried it, I'm ordering  one for each car.Great company!!! Delivered within days. I seriously couldn't be happier!! !
Very well made, durable sleeping bag. Also, extremely warm, this is very much a winter bag so expect to sweat if you use it in the warmer months.
This seller also put two nice New Years calendars in the box with the sleeping bag.
