My Favorite piece of backpacking gear!

I am 6’3” about 350lbs. I have used this set up in both the Catskills and the Adirondack Mountains. I have slept like a rock every time i brought this. I used a sleeping bag liner when temperatures dipped to 28 degrees in march and I completely unzipped this into a blanket when the nighttime lows were 70 degrees this past June. I will never sleep on a pad without this sleeping bag because the bottom portion acts as a bed sheet which is awesome! And the hood stops my camp pillows from sliding all over the place. I sleep almost as good in the back country as i do at home thanks to ATEPA!!! I highly recommend this product!!!

Warm and thick like a blanket

The sleeping bag is maneuverable by ways of the zipper position which can go from mummy bag, to full blown blanket for 3 people. It's fairly long and once you get in gets warm to hot fast depending on the temperature outside. I haven't had the need to zip up fully around 40�� temps cause I'll start to sweat in it. The bag is lightweight but super bulky. You can backpack in it but preferably camping trips would be easier to manage.

Good sleeping bag, nice and warm

I read through some of the other reviews, and I don't know if they got bad bags because I didn't have any issues with this bag. I am a tall guy at 6' 4", and 245 lbs, so not small by any means, and this sleeping bag fit me perfectly. It didn't feel like it didn't have enough down in it, and it got down to like 50 or so degrees at night when I have used it, and I actually opened up my feet at first to air it out and get a little cooler, then as the night cooled off, I zipped it back up and was plenty warm all night.If you were using this on the extreme ends of the sleeping bag at like 20 to 30 degrees, then I'm sure it would be colder, but this is made to be more lightweight and less for really cold areas. I really don't see any issues with this sleeping bag, and would definitely recommend it.
