Soft (after you wash it). Warm.

My friends and I do a good bit of kayak camping. We were going down the Delaware water gap national rec area for 5 nights in September. Late September. Meaning 40 degree nights rather than the mid 50s to low 60s we had been doing. So I needed a new bag. This is the one I chose. Im 6' and 180 lbs. A lot of these usual hiking bags, are narrow, and I feel like im a mummy in them. You cant even roll over usually. I needed more room. Since Im stowing this in a kayak, I was ok with the added gear space. I want comfort. My first impression was. IM SENDING THIS THING BACK. the flannel felt like burlap when I opened it. OMG was I not happy. seriously? But I read some review that said to wash it a bunch. so I threw it in the washer with fabric softener and washed it three times in a row. After that, it was nice and comfortable. And i have sensitive skin, so if its soft to me, then it should be soft to everyone haha. It does take up some space. The bag, a foam mat, and some pillows took up most of the big bag on the front of the yak. But well worth it. stayed more than comfortable , plenty of space and was able to roll over just great.

Excellent value and quality

My family are big campers. I raised my kids as scouts so we use our gear frequently. Our first mummy bags lasted us 10 years or so. They were very well loved. My kids are all pretty much grown so that means we need longer, wider mummy bags that still work for the same temperatures year round. This bag surprised me with how wide it is, and how long. My sons who are both over 6' tall fit with extra length for wiggling feet. I'm also tall, but I'm chunkier than them. I fit a standard mummy bag with only a bit of room to move, but this bag will allow me to roll over comfortably. There's a cell phone pocket to keep track of your important items. The drawstring pulls in fairly tightly so there's little to no cold air getting past that neck ruff. There's a nice cotton flannel lining that with use/washing will soften up beautifully. We'll be very likely to purchase at least 2 more of these bags and hope they will last at least as long as the ones we had previously. This is a fantastic price point for a nice mummy bag. Read more

Great heat, low power consumption

This heated sleeping bag is the bomb. It is warm, efficient, and a great size for just about anyone. It uses only 18 watts on high, so it hardly uses any power at all. One of my favorite purchases. Read more

Very comfortable

Very nice sleeping bag. I’m 5’10”, 225 lbs, and have plenty of room inside. It is soft, comfortable and warm. Washes and dries well, still holding together. Rolls up easily to store in the bag. Read more

Perfect for Big and Tall!

Awesome sleeping bag. Great for cold weather. We camped out in 20° and it kept us toasty. My husband is 6 feet and 275 pounds… he fits in the seat sleeping bag comfortably. Read more

good and bad

So there's good and bad with this after my first night sleeping in it. I sleep in sleeping bags on my bed. My last bag, the flannel got tore up and the filling started spilling out so I needed a new bag. So I bought this one because it's cheap and it has heating elements. Good: - it's warm - it's lightweight - it's relatively cheap - the inside feels durable enough it won't rip like my last bag. Bad: - heating element is NOT rapid, 3 second, instant heat using a 5V2A powerbank. It take about 30 minutes to heat up. - flannel is not really flannel. It seems like it's mixed with polyester, which explains the durability. - zipper is on the wrong side (left side) for me because I exit my bed on the left side of the bed (looking from the foot of the bed). - it's XL but seems like standard size. I'm 5' 11'', 190 lbs. and it's smaller and more cramped compared to my last bag which was an ALPZ Outdoorz -10 degree sleeping bag. I would recommend this for camping, but not everyday sleeping, which is what I am using it for. Read more

It was a lifesaver

I went camping for the first time this weekend during a cold front in Florida and let me tell you this was a life saver. It was warm and comfortable. It was easy to roll back up and it's very lightweight. The lining is flannel so that contributed to the warmth . It had the mummy design so I was able to pull the strings and elastic tighter around so it helped to keep me warm. Read more
