This is basically a fleece blanket with a zipper. I bought 4 of these and had them monogrammed with the grand kids names and they love them. The personalization really makes them feel special. When all are here together, they sleep in the same room on air mattresses and we call it the bunkhouse, They're easy to launder, store, and warm enough for inside use.
It was my husband's idea to get these. We had slept in our new beach condo's king-size bed and struggled with sharing the covers all night...and couldn't stay warm. He thought these would keep us comfy/cozy and then we could just wash the bags, (rather than transporting the king-size bedding back-and-forth to launder).
It worked like a charm! We purchased 2 twin-sized bags. They are very warm, comfy, and easy to transport/wash. Just the right size (room to move, but cozy). We kept them between the bed sheets during our stay. Nice to nap in, too.
We got one in another color for guests. Our first guest got so excited! She's getting one for her granddaughter, and some for travelling. She always carries her own pillow, and I'm sure having her own portable "blanket-bed" appealed to her, too.
I love this! Washed and dried great, and just the weight I needed for spring. I used a regular sleeping bag under it for padding, and it was fine, but I wouldn't recommend using it without something under it to pad the ground/floor/whatever. It's soft and cuddly, yet not heavy enough to make you too warm while sleeping.
