Plush 3 layers, 20″ wide by 24″ long, this snuggle sack is soft and cozy. A layer of snuggle flannel, and then quilt batting in the middle and a layer of fleece. I use a premium, non-allergenic quilt batting that is 4 ounces per linear yard, bonded to resist tearing, shred less and will not come through the fabric like most batting. It is sewn into all the seams; the two sides, bottom and around the top. This keeps it from shifting when washed. You can see the thickness and quality of this bag in the pictures of above. It is folded halfway down so it is easy for you to see the color of both sides. It is reversible and the length can be adjusted, just turn it down as far as you like.
