Rated 2 out of 5Â by Verified Reviewer Very thin
We purchased our first muslin Aden + Anais sleep sack from a local baby store and loved it. When our son outgrew it, we tried to order the same thing in a larger size from Kohl's. This one is very, very thin -- you can see right through it -- and won't keep your child warm at night. I have to imagine it's just for the hot summer months. I've purchased muslin sleep sacks in this brand before and they are thick and quilt up after a few washes -- very nice for chillier weather. If thin is what you want -- to keep your child from climbing out of the crib or something -- then this will be fine, but I can't imagine it adds any warmth at all.
