This is an ErgoPouch Cocoon Swaddle. The size is newborn to 3 months. I purchased it in July, but I didn't check properly and bought the all-season version. It was too hot to use, so I bought a summer version and am now selling this one. It's new and unused, and I haven't washed it, but it has been opened once, so please understand that it is not in the same condition as in a store. Returns and refunds are not accepted.
