Great product for nestling your packer. I'm usually a M/L, but the waistband was a little tight. It's still wearable though, and if used for pack-and-play you would want it to be a bit tight. It will likely only fit the packer that it was made to pair with as the harness hole is fairly small. I do think the hole is primarily for gender euphoria reasons and less for pack-and-play because of the size and texture of the packer.
