I ordered these, not thinking too much about them, so it was a very pleasant surprise when I got them, used them, and realized they are the PERFECT onesie.  They are super soft cotton, not too thin and not too thick.  Instead of a collar side snaps or snaps down the back, these have the criss-cross design on each shoulder which is designed perfectly to provide the extra room when pulling on/off and they don't result in a too wide and awkward-shaped neck opening, which I have found to be the case for some with the same design.  And the best thing of all that I love, love, love is the additional row of snaps so that the onesie can be used over a much longer period of time. To me that alone justifies buying these, but the fact that they are also made well and are super soft... yep, I'm sold!
