These cotton sleep-and-play zip-ups by Gerber are terrific. They are nice and light for spring/summer weather and do not shrink much at all after washing. The patterns and colors are very nice, and what is more, they zip up. Typically, footed pajamas come with snaps, which can be a giant pain in the neck if and when baby is being fussy during a diaper change etc.
For the price, you can't find a better deal. In fact, I own multiple sets of this 3-pack in various sizes. Gerber can always be counted upon to deliver quality at a fair price.
