I'm a big fan of our single Blueberry Cover that I got from a seconds sale. It is a mini coverall and has 3 settings for rise and inner leg gussets. It's easy to get a good fit with and the Velcro is stronger than our Thirsties covers. I like that the cover is all one color instead of having white trimming. It's less distracting if it shows out from under an outfit.
Update - 5 months: We needed some bigger covers and I have liked out blueberry the best, so we have 2 more of those now.
