Very very happy with these. Have only used them in winter so far but they seem like they will work really well all year long. Nice quality material as usual. We have loved the Floss design since my daughter was born: from the beanie to the zippy and now the two-piece PJs which are very convenient for nappy changes. I was worried about the sizing (had an older model size 2 of another design which seemed to already fit my 10 months old) compared to the zippy which was very generous in size but the addition of the snap front closure means my daughter will get longer wear out of these (she has a big head). She's in the 97th percentile for her age but she has room to grow in the size 1 and the cuffs on the top and pants mean they still fit well.
