- EQEvelyn Q.Verified BuyerRated 4 out of 5 stars3 months agoNice looking set but shirt could be a bit longer cut
This set is a one-step outfit. If 3Y shirt was 1 inch longer it would be perfect. Will size up.

Behind the brand
As parents, we couldn’t find kids’ clothing built to the same standard as our own premium activewear. So we built it.
AdventureKnit™ performance fabric. Thoughtful construction. Built to move, hold its shape, and be passed down.
Easy to put on. Fun to wear. Finally in their size.
