Moon and Back by Hanna Andersson Organic Cotton Leggings vs Simple Joys by Carter's Baby Girls' 4-Pack of Pants

At the same price point, Carter's gives you one extra pair per pack. That's not a rounding error — with toddlers, an extra pair is the difference between making it to laundry day and doing an emergency wash at 10pm. For parents cycling through leggings daily, Carter's 4-pack is the more practical buy.

Carter's uses soft cotton, but it's conventional — grown and processed with pesticides and finished with chemical treatments that stay in the fabric. Moon and Back's GOTS certification means the cotton is organic from field to finished product. For babies with sensitive skin or parents who are deliberate about what touches their kid's body for 12 hours a day, that certification is worth the one fewer pair.

Both products use cotton-dominant construction without meaningful spandex content, so neither moves like an athletic legging. Moon and Back's organic cotton is actually slightly stiffer than conventional cotton, which can be noticeable on active toddlers. Carter's has the edge here simply because its conventional cotton is softer out of the wash — and its sizing is battle-tested across millions of kids.

Organic cotton is more prone to shrinkage than conventional cotton if you're throwing everything in a hot wash and high-heat dry — which is exactly what parents of toddlers do. Carter's conventional cotton is more forgiving in the laundry. If you're not reading care labels (and most parents aren't), Carter's will hold its size and shape longer in real-world conditions.
