In Bali heat, we dress our own kids in double-layer muslin cotton: a romper or playsuit by day, a onesie underneath when it's cooler, and cozy muslin pajamas at night. The open weave lets air move through the fabric, so sweat dries fast and nothing clings. We wash everything often and it only gets softer.
We live in Bali, so heat is just the weather we raise our kids in. Muslin cotton is what we reach for ourselves: it's loose-woven so air gets through, and it gets softer every time it's washed. Everything we make for Epic is what we already put on our own two.
