Buying guide
For hot climates, double-layer muslin cotton is the strongest choice because its open, loose weave lets air move through the fabric, keeps it lightweight against the skin, and dries quickly after a wash. Bamboo fabric feels soft too, but muslin's quick-drying, breathable weave makes it the easier fabric for daily heat.

We're Vanessa and Bob, and we design our kids' clothes in Bali, where hot and humid is just the weather. Parents ask us all the time: does muslin, bamboo, or plain cotton keep a baby cooler? The honest answer is that the weave matters more than the fiber, since a loose, open weave breathes far better than a tight one, no matter which fabric it started as.
A one-piece for warm days, the loose muslin weave keeps air moving over arms and legs while flat seams stay comfortable against warm skin.
Simple and quick to change, the double-layer muslin keeps it light for everyday wear, and it gets softer every time you wash it.
Loose enough for a toddler on the move, the open weave lets heat escape while they run around in the sun.
Two pieces you can mix, both in the same breathable muslin, so you can dress for a hot day without extra layers.
Yes. Its open, loose weave lets air move through the fabric, so it stays cooler against the skin than a tightly woven cotton.
Wash cold on a gentle cycle, then tumble dry low or hang to dry. Skip fabric softener and high heat, and expect some creasing, that's normal for this weave.
