There's no single number that fits every home, but most parents in hot, humid places end up keeping the nursery somewhere around 24 to 26°C (mid-70s Fahrenheit), usually with a fan or light air conditioning helping out. Cooler climates often aim for 20 to 22°C, and that range is hard to hit in Bali or Bangkok without heavy AC running all night. A better gauge than the thermostat is your baby's neck or chest: warm and dry is good, damp or hot means too many layers or not enough airflow. Moving air matters as much as the number on the dial.
This is where the fabric does real work. Muslin is cotton woven in an open, loose weave, so the gaps let air move through instead of trapping heat against the skin, and it dries fast after a wash if you're dealing with sweat or spit-up. Epic's pieces use two layers of muslin cotton, pre-washed before they reach you so they arrive soft instead of stiff, sewn with flat seams so nothing digs in, and finished with child-safe dyes and no harsh finishes. The fabric softens more with every wash, and if you notice creases here and there, that's just how loosely woven cotton behaves.
Care follows the same logic in a hot climate. Wash cold on a gentle cycle, then tumble dry low or hang the pieces up, since muslin dries quickly anyway in tropical humidity. Skip fabric softener and high heat, since both work against how muslin is meant to breathe and soften naturally. Sizes run from newborn up to 4 years, and every order ships worldwide with tracked delivery.
