Mix and match our TOG-rated Layers, designed to be worn as a pyjama underneath any of our swaddles or pouches for sleep, or on their own as daywear. Layers are the sleep essential designed to be worn under your baby's swaddle or sleeping bag, as part of our TOG-rated What to Wear sleep system. Made from a deliciously soft, stretchy organic jersey cotton, Layers can be worn as either the base layer (closest layer to baby's skin), a mid layer with a singlet or bodysuit underneath, or as daywear too! An extra-thick TOG-rated Layer for wearing under your swaddle or pouch, in room temperatures down to 12°C.
