Kids Summer Nightwear & Sleepwear for Warm Weather

Warmer nights can make sleep feel more unsettled, especially if pyjamas feel heavy, clingy or too warm. Natural fibres are often preferred for summer sleep because they feel softer, lighter and less restrictive overnight compared to heavier synthetic materials.

Our kids summer sleepwear is designed to support airflow, moisture control and temperature regulating through the night, helping little ones stay cooler and more comfortable when temperatures rise. Lightweight childrens summer nightwear can also help reduce irritation from sweating and heat rashes, especially for children with sensitive skin or those who naturally run warm.

Kids Cotton Pyjamas & Breathable Bamboo Sleepwear

Our kids cotton pyjamas and breathable bamboo kids sleepwear are crafted from naturally soft fabrics chosen for warm-weather comfort. Each fabric offers something slightly different, so you can choose the feel and fit that suits your child best.

Our ribbed fabric blends bamboo, organic cotton and elastane for a soft, stretchy feel that moves comfortably with wriggly sleepers. Our signature fabric combines organic cotton and bamboo for MORI’s much-loved softness, breathability and everyday comfort. For children up to 8 years, our modal fabric is made from sustainable beechwood tree fibres, creating a silky-soft finish that feels beautifully lightweight against the skin.

These breathable fabrics help with moisture wicking and temperature regulating during warmer nights, making them a thoughtful choice for children who overheat or sweat during sleep.

You can also discover more bedtime favourites through our Sleep Club, where members receive a brand-new pyjama print delivered to their door every month.
