The Calmm Kids Long Sleeve Nightwear Set in Green is a long-sleeve pyjama set for boys and girls aged 5 to 14 years, made from LENZING™ Modal (95%) with 5% Polyurethane. The Modal fabric is considerably softer than standard cotton jersey, breathable despite the long-sleeve cut, and holds its softness and shape after repeated washing — important for a set that will be worn regularly through the week.

Green is a less common choice in children’s nightwear than navy or pink, which makes it a more distinctive option — it works well for children who want something a little different, and it photographs particularly well for Christmas morning and festive content. The long-sleeve design makes it suitable year-round, and the unisex cut means it works across genders without compromise. A matching adult version is available, making it a practical choice for coordinated family nightwear. Also available in Navy and Pink.

Buying Advice:

The long-sleeve cut makes this set comfortable year-round — warm enough for cooler nights without being heavy. LENZING™ Modal is naturally breathable, so it won’t feel clammy in warmer conditions, and the 5% Polyurethane adds gentle stretch for a better fit across different body shapes. The green colourway has a natural, earthy tone that sits well alongside the navy and pink versions if you’re buying for multiple children or siblings. Sizing is relaxed and true to age; size up if your child is tall or between sizes.
