FAQs

What are Sleep Tees made from? 

A breathable bamboo and spandex blend that’s lightweight, soft, and designed to keep you cool.

How does the material feel? 

Light and cool to the touch. It’s soft on your skin and follows your natural silhouette while you sleep. 

How are they different from your Warming Sleep Tees? 

Both styles share the same oversized fit and features (like side pockets), but the fabric is where they differ. Our classic Sleep Tees are made from a lightweight bamboo blend – perfect for hot sleepers, warm climates, or summer nights. 

Warming Sleep Tees use a thicker brushed bamboo that’s soft, cosy, and designed to keep you warmer in cooler temps. Think of it like your summer vs winter Sleep Tee. 

What size are they? 

Sleep Tees are one size fits most. They’re designed to be oversized, generous, and roomy for maximum comfort. For exact measurements, please check the size chart.

How do I wash and care for my Sleep Tee?

To keep it feeling soft, cold machine wash with similar colours and a mild detergent. Avoid bleach or tossing it in the tumble dryer.

    The perfect sleepwear!

    I bought this and the Mang Oodie as I'm a massive ARMY, and I find I get so hot at night when I sleep, so this has been my absolute saviour since I've had it! It's lovely and airy, really roomy and the perfect length and size. I feel so comfortable in this, I'll be getting more sleep tees for the summer!

    Too big for short people

    I find these oodies as one size way to big and heavy for my short frame, I find they tangle around my arms and body when trying to do anything.
