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.

    BT21 & the Oodie = Perfect Combination!

    Purchasing the BT21 Group Oodie Sleep Tee has been one of the best decisions I've ever made. Insanely soft material that feels smoother than silk on the skin. The quality is top notch, the design is printed clearly and good saturation. Colours are vibrant and the fit is so comfortable. It's oversized but not cumbersome at all. Let's talk about the stretch...what a generous fit and give to the fabric.

    I have already washed my BT21 Group sleep tee and it has held up brilliantly. I ran it through a warm/cool cycle and I chose to run it through the dryer as well. I realize I was going against recommended care instructions to lay flat to dry/air dry but I was willing to accept the consequences of putting it in the dryer.

    Funny thing is there was no significant shrinkage like I was fully expecting it to. Full disclosure, there was some shrinkage both in length and width but not significant enough to say it ruined the sizing/fit. Also, the fabric was still soft enough for my liking with no major change in texture/feel. Again, based on my personal preference/opinion.

    For those who are very particular about keeping the "new" feeling and sizing for long as possible, it's best to follow the official care instructions but I don't have the patience or time to air dry so I chose to tumble dry with great results. Win-win all around for me!

    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.
