Cooler by Nature

Micro-gap bamboo fibres wick moisture 3.5× faster than cotton, helping hot sleepers stay cool through menopause nights.

The Cooling Science

Sleep Is Chemistry,
Not Just Comfort

Heat naturally escapes through bamboo's micro-gap fibre structure instead of becoming trapped beneath your bedding.

  • Releases trapped body heat naturally
  • Wicks moisture before it builds up
  • Keeps airflow moving through the fabric all night

Effortless upkeep

How to care for your bamboo sheet

Three simple steps.

How to care for your bamboo sheet
01

Machine wash cold

Gentle cycle, cold water, mild detergent. Skip bleach and fabric softener to protect the fibre.

02

Tumble dry low or air dry

Dry on low heat or line dry. Remove promptly to keep that signature smooth, wrinkle-free drape.

03

Store cool & dry

Keep spare sets in a cool, dry place away from direct sun to preserve colour and softness.

The perfect cool top layer

I sleep with just a flat sheet most of the year and this one is a revelation — cool, weightless and silky. I stopped waking up hot within the first week.

Cool and wrinkle-free

Runs cool all night and comes out of the dryer basically smooth. The elastic is strong without being a wrestling match to put on. Exactly what I wanted.

Feather-light and soft

So lightweight it almost floats. Docked half a star only because I wanted a deeper Sage, but the softness and drape are genuinely luxurious.

Softer every single wash

It started silky and somehow keeps improving. No pilling, dries fast, and barely wrinkles. Easiest premium sheet I have ever owned.

Breathes like nothing else

Cotton sheets always felt clammy by morning. This bamboo one actually lets air move — I run hot and finally stay dry all night. Layers beautifully under the duvet too.

Lovely, order generous

Cooling and softness are excellent. A star off because the drop was a little short on my deep mattress — size up if yours is tall.

Hotel-quality layering

Tucked under our duvet it makes the whole bed feel like a five-star suite. Cool against the skin and the finish looks far more expensive than it was.

Effortless to care for

Wash cold, tumble low, back on the bed looking crisp. No ironing needed. I bought a second in a different colour immediately.

Good to know

Questions, answered

Will these actually keep me cooler?

Yes. Bamboo lyocell moves heat and moisture away from your skin rather than trapping it, so the surface stays cool to the touch and dries faster through the night — most hot sleepers feel the difference on the first night.

How is bamboo different from cotton or "cooling" polyester?

Cotton absorbs moisture and holds it against you; polyester feels cool at first but doesn't breathe, so heat builds up. Bamboo lyocell is naturally breathable and wicking, and — unlike synthetics — it gets softer with every wash.

How do I wash them?

Machine wash cold on a gentle cycle and tumble dry low. Skip bleach and fabric softener — the bamboo fibre stays soft on its own, and softeners can coat it and reduce breathability.

Are they safe for sensitive skin?

Absolutely. They're OEKO-TEX® Standard 100 certified — tested free of harmful substances — and naturally hypoallergenic and antibacterial, which makes them gentle on skin and kinder to breakout-prone complexions.

What if they're not for me?

Sleep on them for 30 nights. If you're not cooler and more comfortable, return them free for a full refund — even if they've been washed. Every set is also backed by our lifetime craftsmanship guarantee.
