If you sleep hot, this linen flat sheet oat is made for you — 100% stone-washed French linen in a soft oat neutral that calms your bed. The hollow flax fibres pull heat and moisture away from your skin and breathe far better than cotton, so you stay dry and cool instead of kicking the covers off at 2 a.m.

Stone-washing gives it a lived-in, relaxed softness from the very first night, and unlike cotton it only gets softer and more characterful with every wash — naturally temperature-regulating in summer and winter alike.

Care

Overview

Flax is 100% stone-washed French linen in a soft oat neutral, made for hot sleepers. The hollow fibres of linen draw heat and moisture away from the skin and breathe much better than cotton, so you stay dry and cool and are not kicking the covers off at 2am.

Stone-washing gives it a relaxed, lived-in softness from the first night, and where cotton wears, linen gets softer with each wash. It regulates temperature naturally in summer and winter.

Care

Machine wash at 30°C on a gentle cycle. Tumble dry low or dry on the line. No bleach and no softener. Iron on medium if you want to; we never do.

Materials

100% French flax linen, approx. 170 GSM, pre-washed with a stone-washed finish, colour dyed before weaving.

For people who sleep hot

Linen carries heat away from your body through the night, so you stay dry, cool and asleep, even in midsummer.

A texture you can feel

The relaxed, stone-washed rumple is not styling. It is how the sheet arrives, soft and ready to use.

No more 3am sweats

I run hot every night and used to wake up damp. This sheet breathes so well I sleep straight through now. The oat colour is even prettier in person.

Finally, real linen

You feel the quality the second you unfold it — weighty, textured, cool to the touch. Keeps me dry and comfortable all night.

Softer every week

Crisp at first, buttery after three washes. Cool all night even in a heatwave — I'm replacing all our cotton with these.

Frequently asked questions

Why does linen suit hot sleepers?
Flax fibres are hollow by nature, so they draw heat and moisture away from the skin and do not hold it as cotton does.
Is it scratchy?
No. Stone-washing breaks in the fibres before the sheet reaches you, so it arrives soft and gets softer with each wash.
How can I select a size?
Choose a flat sheet about 40–60 cm wider than your mattress, so there is enough to tuck in. Nine sizes cover beds from single to super-king.
How is it washed?
Machine wash at 30°C on a gentle cycle, then tumble dry low or dry on the line. No bleach or fabric softener is needed with linen.
Does the colour fade?
The yarn is dyed before it is woven, so over the years the colour softens and does not wash out.
Is it a fitted sheet or a flat sheet?
It is a flat sheet (1 piece). Use it as a top sheet, or alone as a light layer in summer.
