Sleep is the most powerful performance tool you have.
Your bedding should work with your body, not against it.
Our 100% French Flax Linen Fitted Sheet Set is designed for people who treat sleep as a biological advantage.
Soft, naturally breathable, temperature-regulating, linen creates the ideal micro-climate for deeper, more restorative sleep.
Minimal luxury. Maximum recovery.

Linen is the most intelligent natural fiber for sleep. The hollow structure of flax fibers allows air to circulate freely, helping regulate body temperature throughout the night.
This means:
• Cooler sleep in warm environments
• Gentle insulation when temperatures drop
• Less overheating and night sweats
• A dry, breathable sleep surface

Unlike synthetic fabrics or dense cotton, linen works with your body’s thermoregulation, which is a key factor in sleep quality and recovery.
And...
- Exceptionally durable
- Naturally hypoallergenic
- Colouring method that is skin-safe, durable and low-toxicity.
- Oeko-Tex certified
- Sustainably grown with significantly less water than cotton

The fitted Sheet Set includes 3 pieces: 1 fitted sheet and 2 standard pillowcases.
Experience the difference of CASA LINU 100% French Flax Linen.
