WE ARE SAREEN
Sareen was born from a simple frustration: waking up at 3 a.m., too warm, sheets kicked off, cotton pajamas clinging. For women who run hot at night, sleepwear was never designed with them in mind. So we set out to change that. We built our entire brand around one exceptional fabric,
Tencel™ Lyocell, a botanic fiber that wicks moisture faster than cotton and stays naturally cool against the skin. The result: beautifully simple sleepwear that helps you sleep cooler and wake up rested.
Naturally Cooling
Every piece is made from Tencel™ Lyocell
a breathable, moisture-wicking fiber that stays cool to the touch, so you stop overheating at night.
Effortlessly Soft
Silky-smooth and gentle on sensitive skin, Tencel drapes like a second skin. Once you've slept in it, cotton feels like a step backward.
Risk-Free Comfort
Free shipping on every order, dispatch within 1–2 business days, and a 30-day money-back guarantee. If you don't sleep better, send it back.

Made From Tencel™ Lyocell
Each piece embodies our obsession with fabric. Tencel™ Lyocell is derived from eucalyptus wood in a closed-loop process, and it manages moisture significantly better than cotton, keeping you dry and comfortable through the night. It's naturally breathable, gentle on skin, and incredibly soft. One fabric, obsessively chosen, in every single piece we make.
Designed For Real Nights
No stiff, boxy sets. No flimsy synthetics that trap heat. We design in small, considered collections — relaxed cuts, soft piping, colors you'll actually want to be seen in. Sleepwear that does its job so well you forget you're wearing it. Questions? We're real people and we answer fast: support@sareen.com.
