Our ultimate sheets

Our best lyocell sheets, now antimicrobial for their lifetime.

O+L Ionsilk^TM combines our custom-woven Eucalyptus Tencel^TM with industry-leading Polygiene StayFresh^TM Technology.

A more hygienic fabric that lasts longer, feels better, is kinder to the environment and 100% safe for skin.

Silver: An ancient hygiene hack

Silver has been prized for millennia for its magical antimicrobial properties.

Silver ions interrupt bacteria as they’re trying to duplicate. So instead of two bacteria, you get none.

O+L Ionsilk^TM is powered by Polygiene Stay Fresh^TMTechnology.* It’s the same silver technology used in the best outdoor gear and athletic apparel. It’s 100% safe for skin, including the delicate areas around the eyes.

O+L’s Ionsilk^TM is independently lab-tested in the UK for antimicrobial efficacy, reducing bacteria on IonsilkTM fabric by 99.97% after 24 hours.

Its proprietary salt form binds to fabrics durably, like a dye. Meaning the fabric stays fresh and can be washed less throughout its entire lifetime.

*The active ingredient is a biocide = Silver chloride

Designed to make your skin happy

Microbes replicate rapidly on normal bedsheets, contributing to unhappy skin.

The Polygiene StayFresh^TM Technology in O+L Ionsilk^TM stops microbe buildup in its tracks, without disrupting the skin’s natural flora.

O+L’s lyocell is soft, hypoallergenic and Oeko-Tex 100 compliant, meaning no harmful dyes or treatments were used in its manufacture.

The most sustainable bedsheets on the planet

Here’s why we think they are:

Eucalyptus lyocell uses 1/20th the energy and water of cotton to produce. And our Tencel is derived from regenerative forests that have minimal environmental impact.

Polygiene StayFresh^TM Technology allows you to skip a wash (or several) and the sheets will stay fresh. Reducing the impact of detergents, water and reducing energy consumption.

Better sheets start with better textiles

Next-generation luxury demanded rethinking the way we make fabric.

Thread counts are old news, and traditional cotton isn’t optimum for sleep or the planet.

We spent nearly two years rigorously testing, washing, and sleeping in a variety of traditional and cellulosic fabrics in order to make one that was truly special.

PERFECT THREAD DENSITY

Designed for softness, breathability and comfort.

Comparable in feel to 1000 thread count Egyptian cotton, O+L’s eucalyptus fabric is a 300 thread count, meaning it’s cooler and breathes better than the best cotton.

We weave it in a sateen weave, but with lyocell, this is creates fabric that has sheen but remains crisp to the touch.

THE MOST ADVANCED LYOCELL FIBERS

Long-staple Tencel^TM lyocell fibres are more expensive, but there’s good reason to pay more.

The lyocell we use in Owl + Lark sheets is a specially formulated so it does not easily pill and has much greater durability than normal lyocell.

Not only that, the fabric gets softer with each wash.

A FITTED SHEET THAT FITS

1. At 40cm deep, enough for an O+L Mattress, or any other mattress and a topper and mattress protector.

2. Thick non-slip elastic all the way around.

3. Deliberately tightly fit for that crisp feeling when you get into bed.
