Sleep cooler.
Finally.

Our Copper flat sheet is woven from breathable copper-infused bamboo viscose, so it moves heat and humidity away from your skin as you sleep instead of trapping it the way cotton can. It sleeps cooler than cotton — made for the body that runs hot.

Yes — this is a single flat sheet, sold à la carte in your exact size. No fitted sheet or pillowcases are included. It's the top layer on its own: perfect for replacing a flat sheet that wore out before the rest of your set, or for buying just the piece you actually need.

Our flat sheet is generously cut for full coverage and an easy tuck-in across every standard size. Just match your mattress size — check the size guide for exact dimensions before you order.

Sleep on it for 30 nights. If it's not your favorite sheet, send it back for a full refund — returns are free, with no restocking fee. The whole point of the 30-night sleep trial is to let you decide in your own bed, not in a store.

Shipping is free on all U.S. orders (continental US). Orders to Alaska, Hawaii, and international destinations are calculated at checkout. Most orders ship within about one business day, with 3 to 5 days in transit after that.

Yes. The copper-infused bamboo viscose is naturally hypoallergenic and gentle against sensitive skin, and the copper is woven directly into the fabric rather than applied as a surface chemical coating.

Care is simple: machine wash cold on a gentle cycle, tumble dry low or hang to dry, and skip bleach, fabric softener, and ironing. It's backed by a 1-year warranty that covers manufacturing defects — including pilling under normal care — with a replacement.

Bamboo is a naturally absorbent fiber — part of what makes it feel cool and breathe so well — so it can pick up face and body oils, lotions, and hair and skincare products more readily than a synthetic blend. Those oils can soak in and leave a dark, splotchy mark, usually around the pillow. It's how the fiber behaves, not a defect.

A couple of things keep it from happening: wash before the first use, and head to bed with clean, dry skin and hair so lotions and oils have time to absorb. One thing to watch — benzoyl peroxide in acne products can bleach color out of sheets and pillowcases (any brand, any colored bedding), so let it dry fully before bed or use a dedicated white pillowcase.

If a stain does happen, treat it fresh: blot, rinse with cold water, work in a little grease-cutting dish soap or an enzyme-free remover, and air-dry — never tumble-dry until the mark is fully gone, since heat sets it.
