Not just soft.
Cooling soft.
Three reasons hot sleepers live in this set.
Cool-touch knitCool to the touch, all night.
Woven from a cooling stretch knit that pulls heat away from your skin and breathes with every move. It feels cool the second you put it on and stays that way through the night — no more waking up hot and tangled in damp sheets.
Four-way stretchSofter than your favorite tee.
The fabric stretches four ways and moves with you, with flat seams that never dig in. It is the kind of soft you forget you are wearing — light enough to sleep in, polished enough to lounge and run errands in.
Machine washableMade for sleep. Worn all day.
Lightweight and breathable enough for all-day wear, gentle on sensitive skin, and fully machine washable — no special care, no shrinking. Sleep in it, lounge in it, live in it, and toss it in the wash when you are done.

Sleep on it worry-free
Does it actually stay cool?
Yes. The cooling stretch knit is cool to the touch and pulls heat away from your skin while it breathes — so you stay cool and dry through the night instead of waking up hot and sticky.
Is it soft enough to sleep in?
Incredibly. It is butter-soft, four-way stretch with flat seams that never dig in — the kind of soft you forget you are wearing. Light enough for the hottest nights, smooth enough to lounge in all day.
Can I wear it during the day too?
Absolutely. It is lightweight, breathable and looks polished enough to wear well beyond the bedroom — lounging, errands, travel. Made for sleep, but you will live in it.
Which size should I order?
Match it to your mattress — Twin, Twin XL, Full, Queen, King or Cali King. If you like extra drape or share the bed, sizing up one is a popular choice.
Can I machine wash it?
Yes. Machine wash cold, tumble dry low. It holds its shape and softness wash after wash — no shrinking, no special care.
What if I don't love it?
You get a 30-night sleep trial. Sleep under it for a month — if it's not the coolest, comfiest set you have owned, send it back for a full refund, no questions asked.
Cloud-like comfort is just a
click away. Try mellow.
