Cotton is a rough, absorbent fabric — it grabs at hair strands, strips moisture, and creates the friction that turns a fresh blowout into a frizzy mess overnight. Satin is the standard solution: the smooth surface glides against hair instead of grabbing it, preserving the style, the moisture, and the work you put in. The WRAP is a satin sleep bonnet with an adjustable tie-band — it stays on through the night, fits a range of head sizes, and comes in 16 colors so you can choose one you'll actually want to wear.
Satin glides. Cotton grabs. Your hair knows the difference.
- SATIN-SMOOTH — THE FRICTION DIFFERENCE: cotton pillowcases have a rough surface texture that grabs hair fibres with every movement during sleep — creating friction that causes breakage, frizz, and moisture stripping. Satin's smooth weave glides against the hair shaft without resistance. The same hair, the same sleep, a different outcome.
- ADJUSTABLE TIE-BAND — STAYS ON ALL NIGHT: the tie-band is adjustable to fit a range of head sizes and sits firmly enough to stay through normal sleep movement including tossing and side-sleeping — without leaving forehead marks from over-tightening. Unlike elastic-only bonnets that loosen or slip off by morning, the tie closure maintains its hold through the night.
- CURL & PROTECTIVE-STYLE SAFE: natural hair loses moisture rapidly against absorbent cotton — WRAP's satin surface locks in moisture and protects the style underneath. For braids, twists, and locs, it prevents the frizz and distortion that come from surface friction during sleep. Your wash-day work survives the night.
- 16 COLORS — ONE FOR EVERY MOOD: Champagne, Rose, Sand, Sky, Sunset, Plum, Magenta, Bone, Lilac, Mocha, Indigo, Ruby, Sage, Blush, Royal, Onyx — sixteen colors across warm neutrals, soft pastels, and deeper tones. Not a one-color-fits-all sleep accessory; a bonnet you'll actually want to wear because it matches how you think about the rest of your sleep space.
Mechanical friction from cotton pillowcases is a primary cause of hair breakage, split ends, and overnight moisture loss — particularly for natural and chemically treated hair.

Why overnight friction damages hair — and how satin stops it
Each movement during sleep drags hair against the pillow surface — cotton creates significant friction that slowly fractures the hair shaft. Over weeks and months, this causes split ends, breakage, and thinning at the points of highest contact. Satin's smooth surface removes the friction without removing the movement.
Frizz is mechanical damage to the hair cuticle — roughed-up cuticle scales that catch light at random angles and absorb atmospheric moisture unevenly. Cotton pillowcase friction is a direct cause of cuticle damage during sleep. Satin preserves the cuticle alignment that keeps hair smooth.
A blowout, a protective style, or a curl pattern can survive the night in a satin bonnet intact — the same style that a cotton pillowcase would destroy through friction. The satin creates a protected microenvironment around the hair for the full sleep cycle.
For anyone whose morning hair tells the story of what their pillowcase did overnight.
The blowout preserver
You got a blowout, went to sleep, and woke up with it half-destroyed. Cotton took the friction-cost out of your styling investment overnight.
WRAP's satin surface lets the blowout survive the night — the same smoothness, the same volume, the same work preserved through 8 hours of sleep.
The natural hair maintainer
Natural hair loses moisture rapidly against absorbent cotton — frizz, shrinkage, and breakage accumulate every night you sleep without protection.
Satin locks in moisture and removes friction. The moisture your hair had when you went to sleep is still there in the morning. Wash-day work survives the week.
The protective-style wearer
Braids, twists, and locs lose definition and develop frizz from nighttime friction. The front edges are the first to go.
WRAP protects the full style — the bonnet covers braids and locs while the satin surface keeps the edges and perimeter frizz-free.
The frizz-prone sleeper
You don't have a particular style to protect — your hair is just frizzy every morning regardless and you've accepted it as your default.
Most morning frizz comes from overnight friction. Replace cotton with satin and the frizz doesn't return after the first morning — it doesn't form in the first place.
The gift-giver
You want to give something genuinely useful that the person would use every single night — not something that gets put in a drawer after week one.
WRAP is the sleep accessory that delivers visible results within the first morning. 16 colors to find the right match. Practical, beautiful, nightly value.
Tie it on. Wake up with your hair intact.
Gather Your Hair
Gather your hair loosely before bed — for longer hair, a loose bun or gathered ponytail at the nape works best. For shorter hair or wash-and-go styles, wear it as-is.
All Hair LengthsPlace and Tie
Place the WRAP over your hair and adjust the tie-band for a comfortable, secure fit — snug enough to stay through sleep, loose enough not to press against your forehead. The satin interior sits directly against your hair.
Adjustable Tie-BandWake Up, Untie, Go
In the morning, untie the band and remove the bonnet. Your hair is protected — the blowout preserved, the curls intact, the frizz that was coming from overnight friction simply absent.
