TheWashDay editorial · Updated · From the makers’ own pages · How we compare
A bonnet or cap keeps your curls in a smooth fabric all night; a silk or satin pillowcase does the same for the side of your head that ends up on the pillow. These eight are compared by what their makers publish: fabric and silk weight, fit and closure, and how to wash them. Silk is a natural fiber; most satin is a weave of polyester, though Kitsch and Grace Eleyae don’t say what theirs is made of.

Bonnets, caps, wraps and pillowcases whose makers publish their fabric, fit and care, from the makers’ own US pages. We haven’t used or tested them, and commissions never change the list or its order.
Silk or satin, and what “22 momme” means
Silk is a fiber; satin is a weave. The four silk pieces here (Slip, Blissy, Mulberry Park and SILKE London) all give 22 momme mulberry silk, grade 6A: momme is the silk’s weight, and 6A the grade of its fiber. The satin ones (Kitsch, Grace Eleyae) don’t name their fiber, so you can’t compare them on paper beyond the weave and the care.
Satin goes in the wash more easily: Kitsch’s pillowcase is the only piece here you can tumble dry, on low. The silk makers want a cool, gentle wash in a mesh bag or by hand, and no tumble dryer.
Grace Eleyae’s Slap is a cap lined with charmeuse satin, held by an elastic band, in sizes M-Original and L; its Adjustable Slap adds hidden drawstrings, and Grace Eleyae calls it the rough sleepers’ go-to. Grace Eleyae suggests putting your curls up in a pineapple first. Kitsch’s Oversized Satin Bonnet is double-layered with extra-long ties, made for thick 4C curls or long hair.
Mulberry Park’s Long Hair Reversible Bonnet is 12 x 24 inches with a silk band, elastic at the back and two ribbon ties, for heads about 20 to 25 inches around; wear the shiny side in. SILKE London’s Silk Hair Wrap Bonnet adjusts from XS to XL with an elastic headband and a slider; for long, thick or textured hair, SILKE says to tie it up first.
Pillowcases: check the inches, not the size name
Slip’s and Blissy’s pillowcases are 22 momme mulberry silk with a hidden zipper; Kitsch’s is 600 thread-count satin with a zipper. Size names don’t match between makers: Blissy’s Standard fits 20 x 26 inch pillows, Slip’s Queen is 20 x 30 inches and Kitsch’s Queen/Standard is 26 x 19 inches, so measure your pillow.
A pillowcase helps whichever way your hair falls, but only on the side that touches it. Blissy suggests a loose braid or a loose bun on top of your head, held with a silk scrunchie, if you sleep on it without a bonnet.
What this comparison does and doesn’t claim
We haven’t used these bonnets and pillowcases; we compare what their makers publish. This isn’t a ranking, and we make no claim that silk or satin prevents breakage or frizz. Certifications such as OEKO-TEX are named as each maker names them. We don’t show prices on this page yet; each maker’s page has its current price.
Questions before your next wash
Is a silk bonnet better than a satin one?
Silk is a natural fiber and satin is a weave, usually of polyester. The silk makers here give the silk’s weight and grade; the satin makers don’t name their fiber. Both are smooth; silk needs gentler washing.
Do I need a bonnet if I have a silk pillowcase?
Not necessarily. A pillowcase protects the side of your head on the pillow; a bonnet keeps all your hair in fabric, which also holds a pineapple or a protective style in place.
