Umisleep Silk Bonnet 22 Momme

If long or thick hair shifts around while you sleep, a roomy bonnet can help keep it contained without relying on a tight, one-size cap. The Umisleep silk-lined bonnet pairs a mulberry silk interior with a satin exterior.

Its adjustable band is meant to help you set a comfortable fit and keep the cap in place overnight.

The generous shape is designed for several hair textures and styles, though it may feel like too much bonnet if your hair is short and low-volume.

Best use cases

This sleep cap is aimed at people with mid-back to waist-length hair, including straight, wavy, curly, braided, or loc’d styles, as well as men with chin-to-shoulder-length curls, locs, or Afros. The larger interior gives you room to tuck hair inside rather than compressing it into a smaller cap.

Picture winding down with braids or curls, placing all your hair inside, then adjusting the band before you turn in. The smooth silk lining is intended to reduce friction against hair and help limit moisture loss, dryness, and breakage. Those are useful goals for an overnight hair routine, but the bonnet is not a substitute for a hair-care routine tailored to your needs.

Product specs

The interior is 100% 6A-grade mulberry silk at 22 Momme, while the outer layer is durable satin. The product description lists an outer diameter of 14.2 inches, a height of 9.8 inches, and a fit for head circumferences from 21.5 to 27 inches. It also states that the silk is OEKO-TEX STANDARD 100 certified.

A soft, wide elastic edge and adjustable buckle let you change the tension. For the intended fit, the instructions say to tuck your hair inside with the buckle facing outward, pull the strap until comfortably snug, and tuck away the extra strap. The listed fit range on the spec sheet is helpful for judging sizing, but it does not guarantee the same feel for every head or hairstyle.

Where it shines

The two-fabric construction gives each side a different job: the silk lining sits against your hair, while the satin exterior is intended to help protect the pillowcase from hair products and natural oils. That makes it more purpose-built than a basic cap with no silk lining, especially if reducing friction is a priority. The adjustable buckle also gives you more control than a fixed elastic edge, though comfort overnight will depend on how snugly you set it.

Would a larger cap be useful if your hair needs room rather than compression? For longer styles, that extra space is central to the design. The gift box is another practical detail if you’re choosing it as a hair-care present, but the main reason to consider it is the lined, adjustable sleep-cap setup.

Should you buy it?

It’s a great fit if you want a silk-lined bonnet with room for longer or fuller hair, and you value an adjustable band over a fixed-fit design. It may not suit you if you have short, low-volume hair: the product description specifically notes that the oversized shape can feel too large in that case.

Choose this bonnet if the silk interior, roomy shape, and customizable tension match your nighttime routine. If you only need a simple cap for short hair, its extra space and layered construction may be more than you need.
