Mulberry Silk Pillowcase 25mm King - Cool, Hair-Friendly Sleep

Our review of the Mulberry Silk 25mm King pillowcase finds it best for people who want a chilled, hair-friendly surface and premium fabric without unnecessary fuss. The single biggest reason to buy is the fabric quality: this pillowcase is made of 100% long strand, Grade 6A Pure Mulberry Silk on both sides, which delivers immediate softness and noticeable hair protection. It feels cool to the touch, is OEKO-TEX STANDARD 100 tested for harmful substances, and includes a generous envelope flap that keeps a king pillow securely inside.

Key Features

• 100% Mulberry Silk: Offers a smooth sleeping surface that reduces friction and helps protect hair from breakage and frizz.
• 25mm momme density: A higher-weight silk that feels substantial and durable while still draping elegantly over the pillow.
• Certified and tested: OEKO-TEX STANDARD 100 testing coverage reduces concerns about harmful substances and supports safer textiles.
• Silk on both sides: The pillowcase is finished with silk inside and out so both faces deliver the same cooling, gentle feel night after night.
• Oversized envelope flap: A slightly offset side entry and extra flap keep the pillow securely enclosed and allow the case to function as a sham.
• Easy care options: Can be hand washed, dry cleaned, or machine washed on gentle using a mesh bag, then laid flat to dry for simple upkeep.

Who It's For

This pillowcase suits sleepers who prioritize skin and hair health and want a cooler night surface; anyone with sensitive skin or hair that tangles or frizzes will notice an immediate difference. It is also a good match for buyers who value certified textiles and prefer long strand Grade 6A silk for both feel and durability.

Shoppers seeking budget microfiber or very high-momme silk may want to look elsewhere, and those who need daily machine tumble drying should consider a different fabric since the recommended care is hand wash or gentle cycle and flat drying to preserve the silk.
