BYDHZN 100% Pure Silk Pillowcase 2 Pack for Hair and Skin, Both Sides 23 Momme Grade 6A+ Mulberry Silk Pillowcases with Hidden Zipper, Soft & Smooth Cooling Pillow Cases (Navy Blue, Queen 20x30) Review (2026)

Who this silk pillowcase fits

This is a 2 pack of Queen size, 20 by 30 inch silk pillowcases meant for anyone dealing with dry skin, frizzy hair or overheating on standard cotton cases. The listing specifies 23 Momme weight silk, heavier than the 19 to 22 Momme silk used in many budget silk pillowcases, which generally means a more durable, substantial feeling fabric that holds up to repeated washing better than lighter weights. Both sides of the case are silk rather than only the top layer, so the smooth surface is not lost once the case flips or shifts during the night. Shoppers who want the lightest possible silk case at the lowest price, or who do not want to handle delicate fabric care, may prefer a lower Momme option instead.

Momme grade and construction explained

Momme is the traditional unit for measuring silk fabric weight and density, and this listing states Grade 6A+ mulberry silk at 23 Momme, positioning it above entry-level 16 to 19 Momme silk pillowcases in both thickness and expected durability. Mulberry silk itself is the most common and widely regarded grade of silk used in bedding, produced from silkworms fed exclusively on mulberry leaves, which yields long, consistent fibers. The case closes with a hidden zipper rather than an envelope opening, a construction choice that keeps the pillow fully enclosed and prevents it from slipping out during the night compared to open-ended designs. The Queen 20x30 sizing is cut for larger queen and king pillows rather than the smaller 20x26 standard size, so buyers should confirm their pillow dimensions match before ordering.

Living with silk pillowcases

Silk pillowcases in general require gentler care than cotton, typically hand washing or a delicate machine cycle in cold water with a mild detergent, followed by air drying rather than high heat, to preserve the fiber's smoothness and prevent damage over time. With a navy dye, it is worth washing the case separately for the first few washes since darker dyes on silk can bleed slightly before they fully set. The heavier 23 Momme weight should hold up to this washing routine better than thinner silk, since more fiber density generally means more resistance to friction and wear. Because silk is a natural protein fiber, it also does not absorb moisture the way cotton does, which is part of why it is marketed as cooling and gentler on hair and skin overnight.

How it compares with other cooling pillowcases

In the site's cooling silk pillowcase ranking this model finishes at number 1 of 8 with our score of 8.8 out of 10, ahead of several competing mulberry silk pillowcases that come in at 7.6 or lower, including the INFIIXSO standard size case with zipper and the 2 pack Mulberry Silk Pillow Cases for hot sleepers. Most of the lower-scoring rivals in this guide do not specify a Momme weight as high as 23, or do not confirm Grade 6A+ silk, which is the detail this BYDHZN listing leads with. Buyers focused purely on price over fabric weight might still consider one of the lighter Momme rivals, since heavier silk generally costs more per pillowcase.

Verdict and who should consider something else

This pillowcase set is a strong pick for anyone who wants genuinely heavier, higher grade silk on both sides of the case rather than a thin, budget silk product, and who is comfortable with the gentle wash routine silk requires. It makes less sense for buyers who want the cheapest possible silk pillowcase or who are not willing to hand wash or use a delicate cycle. Anyone specifically shopping by pillow size should also double check the Queen 20x30 dimensions against their own pillows before ordering, since silk pillowcases in the wrong size will not stay in place properly.
