ALASKA BEAR Natural Silk Pillowcase: Hypoallergenic Mulberry Silk, 19 Momme, Dark Purple (50x75 cm) with Hidden Zipper
Product description
What it is
This ALASKA BEAR pillowcase is crafted from 100% Mulberry silk, rated at 19 momme, and features a hidden zipper for a tidy finish. It’s designed to be soft, breathable and hypoallergenic, aimed at protecting skin and hair while you sleep. The dark purple colour adds a subtle, sophisticated touch to a bedtime setup, and the standard size (50x75 cm) is intended to fit many UK standard pillows. The fabric is OEKO-TEX certified, ensuring it’s free from a range of toxic substances.
Why it matters

On the surface, silk feels cool and smooth against bare skin. On a practical level, silk pillowcases reduce friction compared with cotton or linen, which can help minimise morning creases, dry skin and tangles in hair. For anyone worried about sleep-related skin or hair concerns, this is a low-friction alternative that doesn’t rely on synthetic coatings or heavy treatments.
What stands out
- Premium 19 momme double-sided silk for a soft, luxurious feel with durability.
- Pure Mulberry silk with a relatively low environmental footprint compared with some other fibres.
- Hidden zipper keeps the pillow in place and presents a neat finish, reducing slippage during the night.
- Hypoallergenic and breathable, with dermatological benefits often cited for silk pillowcases.
- OEKO-TEX certified, offering reassurance about chemical safety.



What may hold it back
- It is not a one-size-fits-all solution, people with very thick or unusually large pillows may need to check fit beyond the stated standard size. If you prioritise a cotton feel, silk may feel distinctly different to the touch and may require a familiarisation period.
- While silk is durable, it still requires gentle care. Washing and drying instructions matter to preserve the fabric’s integrity and sheen.
- The colour (Dark Purple) may show light markings or colour transfer with certain fabrics or skincare products, so consider pillow protection or laundering patterns.
Who it’s for

This pillowcase suits those seeking a skin-friendly, hair-conscious sleep surface without harsh chemical treatments. It’s a practical option for anyone aiming to reduce hair frizz, breakage, or pillow creases in the morning, and who appreciates a premium material with a calm, understated colour.
Who it isn’t for
If you’re after a cotton-feel tactile experience or a price-first option, this silk pillowcase sits in a different tier. For pillows that require a stronger, more rugged fabric, or for users who prioritise machine-washable fabrics at very low temperatures, there might be more budget-friendly or robust alternatives.



When it makes sense to buy
If your goals include kinder treatment for skin and hair, cooling comfort, and a neat finish at night, and you’re comfortable with the care instructions silk requires, this pillowcase can align well with those needs. It’s also a reasonable pick if you already value OEKO-TEX safety and natural materials.
When to pass on it

If you frequently wash at high heat or need a pillowcase that’s extremely budget-friendly, or if you need a non-zippered, ultra simple cover, this might not be the best fit. Also, if you own a non-standard pillow shape or size, confirm compatibility beyond the stated 50x75 cm.
What to review before buying
- Confirm pillow size: 50x75 cm aligns with many UK standard pillows, but verify your own pillow’s dimensions.
- Check wash care: silk typically prefers gentle cycles, cooling settings, and air or low-heat drying to maintain texture and sheen.
- Consider the colourfastness with your skincare products or night-time routine, to avoid colour transfer or staining.
- Look at the zipper finish and interior stitching, a well-finished zipper helps prevent pillow loss during sleep.



Practical use case
Imagine swapping your cotton pillowcase for this silk option after a long day. The surface feels cool, almost slick, as you settle down. Your hair glides rather than twists, and you wake with less morning frizz and puffy eyes. It’s not a miracle cure, but for many who sleep with a head of hair or plan to reduce facial creasing, the everyday effects accumulate over weeks.
How it compares to other approaches
If you’re weighing silk against cotton, the silk option offers a noticeable reduction in friction and moisture management. It’s a sensible middle-ground between affordable bedding and premium cotton blends. For those who already use silk and want a consistent standard size with a hidden zipper, this product provides a practical upgrade rather than a radical shift.
Final decision
Should you buy it?
Worth considering if skin-friendly, hair-protective sleep surfaces matter to you and you’re prepared to follow gentle care guidelines. It isn’t the cheapest option, but the combination of 19 momme silk, hidden zipper and OEKO-TEX certification positions it as a credible choice in the silk pillowcase category for UK buyers.
