How we assessed this productResearch-based review · No hands-on testing
This is a research-based editorial assessment of the specified product. We checked current manufacturer information, care and return terms, and relevant third-party coverage. We have not conducted hands-on testing, placed a test order or assigned a measured performance score. Manufacturer demonstrations and external reviewers’ observations are attributed. The source record was checked on 5 September 2026 and can be updated with future testing notes.
Ecosa is worth a look if you specifically want a heavier silk specification. The current US page is clear that this is a 30-momme pillowcase, which separates it from the lighter models in the list. That number is a starting point, not a comfort score: more silk weight does not automatically mean the best temperature feel or the right fit for every person. The more consequential buying detail may be the restricted return policy.
What you are buying
The US product page lists Grade 6A mulberry silk in a charmeuse weave, silk on both sides and a 50 × 70 cm Standard size. Do not assume that “Standard” matches a US 20 × 26-inch case or a 20 × 30-inch Queen. Measure your actual pillow. The accessible specification does not clearly identify the fastening, so we leave the closure unconfirmed rather than infer it from a photograph.

What the available evidence tells us
Ecosa’s FAQ explicitly distinguishes the current 30-momme product from an older 25-momme version. Some online coverage and Australian owner comments concern other regions or generations. We have not treated those anecdotes as a measured US defect rate or used an old specification for this listing. We also have not conducted an independent temperature or wash-durability test of the current case.
Care and everyday ownership
The care instructions specify a cold, short, gentle wash with suitable mild detergent and air drying away from heat and sunlight. Tumble drying, bleach and disinfectants are excluded. A heavier silk specification does not remove the need for gentle care. If that routine is inconvenient, choose a material that better suits your laundry habits rather than expect the fabric weight to compensate.

Before placing an order
The pillowcase FAQ makes an important exclusion: Ecosa’s 100-night trial does not apply, and the case cannot be returned for change of mind. It instead has a 45-day warranty against defects, with the stated remedy handled under those conditions. Those are different protections. Check the size carefully and clarify any uncertainty before placing the order.
How it compares with the shortlist
Choose Ecosa when you deliberately want the heavier specification and are comfortable with the fit and purchase restrictions. Blissy remains our overall choice for the complete offering. Quince and Mulberry Park are useful alternatives if a lower initial spend is more important; check their different return conditions individually. We would not make a decision on momme alone.

A few more things to know
Does Ecosa’s 100-night trial cover this pillowcase?
No. The pillowcase FAQ specifically excludes it and says change-of-mind returns are not available.
Is the current US version 25 or 30 momme?
The current US listing and FAQ specify 30 momme and identify 25 momme as the older version.
Will it fit a US Queen pillow?
The stated case size is 50 × 70 cm. Compare those measurements with the actual insert; do not rely on the word Standard alone.
