Nice concept but many issues.
Nice concept but the product feels unfinished. Both sets I bought had quality control issues: one had loose threads hanging in several places, and the other had a large blue stain on one pillowcase that could not be washed off. After about 10-15 washes there is considerable bobbling on the fabric which is unexpected as it is synthetic.
The material is labelled as microfibre, but it isn't clear exactly what material it is. I have found that it holds smells very strongly, which cotton blends and cotton sheets do not.
I am not sure what their expected lifespan will be, given the few issues I have had. I would advise that they need washing twice a week due to their propensity to absorb smell if you get even slightly sweaty in them or wear any sort of skin lotion/deodorant/scented product. However this clearly has an impact on the material and they are no longer nice and smooth despite being laundered separately.
They also have a propensity to become extremely static which became a big problem for me as my hair would always be static because of the sheets.
