Why Lilysilk only 22 mm silk sleepwear

Although 19mm and 22mm silk pajamas have a lot of in common as they both belong to silk product, there are some evident difference you should know.

- Wear & Tear resistance: 19 momme silk is considered to be the entry level of high-end silk and is fairly resistant to wear and tear. However, unlike bedding linen, pajamas and other nightwear are subject to much more usage (and washes), and as such, we find that the old 19 momme silk simply was not able to satisfy our original intention for it to last up to 10 years, while the 22 momme line is easily capable of doing so.

- Durability: Similar to the point above, but slightly different. While wear and tear resistance is definitely part of the overall durability criteria, the durability in this case refers to the fabric's ability to withstand casual or accidental mistreatments that happen on a fairly frequent basis. It is not rare for our products to be mistakenly thrown into the wrong washing cycle, washed with the wrong materials/detergents, dried with a drying machine for hours on end, etc., and a lot of the times the owners don't really realize that they might have used the wrong method. 19 momme silk is considerably weaker in its ability to deal with these occurrences when compared with its 22 momme counterparts. [more on this later]

- Fabrics Aging: Silk fabrics age over time and become dull, and there are a number of factors that help determine the speed at which this aging process happens. Some of the most notable factors include washing frequency, water quality, amount of usage, and one factor that is often overlooked is fabric density. Lower quality silk such as the one used in women's lingerie can easily become dull after a few washes, whereas 19 momme silk generally starts to lose its original shiny exterior after 5-6 months of usage. 22 momme silk however, can last up to 2 years before you start to notice that it has started to dull.

In the end, we just feel that the old 19 momme sleepwear line did not suit our overall image of a high-end silk seller. Our goal is to sell products that are not only comfortable and healthy, but also durable and long lasting. The 22 momme upgrades are much more aligned with our purpose in this case.
