This is a question we receive a lot.
There are two very common varieties of fabrics used to create dakimakura cover: peachskin and two-way tricot, seen in the image below:
The simplest way to explain the different would be that peachskin is an inelastic, durable, satin-like polyester material with a slight fuzz to the surface, while tricot is an elastic and smooth polyester-spandex blend. Peachskin covers are cheaper while tricot ones are more expensive, as this reflects the cost and quality of the materials. While peachskin tends to be roughly the same between manufacturers, two-way tricot can very widely by cost and quality.
There are many different varieties of two-way tricot you will find around the web from different dakimakura cover sellers. The highest quality materials are from manufacturers in Japan. Our current covers feature a two-way tricot produced by A&J, a well-known manufacturer of dakimakura covers in Japan. Our previous lower-end tricot covers were made using a generic Chinese two-way tricot. They are currently still available in our bargain bin section.
IMPORTANT NOTE: While peachskin is often associated with bootleggers, all of our designs are original. We do not sell our designs on any other site than this one and our Etsy store. If you see our designs being sold elsewhere (eBay, Aliexpress, etc), these are not official.
