These preflats are made up of 2 layers of cotton hemp surrounded by a pretty cotton lycra print.
Inside is a sewn in snake insert, which is made with 2 layers of bamboo and topped with bamboo velour.
These preflats are a great day or night time solution. There are a number of different ways to fold the preflat, and when paired with a cover they are a super trim option. Because they open out, it makes cleaning easier, and drying faster.
This is a fantastic pre flat! I pre washed three times and it then did 13 hours over night. It will dry in a day/overnight if you put it on the radiator or a heated rail. I definitely think that these are worth the money.
