The body of  Boxair is made of high quality combed cotton.
Combed cotton is extremely soft version of the traditional cotton, made by special treatment of the cotton fibers before being woven into yarn.
The texture of combed cotton is softer because it lacks short threads to stick out and prickle. All dirt and impurities have been removed from the thread as well.

It is also stronger, because shorter and brittle fibers have been removed through the process of combing. In addition, the straightened fibers lie together more tightly, making combed cotton thread less likely to fray and unravel.
