The most popular topper is Cotton Jersey, it wicks fast and is dry to the touch. 

 Minky is a marmite fabric, you either love it or hate it.  I love it!  It’s a furry polyester fabric, its stays dry and wicks fast.  As it is man made it never stains and looks like new when its years old.

 Bamboo Velour is a furry natural fabric, it has an absorbent quality to itself and is one of the more popular topping choices.
