I sweat a lot, do you have any advice for futon bedding?

Some fabrics are airly and easy to dry, such as "Takashima chijimi" and " Odawazarashi". So they are recommendable when you choose futon fabric.
Also, using Tatami underlay and futon dehumidifying sheet are advisable.
We listed some more recommendable items at "For climates above 77℉(25℃)", so
please check them.
