6 Layer of 250 gsm bamboo terry in a snake style bifold insert.  This will fit comfortably in our Maximest sized pockets and can even fit in a Middlest pocket if folded over three times.  
Bamboo terry is a pliant, soft and extremely absorbent material.  These are slightly longer than 32” after being washed 3 times in warm water and dried on warm. Minimal shrinkage is expected due to material composition. 
This listing is for a single insert.
