Sea to Summit’s Towels are made of knitted microfiber fabric.
In the AirLite and Pocket Towels, this fiber is 100% Polyester.
In the DryLite and Tek Towels, the fiber is a blend of 70% Polyester and 30% Polyamide (Nylon).
The four types of towels have different weights and finish to ensure that you can dry off no matter where you are. The AirLite Towel is made of a featherweight material and is incredibly compact. The Pocket Towel is super-light and has the silkiest finish. The Drylite Towel is a medium weight and has an ultra-suede-like finish. The Tek Towel is the heaviest and most absorbent and has a terry loop-like finish, like most normal towels.
