Hydrophilic Membrane

Inside a shellTA

The ShellTA is made from a waterproof and breathable lightweight hydrophilic membrane with sufficient hydrostatic head to allow you to sit on wet ground.

This fabric has the advantage of drawing water off layers that are worn beneath – which are typically already wet by the time you pull the ShellTA on. It helps dry these layers by spreading this moisture over a large well ventilated area.
