The Zeal is an essential lightweight mountaineering/ski jacket made from Gelanots technical fabric.

Gelanots® is Earth Sea Sky's high tech, waterproof breathable fabric. It breathes via a molecular transfer of moisture through a non-microporous hydrophilic membrane. It is very light and has an extremely soft handle for a laminated three layer (mesh backed) fabric. The outer surface of the fabric has a durable, water repellent finish to enhance breathability, repel stains, and prevent the outer surface of the fabric getting waterlogged.

All Earth Sea Sky Gelanots® jackets have watertight double flaps over the front zip, seams guaranteed to a 3PSI pressure test and fabric lined external pockets that prevent water coming in contact with the wearer. No compromise is made in the assembling of these garments to obtain a complete watertight construction.
