ECCO has created exceptional water resistant leather. Hydromax™ is the generic name given to ECCO leather with high water resistant properties. The hydrophobic compound generated as part of the tanning process is distributed throughout the leather structure, not just a surface effect. These leathers are also characterized by a low water uptake in wet conditions.

ECCO is one of the first major shoe companies to use Yak leather. Yak leather is three times stronger than normal cow hide. Since Yak is so much stronger, it allows us to make shoes with lighter, thinner uppers that provide more breathability and excellent climate control.
