This updated version of the Zephyr GTX Hi is stronger, more technical, more durable and even higher-performance than the original Zephyr GTX Hi. Standout features include tear-resistant split leather/Cordura® upper, a locking ankle eyelet, a lace holster, instep protection against rope abrasion while fast-roping, and a new slip, heat & fuel-oil resistant outsole. All in a tall shafted version for extra protection and support and EU PPE certified. Durably waterproof/breathable.
