Key Features:

Featured Fabrics

• DIAMOND Ultra is a proprietary 2-layer softshell with premium breathability, waterproofing, elasticity and stormproof protection. Used in twinDeck layering with OSMOS Light for insulation and freedom of movement.

• A lightweight waterskin ankle wrap sealing the lower legs from spray and wind chill.
• RS S11 insert that has a 9mm Shock-Absorb Damping System Mono platform with thermoformed shaping for friction-free comfort
• 3D waffle is a three-layer perforated foam that boots breathability and reduces bulk.
• KraterCooler ventilation that expels heat and moisture, preventing chill from trapped dampness.
