Unbeatable, flexible, durable and lightweight - this is how the race team tested and proven pant presents itself. The 5.5 pants offer ultimate comfort and protection. A completely new fit with an anti-slip system at the waist that hooks into the rear gusset so the pants don't slide down! The full-grain leather knee panel offers ultimate abrasion resistance and is part of our multi-layer Internal Knee Brace System (IKS), which reduces wear and tear on knee pads made from other materials in critical areas without compromising comfort and feel.
