Cortech Hyper-Flo Air Pants The Hyper-Flo Air Pants from Cortech are a mesh riding pant with the warmer months in mind. The big panels of mesh at the upper leg and back of knee make it easy for fresh air to flow in an and out, boosting comfort and reducing fatigue. At the same time, key impact areas are given added reinforcement, and the entire chassis is held together using tough 600D polyester. The pants arrive with CE Level 2 knee armor in place and pockets can accept optional hip armor (sold separately). Cortech includes a full length rain liner that is worn under the Hyper-Flo Pants' outer shell. As temperatures drop, add this rain barrier to help increase the pants' thermal properties. The Hyper-Flo Air Pants can pair to the Hyper-Flo Air Jacket or other Cortech jackets with connection zippers. Almost any jacket can be modified to accept these pants using the DIY connection zipper hardware that these pants include in the box.  Features: Abrasion resistant 600D polyester shell Large mesh panels at thigh and back of knee Abrasion resistant 1000D nylon dobby on knees and seat Full length zip-out waterproof rain liner Included CE Level 2 Safe-Tech knee armor Pockets for optional hip protectors (sold separately)   Hook and loop waist adjustment Dual button zippered fly rain closure Zippered ankle closures with hook and loop adjustment YKK zippers Reflective trim at ankles Includes 8” pants to jacket zipper attachment with jacket-side zipper hardware included
