JT Racing USA Classick MX Pants (Yellow/Black, Size 28) JT Racing's Air Line System (ALS) dual air intake vents are positioned mid-thigh (so theyre not blocked by knee braces) and feature a venturi effect for positive cooling when in motion and while stopped Articulated 360-degree knee design with multi-directional flex, 1680 denier ballistics construction for durability and maximum abrasion protection, hand-formed and hand-cut padding, and plenty of room for a knee brace Straight-leg fit; MX riders stand most of the time (or should), so the Classick is cut to reflect that; the result is more comfort and a better fit High-back waist means a more secure fit at the waist, improved jersey retention, adjustable lower-back support and low-spine impact protection, thanks to a 10 millimeter thick pad Kodra 600-denier Inner-leg fabric; a rider's butt and inner thighs are prone to severe abrasion and wear while riding; use of super-strong Kodra material here makes this a non-issue
