How protective are these jeans?
They carry AA Class CE certification. Knee and hip protection comes from 10 mm Nucleon Morph STEALTH Level 2 pads that contour to the body, so the armour stays slim under the denim.
Do they look and feel like normal jeans?
Yes. Single-layer A-TRAACX technical denim means no separate liner, and the traditional five-pocket design, metal zip fly and regular straight fit look at home off the bike. Hidden dual seams and overlock stitching keep the outer legs clean.
Will they stay comfortable in Indian heat?
COOLMAX yarn in the denim wicks moisture away from the body to help keep you cool and dry in warm or changing conditions, and the stretch construction keeps you mobile on the bike.
Can I adjust the knee armour position?
Yes. Three knee protector pocket positions, spaced 3 cm apart and marked by colour-coded stitching, let you set the pad height so it stays over the knee when seated.
