Frequently asked questions Hide FAQs
How should the Supertech Foster Pants fit, and which size should I choose?
The Supertech Foster Pants have a rider-engineered performance shape for motocross movement, with a stretch rip-stop chassis and strategically positioned four-way stretch panels. The double-overlap hook-and-loop waist closure and ratchet system adjust the waist fit, while silicone printing inside the waist helps hold the pants in position.
The Black variant is listed in sizes 28–40, in two-size increments. Compare your measurements with the Alpinestars size guide and check the fit in your riding position with your intended knee protection and MX boots.
Can I wear knee braces or knee guards under the Supertech Foster Pants?
Yes. The Supertech Foster Pants feature a liner-less design and an overlock flat-seam interior to support comfort and easier on and off when wearing knee braces or knee guards. Their 3D leather knee panels, backed with stretch aramid reinforcement, are designed to work with knee braces for riding feel, grip and control.
Check the fit with your own knee protection to ensure you can bend your knees and move freely in the riding position.
How do the Supertech Foster Pants ventilate during hot-weather motocross riding?
Open mesh inserts channel cooling air into the hip area and allow warm air to exit at the rear. Stretch mesh at the back of the knees and lower legs adds airflow and flexibility when wearing MX boots.
The lightweight, liner-less construction supports comfort during active motocross and Supercross riding without an additional internal lining.
What materials reinforce the Supertech Foster Pants at the knees and seat?
The Supertech Foster Pants combine an advanced stretch rip-stop chassis with 600 Denier seat reinforcement and dual-layer 600 Denier knee panels for durability in key wear areas. Strategically positioned four-way stretch panels support freedom of movement.
At the inner knees, heat-resistant stretch aramid reinforcement and 3D leather panels backed with stretch aramid reinforcement provide localized heat resistance, durability and grip. These construction features are designed for motocross use; they do not indicate a CE impact-protection level.
