Alpinestars Supertech Dyna Pants

Pro-level MX pants, four graphics

The Supertech Dyna Pants are Alpinestars' top-range motocross pants in the Dyna graphic: a single-layer stretch ripstop shell with an athletic cut drawn from the SX and MXGP race programme, perforations and breathable Stretchnet zones through the lower legs to keep them cool, and goat leather with stretch aramid on the contoured inner knee panels where you grip the bike. There's no liner, which is deliberate: the pants go straight over knee braces without bunching.

Sizing and fit

Waist sizes 28 to 38 in four colourways: Blue/Black/Purple, Green/Black, Purple/Pink and Red/White/Navy/Blue. It's a pro athletic race fit, so it sits close through the thigh and knee; if you're between sizes, take the larger one. The SX1 auto-locking magnetic buckle fastens fast and a silicone inner waistline stops them riding down.

Complete the set

Pairs with the Supertech Dyna Jersey in the same colourways and Supertech MX Gloves. Add an RK-7 Plasma Knee Brace or Bionic Plasma Knee Protector underneath. Kids' version: the Youth Supertech Dyna Pants.
