Alpinestars Juggernaut Waterproof Pants – Black

The alpinestars Juggernaut Waterproof Pants are black waterproof motorcycle trousers with a 3L softshell construction and waterproof membrane. They are described for urban and commuter riding.

Level 1 Nucleon Flex Plus knee armour is fitted, with a calf volume adjuster to help keep it positioned while riding. Level 1 Bio-Flex hip protectors are available as an optional accessory upgrade. The trousers have direct thigh ventilation openings, two zippered cargo pockets, a YKK zip and hidden snap button on the front flap.

An elasticated waist with a pull string adjuster, stretch rib fabric at the waist and an elasticated ankle cuff are included. The back section is elongated for coverage in the riding position. The garment is CE Category II to prEN17092 draft standards, A Class; the knee protectors are CE Level 1 EN1621-1:2012.

The UK waist sizing guide gives S as 30 with a 31-inch length; M as 32 with a 31-inch length; L as 34 with a 32-inch length; XL as 36 with a 33-inch length; 2XL as 38 with a 34-inch length; 3XL as 40 with a 35-inch length; and 4XL as 42 with a 33-inch length. Alpinestars garments may fit smaller than other brands, so sizing up from a previous motorcycle trouser may be needed to allow for the thermal liner. The guide cannot determine an exact size.
