Fresh from Italy. These are the new addition to the adventure touring motorcycle clothing range from Alpinestars. They are highly vented and so they are perfect for summer riding. The main construction of the Alpinestars Ramjet Air trousers is a multifabric outer shell with strategically positioned poly-fabric stretch panels which help with freedom of movement and comfort.

The protection that you need. As well as being made with an abrasion resistant outer, the Ramjet Air trousers also feature removable CE certified knee armour to reduce the effects of impact in an accident, plus PE padding located at the hips, which can be bumped up to full-on protection with the addition of separately sold Alpinestars Nucleon hip protectors. Reflective detailing at the sides of the legs make you much easier to see when riding in poor light conditions.

The comfort you want. On top of the poly-fabric stretch panels, there are accordions at the back of the knees and back of the waist to further improve comfort. The legs are pre-curved to help reduce rider fatigue and the back of the waist comes up higher than older Alpinestars trousers to keep windchill at bay. The Jet Ventilation System on the thighs allows you to open a large flap using a combination of zip and Velcro, and secure it out of the way so that the mesh panel is open to get as much air as possible to keep you cool as you ride. The waist is adjustable with a D-Ring and secured to your size with Velcro. The ankles also have Velcro adjusters and there are two zippered hand pockets.
