The Alpinestars Protean Trouser in classic Black is a versatile and essential piece for any rider tackling commuting or touring. As a leading UK retailer for Alpinestars, Moto Central is proud to offer these high-performance trousers. Equipped with a DRYSTAR membrane and a removable thermal full liner, the Alpinestars Protean Trousers are designed to handle various wet and cold weather conditions. Pre-curved leg construction and stretch panels provide excellent freedom of movement, while adjustable internal knee protectors offer class-leading safety.
Constructed from a multi-fabric poly-shell, these trousers offer an optimal combination of durability, protection, and lightweight comfort. Class-leading impact protection is provided by removable CE-certified knee protectors, housed within internal mesh pockets that can be adjusted for leg length. Pre-curved legs and an articulated knee construction enhance comfort, while stretch panels on the crotch and knee improve freedom of movement. The Protean trousers deliver all weather comfort.
Excellent protection against the elements is provided by Alpinestars' DRYSTAR 100% waterproof and breathable liner. The removable thermal liner ensures high levels of comfort in cooler conditions. Internal hip compartments are lined with ergonomically tapered PE comfort foam for superior riding comfort. A waist connection zipper allows attachment to selected Alpinestars leather and textile jackets. Integrated high-visibility reflective detailing enhances rider visibility in poor light.
