Type of membrane

The “Type of membrane” specification indicates which brand of membrane is used in the jacket, if present (not all motorcycle jackets contain a membrane; this specification does not apply to jackets without one). The membrane determines how waterproof and windproof the jacket is, and also affects breathability. Well-known membranes such as Gore-Tex offer an optimal balance between rain protection and comfort while riding. Additionally, the construction of the membrane can be specified, which affects weight, durability, and wearing comfort.

• 2-layer (2L): the waterproof membrane is laminated onto a carrier. A removable lining (mesh or nylon) protects the membrane and provides extra comfort. This construction is flexible and comfortable, but generally a bit heavier and less breathable than 3-layer.
• 2.5-layer (2.5L): the membrane is laminated onto a carrier and finished on the inside with a thin protective print or coating instead of a full lining. This results in a lightweight, compact construction that offers excellent rain protection, but usually less durable than 3-layer.
• 3-layer (3L): the membrane is bonded in a “sandwich” between a carrier and a durable, lightweight inner layer. There are no loose layers. This is the most robust, durable, and breathable construction, ideal for intensive use and harsh weather conditions.
• Z-liner: the membrane hangs freely between the outer material and the inner lining and is not laminated. It is secured at several points within the jacket. This construction is flexible and comfortable, but the outer material can absorb water, making the jacket heavier during prolonged rain.
