CUT
This jacket has a feminine fitted cut. The fabric, which contains 13% elastane, has the stretch you need for even more freedom of movement when hiking. A warm layer such as a fleece or lightweight down jacket may be worn underneath.
You can choose your usual size, or one size up if you prefer a less fitted cut.
HOOD
The height and depth of the attached hood can be adjusted using an elasticated drawcord. Rigid visor for maximum face protection.

Your MH500 jacket has a so-called "3-layer" component.
Indeed, a membrane is stuck to the inside layer and the outer layer of the component, which is why it is referred to as a 3-layer component. This construction helps the membrane last longer and enhances the component's performance.
