Heavy insulation that adds a layer of warmth to light shells and winter jackets alike. Stows in a pocket when the weather warms mid-ride.

The RS Winter Mid Layer simplifies four-season cycling by adding versatility to your wardrobe and eliminating the need for different dedicated jackets for the shoulder seasons and winter. Over a base layer and under a spring/fall shell, it upgrades light weather protection to a full winter jacket, trapping warmth while jettisoning internal moisture. On days when the temperatures drop, pull up the integrated face cover and hood; when the temperature or the road climb during your ride, the Thermobooster peels off to stow until clouds roll in or on long, chilling descents.

Features

• This layer’s OSMOS Heavy material is our warmest insulator, the same as featured in our S9 winter jackets and tights. It combines stretch, a soft inner face, brushed insulation, and breathability to ensure dry warmth.
• The integrated face mask is made from OSMOS Light, less insulated and a better fit under a helmet.
• Our raceFit provides a lightly compressive feel and easy layering, even under outer layers cut for aerodynamics.
