The versatile K5 - Modus Jacket works hard to take care of you both inside and out. The key is our unique performance fabric crafted from bamboo charcoal yarn. Highly technical, lightweight, and eco-friendly, bamboo charcoal yarn combines moisture management, thermal regulation, and odor reduction in a single package. Paired with a tough double-weave softshell, a durable water repellent (DWR) finish, and a hood, the Modus keeps you feeling comfortable, fresh, and dry throughout active use in a variety of environments.
Amazing how something so lightweight can keep you warm. It is designed to move heat/moisture away from your body during high intensity activities and trap heat when less active. If windy, a shell would be needed as it offers no wind resistance but, it doesn’t claim to be wind resistant as that’s not its design purpose.
