The Core jacket is REV'IT!'s entry-level insulating mid layer that you can wear underneath practically every REV’IT! outer shell which doesn’t include a thermal liner, or as an insulated body warmer while off your bike. It’s highly breathable, lightweight and packable. It allows your body to retain the heat it needs to stay warm but get rid of the unnecessary moisture that could cause you to get and/or stay cold. Because of its lightweight properties, you won’t feel weighed down or uncomfortable. And it’s easy to stow away in case you don’t need it: the Core is compact enough to put under the seat of most bikes, or put away in a backpack. Take it everywhere you go, whether you’re on or off the bike.
