Yes. For this purpose we made  our special insert: you can choose between fleece and wool. Is that enough? Yes, even though it might seem strange, as we wouldn’t wear a thin softshell jacket when going out in freezing temperatures. That’s the advantage of wearing a suit, which ‘stores’ the heat :D. As the air doesn’t flow away – like from under a jacket – it creates something similar to an air-cushion. All the heat generated from your movement circulates inside the suit and around your body. 

Our insert can also be used on its own – for walks, chilly evenings at home, or for little babies worn in slings or carriers, as our suits are relatively thin and you can comfortably adjust the sling.
