An everyday waterproof jacket, with a removable warm fleece inside. Wear them separately, or both together if it's really cold and wet.
The Berghaus Calisto 3 in 1 is a versatile jacket/fleece combination that you'll find useful all year round.
The outer jacket is an interactive, lightweight waterproof and breathable jacket with a casual, comfortable fit, made from Berghaus’ own AQ™2 fabric.
The removable inner fleece will give you the winter insulation you need out on the hills. It works well on its own as a light layer of warmth, perfect for cool summer evenings - but secure it inside the outer (using the InterActive zip and attachment points) and you've got a warm, waterproof and breathable shield from the worst of weather.
