A classic insulation garment for all your outdoor adventures. The THUNDER BAY is our all-time classic fleece jacket with a zip-in option. It is equipped with our REGULAR system zip so it can easily be docked with a compatible TEXAPORE weatherproof jacket, to act as an insulating liner. Worn on its own, it also forms a cosy barrier to the cold. The 200 velour fleece we have used here is very robust, so chafing from pack straps is not an issue. And it wicks moisture to the outside just as fast as it absorbs it. These are key functional attributes when you are planning lengthy walks in cold weather.
