The Finntrail Thunder pants are lightweight waterproof shell pants designed for fishing and outdoor use in rainy and windy conditions. Their 2.5-layer fabric uses a TORAY Dermizax membrane rated to 20,000 mm waterproofing and 10,000 g/m²/24 h breathability. A DWR finish, fully taped seams and waterproof zippers improve weather protection. Waterproof YKK side zippers extend to knee level for easier on and off over footwear, while the ergonomic knee construction supports freedom of movement.
