Trangia 25 Windshield Upper Ul. This Camping Gear brought to you by Trangia is a lightweight and foldable windshield that keeps the heat in your camp stove burning even in the worst of weather conditions. The Trangia 25 Windscreen Upper/Downdraft increases the temperature of your meals by keeping the heat in your food warmer and cooking longer. The upper windshield has an enlarged air intake which keeps the flames burning for longer periods of time over the downdraft. The lower windshield has a broader mouth which admits more oxygen thus ensuring a consistent flame.
