The Trapper Jacket combines features of several of Sun Mountain’s most popular styles. The shell is made with Zamza Light, a lightweight, proprietary Japanese fabric with 4-way stretch that is also extremely water-resistant and windproof. The insulation in this puff jacket is 37.5, a patented technology which works to maintain an ideal core temperature, enabling you to perform better, longer. Trapper is perfect for golfing on cooler, blustery days.
