The warmest insulation layers Jones makes are made with 100% recycled 750-fill down for the perfect ultralight mid-layer in the winter and a packable jacket in the shoulder seasons. The Pertex face fabric provides high performance with a DWR water resistance, and a new baffle system gives you more warmth on cold days in the mountains in an even lighter layering piece. To save space in the pack this tucks into its zippered internal chest pocket for a jacket that’s in Jeremy Jones’ back, or in his pack, every time he leaves the trailhead. A down midlayer is an essential for backcountry riding, cold weather camping, and lift service on a bitter day… that arsenal core piece that’s with you whenever you’re headed out to explore in the snow. Whether you’re slipping into it on a windy summit or layering it under your shell so you can slay it on the lifts the Re-Up is down for the cold.
