Nothing beats the warmth-to-weight ratio of down insulation. We designed the men''s Burton Mid-Heat Hooded Down Insulated Jacket for easy layering under your shell, so you can stay warmer and ride longer. We added just enough high-loft down to turn up the heat without creating too much bulk. Lightweight ripstop fabric keeps it durable without limiting movement, and it resists light weather, so you can wear it on its own, too.
