The Kelvin Down Ultralight Jacket is single minded in its intent: ultralight, packable and warm. This minimalist mid-layer wraps your upper body in 3.2 ounces of 750 fill-power PrimaLoft® Gold Down Blend insulation, delivering highly efficient insulation even when wet.
Pockets protect your hands while a zippered chest pocket secures your necessities, and doubles as a stuff sack. In fact, the chest zipper is built with an internal pull, so you can turn the pocket inside out, stuff the jacket into it, and easily zip it closed. Designed to be worn under ultralight outer layers, like the Dewpoint or Jetstream Lite jackets, the Kelvin Down Ultralight Jacket is the cornerstone of your light and fast backpacking system.
