Providing warmth, breathability, and fast wicking performance, the Graviton Jacket is a versatile mountain midlayer. With excellent stretch and set-in sleeves for complete mobility and a slim fit, it’s ideal for layering on mountain ascents where climbing, ropes or a harness may be needed. For added comfort and wind protection the Graviton has a double layer, stand-up collar with a zip guard and roll-over fabric for snug, soft protection around the neck and chin. The dropped hem at the back neatly covers over the back of the hips for a seamless fit under a harness. Packable, warm and temperature regulating, the Graviton Jacket is ideal for all mountain adventures.
