The Altocumulus Down Jacket by HIMALI™ is an ultra-lightweight, stuffable mid-to-outer layer designed for cold-weather activity in the mountains. It utilizes 850 fill-power ‘dry down’, a Pertex® Quantum ripstop nylon shell, and an eco-DWR coating to maximize it’s first level of defense against precipitation. The Slim, Athletic Fit reduces the volume and ‘dead space’, thereby increasing the performance. This insulation layer is toasty! It’s sure to be your go-to choice when temps drop.
