Meet the ACG Lava Series

ACG Lava jackets are molten warmth for biting cold. With insulation-filled baffles inspired by the billowing, wavy appearance of pahoehoe lava flows, each Lava jacket is made to warm your torso in a different type of situation.

Get this one for long hikes or backpacking trips in the frigid outdoors. The Lava Flow Ultralight is exactly what it sounds like: super light and packable with an exceptional warmth-to-weight ratio courtesy of quick-drying ExpeDRY™ down. It's built to work well on its own or as your mid layer.

Get this one if you need a trusty, warm jacket you can reach for all winter long. It's full of PrimaLoft® synthetic insulation that retains its warming properties even when wet. Plus, it's got a slightly looser cut with lots of adjustability.
