What Our Gearhead® Experts Are Saying:"This is the layer I throw in my pack no matter the mission. It’s warm for the weight, blocks wind better than a fleece, and disappears into my pack until I need it. From day hikes to ski touring, it’s always with me."From backcountry ski tours to breezy trailhead mornings, the Nano Puff Insulated Jacket is a versatile go-to for lightweight warmth. Built to perform when the temps drop and the wind picks up, this jacket combines sleek packability with insulation that works even when wet. It’s one of those pieces we always keep close, whether we’re headed deep into the mountains or gearing up for a chilly commute. The Nano Puff's 60g PrimaLoft® Gold Insulation Eco delivers reliable heat retention with low bulk, and its 100% recycled ripstop shell adds a touch of durability without extra weight. The DWR-treated face fabric helps shed light precipitation, while the brick quilt pattern not only looks sharp—it holds the insulation in place for even warmth throughout. Compressible, dependable, and built for movement, it layers easily under a shell or stands alone on milder days.
