What Our Gearhead(R) Experts Are Saying:"The Dawner Jacket is my favorite for high-intensity cold-weather activities. The Octa(TM) insulation is incredibly breathable, so I don't overheat, even during tough climbs, and it's soft enough to wear directly over a tee. I love how it packs into its own pocket-super convenient for stashing in my pack when conditions change."Designed for cold-weather adventures that keep our pulse up, the Stio Dawner Jacket combines warmth and breathability in one lightweight layer. The secret lies in its Octa(TM) insulation-a unique fabric that traps heat while allowing moisture to escape, ensuring we stay warm and dry even when the pace picks up. With a soft, grid-patterned interior that feels comfortable against the skin, this jacket layers easily over tees or base layers for flexible wear. The durable stretch outer moves with us, and a DWR finish protects against light precipitation, making the Dawner perfect for chilly trail runs, ski tours, and high-output pursuits. When temps rise, it packs into its own pocket for easy storage in a pack or vest.
