Named after Mount Kebnekaise, Sweden's highest peak, Fjallraven's Keb Down Jacket for Men combines the most effective and industrious of outerwear technologies for an incredibly warm and impressive performance. Developed for thriving in varied terrain, this jacket knocks stereotypes out of the park with its hybrid qualities, rugged exterior, and unique bivouac-harness ventilation system. Built with both goose down and synthetic Supreme Microloft insulation, the Keb keeps you warm whatever the weather while the G-1000, weather resistant exterior and box wall construction offer unparalleled protection against the corrosive and bone-chilling elements often experienced in high alpine, trekking adventures. The jacket's bivouac harness permits optimal body temperature regulation without actually removing the coat itself, which is quite convenient when you're ascending through a scree field in gale force winds.
Im very satisfied with Fjallraven Keb Down Jacket - Men's Black/Black, L in general, and it works great. This insulated has best relation price-quality.
