Employing DownTek insulation that combines the all-weather reliability of synthetics and the lightweight compressibility of down the Big Agnes Men's Fire Tower Belay Jacket delivers maximum warmth for cold weather activities. A fully insulated hood extends coverage and enhances warmth.
The jacket is insulated with water-resistant 700-fill DownTek insulation. Renowned for their efficiency in retaining heat and compressible properties the feathers and fibers of down have an incredibly soft comfortable feel and despite advances in synthetic materials continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet but DownTek performs differently. Employing a unique innovative polymer application DownTek actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry longer and dries faster than untreated down jackets should it become wet. Perhaps most impressively DownTek retains 98% of its loft which translates into maintained warmth that untreated down jackets simply cannot achieve. Nylon ripstop shell fabric further protects the insulation while keeping weight to a minimum.
Further enhancing thermal efficiency the jacket utilizes Insotect Flow technology to help eliminate cold spots regulate the movement of down inside the baffles and offer better body heat distribution. Strategically placed Flow Gate construction eliminates lateral and vertical down shifting by using vertical chambers with "gates" to control the position and density of the down insulation.
Other features include a storm flap behind the two-way front zipper drawcord hem adjustability two zippered hand warmer pockets and two large interior mesh pockets. A separate stuff sack is included.
