We created the Pyre Jacket for frigid sits, when your breath freezes in mid-air but retreating just isn’t an option. The 160-gram PrimaLoft® Silver fill is perfect when Jack Frost comes calling. Just to be safe, the Pyre is 100 percent waterproof, too — because cold and wet is a very bad combo. Finally, the Pyre’s articulated arms make it easy to adjust the hood, the cuffs, or get into your interior rangefinder pocket.
