Whether you're getting gear lined out at the crag or digging a snow profile pit by headlamp, the Black Diamond Men's Hot Forge Jacket will keep you warm without adding unnecessary weight or bulk to your backpack. Weighing in at 13 ounces, the Hot Forge offers maximum warmth and durability in a lightweight design that isn't going to easily tear on you. Stuffed with PrimaLoft Gold insulation, it uses a blend of weather treated goose down and synthetic Primaloft fibers for maximum compression that will maintain insulating properties even after getting wet. DWR treated on the inside and out, the lining and shell material will resist moisture from sweat and light rains and snow. A zippered chest pocket lets you keep you notepad for your pit profile handy, and two internal drop in storage pockets accommodate climbing skins or climbing gear. A close to body fit makes it great for layering under a shell without feeling like a double puffed marshmallow.
