Nothing beats the "Original." The Alaska Guide Creations Alaska Classic offers the classic design features of the original binocular harness chest pack Jaret developed 40+ years ago with today’s modern advancements in innovation and durability. As the mid-size line this pack is meant to accommodate full-size binoculars up to around 50mm objective lenses. For example, most 10×50 and 12×50 binoculars would fit perfect in the regular harnesses. H.B.S (Hook and Bungee System) closure allows for quiet, easy one hand operation to open and secure the main compartment.
