When chasing birds to the tops of peaks, flexible and unrestricted pants that still protect from the thickest of briars are a must. Cabela’s has answered that call with their Instinct Prairie Runner pants ($140) that are made with a flexible polyester/spandex shell and water-resistant nylon overlays to protect you in thick brush. I wore these pants on a three week road trip chasing birds across the west. Breathable and light, these pants allowed easy and quick movement while hunting running sharptails and huns across Montana.
