Tested through 100 days of rain in the Northwest, with 700 inches of rain and snow, these pants made it through with excellent marks. Made to take you through any kind of weather with a combination of 2-layer Cordura fabric coated with DWR treatment to provide you with 20K mm waterproofing and 15K g/m2 breathability and fully taped seams, how could a single drop of winter get through the armory? Lined in Loft-Lite fleece for extra comfort, these pants are the strongest that Bonfire's got and are durable enough to take you all day and more without stopping.
