Wild weather swings are standard fare in South Dakota, where the temperature can rise or fall by 40+ degrees in mere minutes and lashing storms brew up faster than you can sprint for cover. It’s for just these changeable conditions that we created Black Hills Windfront Pants. The durable softshell fabric blocks wind when a front whips over the hills, sheds water when you're caught outside as the sky opens up. Better yet, the tough nylon fabric has a whopping 15% spandex built in for incredibly agile 4-way flex. And a hidden Crouch Gusset keeps the pressure off your privates when you step down from a tractor or clamber up a scree-covered slope. Get yourself a pair and work unfazed through whiplash weather.
