When it rains, it pours—especially in Montana, as those late-afternoon thundershowers hammer the hapless with raging wind and frigid raindrops. To fend off this fearsome weather, quality rainwear is essential. Enter Beyond, with its heavy-duty Arx 2.0 rain jacket and rain pant. The company's proprietary Lutra shell incorporates Cordura for a burly, wind-and-abrasion-resistant, fully waterproof fabric that can handle whatever's thrown at it, including exertion—multiple zippered ventilation ports allow body heat to escape, and side-zips on the pants offer quick donning and removal. This jacket-and-pant combo may not be lightweight or stuffable, but that's not what it's made for. It's designed to keep out water, which it does, meaning you can stay warm, dry, and comfortable, regardless of conditions. $298 for the jacket, $248 for the pants; beyondclothing.com.
