Here's what other sites are saying:
Rivers are often best in spring, but all that snowmelt can make for some damn chilly paddling if you're not kitted out correctly. Immersion Research's Arch Rival Men's Paddle Pant make sure you are, with a 3L waterproof and breathable WhiteOut membrane, fully taped seams, and waterproof neoprene gaskets to help you stay dry and warm when you're running icy rivers. The neoprene cuffs seal up tightly around your booties with a snug hook-and-loop closure, and the 3mm neoprene waistband offers a snug but comfortable watertight barrier around your midsection. The Arch Rival is made from seriously tough nylon, especially at the seat and knees, and has a zippered front pocket to hold whatever you need for a day on the river.
The Arch Rival Pant provides serious protection from the elements whether kayaking, canoeing or SUP (stand up paddling). Waterproof/breathable WhiteOut technology makes these great for when the temps make it too cool for shorts but a wetsuit may be too heavy. Super durable 400 denier nylon butt and knees keep these going for years.
