Have you ever seen the letters “DWR” when talking about outdoor gear? DWR stands for durable water repellent. Montbell’s specially formulated DWR is called Polkatex, The one weakness of common water repellents is their susceptibility to friction and laundering. If you notice that rain is no longer beading off your jacket and instead soaking into the outer fabric, it means the water repellent coating has worn off. Unlike common water repellent treatments, we developed Polkatex to resist wear from friction and laundering, helping keep your technical garments performing their best.
