I purchased a pair of these for a 5-day hike into Panamint City, Panamint Range, Death Valley. They were nearly 2 pounds lighter than my old Vasques. I treated the leather with Snoseal and fabrix with spray silicone. Stayed dry through frequent dunks in the creek and the Vibrams were incredibly sticky on the bedrock slicks. I'm 200 lbs carrying 40 pound pack and was amazed at the traction. This is a killer desert boot.
