I bought 2 different products that lasted for several years as main bottom wear for whitewater rafting as a professional guide. Comfortable and durable. Great to have the belt loops. The products I had previously had incorporated belt so no need for the loops n those. I have tried mtn biker guy shorts with only velcro for adjusting and it doesn’t cut it for when swimming trough rapids or even when they’re wet and walking around. I will be buying the Hummvee II, 3/4 for whitewater sports and come back to give a review about it
