Purchased for a trip to the Amazon in 1999. Worn endlessly throughout every spring, summer and fall since.
Still in perfect condition .... And I am not easy on clothes.
Aside from wearing them in the Amazon jungle, the Australian rainforest, for months in Leningrad, more months in Zimbabwe, and Jamaica, as well as the US Southwest and all parts if Canada, the pure convenience of a secure inner pocket protecting your ID and valuables, they look great with minimal care as they prove with every day wear in Southern Ontario.
Thorny poisoned hooks, rabid insects of unknown names, even bites from a piranha are completely resisted.
After 22 years I would eagerly purchase another pair but why bother when this pair are in great condition and have truly become old friends .... They haven't aged ... but I, unfortunately, have.
