These men's flip flops are lightweight yet-rugged and are tough enough for mountain life and comfortable enough for day-to-day wear and tear. The Men's Base Camp Flip Flop is a classic, rugged sandal inspired by TNF's hyper-durable expedition bags and designed with the same materials with extra cushy EVA egg-crate inspired footbed with anatomical arch support. The Base Camp Flip Flop has a Hypalon upper strap with soft PU binding and jersey lining to support all you coming and goings up hill and down dale.
