I just ordered my second pair of Dash XPs. Older version were lost, but lasted for 5 years before MIA. Native is great with fixing/replacing lenses and/or frames when glasses break - nose piece, lens, whatever, doesn't matter. Warranty service is sick. You just send in $25 with broken lens/frame and they'll send you a new pair.
Super light weight. I wear them for all outdoor stuff whether hiking, running, sailing, kayaking, etc. I sweat like a pig and glasses stay in place, no slippage, no fogging. Dropped them a ton, sat on them...and they still rock. Like them btter than Smiths, Nike and Oakleys
