The biggest issue with these are they are not for very active wear scenarios...they are loose and can easily fall off your head..OK for driving, even biking but forget skiing etc.

Native makes a bomber pair of shades! I stomped right on my pair with my hiking boots, should have destroyed these but the lenses popped out and were a little cracked in the corner but are still totally usable. Any other pair of sunglasses would have been toast. Aside from being bomb proof these are very light and great for running and hiking, and the low-light polarized lenses great for fishing. I wear these every day!

First of all...these are a LARGE profile per Native's website not Medium as noted in the 'Tech Specs' on Backcountry. I've been wearing these for 6+ months and I'd say more like L-XL but idk. These replaced my Native Sprint's w/ blue reflex lenses that I had for years but lost on a hike. The Ultra XP's are top quality as expected from Native but they are a little wider than my old pair (as previously noted) so they don't hold in place as well. Also, both had the same blue reflex lenses but I feel the Ultra XP's are only half as dark as my Sprint's were. My eyes are sensitive to light so this was disappointing but I still love them, will not leave home without them and will continue to purchase Native Eyewear.
