A few months ago I lost my sunglasses (which were Native Dash XPs) and ordered these Hardtops as a replacement, and really wish that I had upgraded sooner.

My head is a bit on the larger side, and these sunglasses fit it perfectly.  They look cool, and are very light.  I wear them hiking and cycling often, it's very comforting that I never feel like they're about to fly off of my face.  The lenses wrap around my eyes and sit almost snug against my cheek, so no light comes in through the sides - which is a major improvement over my DashXPs, which weren't as effective as I would have likes when it was very bright out.  Highly recommended, and if I lose these (like the last ones) then I'll definitely be buying another pair!
