Ok, I'll be honest I've got a big head and many sunglasses (all of them) make me look cross-eyed when I put them on! The width of these are great and the cut of the lenses a lot more than the Hardtops. I do agree with STW that they let a bit too much light in from the top. Also I wish Native added all polarized lenses with the Dash SS. Only the main lens is the polarized (already installed in the frame), so you could switch them out but your not getting the same performance. I hate to be so critical because I really love these shades and honestly those two things are very minor!! So if you've got a big head like me, fear not! You've found your shades!

I've had these sunglasses for about a year and they are great performers. I bought primarily for running, which they excel at. No budging or slipping when I sweat and I forget they are there. Venting at the top is adequate as well, although I have experienced days where they fog up under high humidity conditions (i.e. trail running through a cloud). Lenses are a breeze to snap in and out, although I only really use the polarized and the yellow lenses. Usually will swap in the yellows on rainy days to keep the rain out of my eyes.

Apart from running these are my everyday sunglasses. Biking, driving, you name it they go with me everywhere. Good durability, no scratches to speak of. If anything ever does happen to them I will likely replace them with Native's outstanding warranty program. No reason to switch.

Should mention that the case that I got with mine is not the one pictured in the Detail Views. It's a pretty low end soft case, but I actually prefer that as it does not take up as much room as a harder case would.

Great glasses again by native. This is me 3rd pair of natives I keep one pair in each of my cars and a 3rd pair for when I have to send them in for exchanges. Was disappointed that native stopped having 4 sets on lenses, but the new sport flexes are good. Hope this helps somebody.

Super glasses. These are extremely light but have the durability I was looking for. There is no sliding due to sweat or rain and at the top of a lense there is almost a "ceiling" on the glasses to keep out sun. There is no problem with the ear pieces coming loose. Lenses are easily changed but don't snap out when you don't want them to. I wear a 7 3/8 to a 7 1/2 size ball cap and these fit wonderfully. I found mine on sale and with two extra pair of lenses. Well worth the money.

I love this style of sunglasses - with replaceable lenses and no frame on the lower section. And these Dash SS are extremely nice glasses. Excellent optical quality. Extremely comfortable. Very light weight. A few minor quibbles: vertically speaking, these glasses offer very little coverage. From top to bottom, they are very narrow. On my face, light comes in from the top and bottom. Horizontally, they are fine. Second complaint: they come with 4 lens options: Brown (polarized), Orange, Yellow, Clear. Brown is good all purpose, but not dark enough for really bright conditions. Orange and Yellow are too close to each other to really be helpful. Clear are pretty useless for me. I'd rather have had a really dark lens for snow, on-water in the tropics, etc; a normal brown for normal sunny conditions; and yellow for fog/low light.
