POSITIVES: these glasses are very comfortable to wear. They are well padded on the nose area & not only does the lens wrap around the eye but the legs which fit over the ears, seem to hug the glasses onto your face, this is such a help when jogging or mountain biking over bumpy ground. They also look really cool & I just love the colours which look great with my pink running stuff. Because the legs are slim, the do not interfere with a baseball type hat, as some of my other sunglasses do, where the hat pushes the glasses down hard onto my nose, not so with these glasses, very comfortable. I have not found the different rainbow colours show up or interfere with my vision when looking out through the glasses.
NEGATIVES: the glasses arrived in only a padded A3 envelope, surely a recipe for disaster when travelling through our postal system? When I took them out of the envelope one lens fell out (I read this happened to another reviewer too). It took me some time to get the lens to fit back in, but I succeeded, I assume the package had been squashed to cause this. The glasses take up a fair bit of room with the legs closed because of the curvature of their shape, so if carrying space is short you could have a problem, I'm thinking here of a little bum bag/hydration belt type bag as used by runners. They come with a flimsy fabric case, not really a case but a stitched bit of material, a hard case would be better, but at this price I do not expect to get this. For the price you cannot really go wrong with these, but I think I would not have bought them for the full quoted retail price.
