After 10+ years wearing the Smith District II sunglasses, I finally bought a new pair of shades. I loved my old ones, so this decision did not come lightly.
The Longfin Elite sunglasses are excellent. They offer broad coverage from top to bottom and side to side. The "fin" from their name refers to a side fin that offers side-blockage. They are polarized. This glare-reducing feature really helps them to reduce eye strain.
The nose and the ear pieces have rubber padding. This feature prevents the sunglasses from slipping much as a run for up to 3 hours at a time with them on or hike/climb for 12 hours. No matter how much I sweat and move, these glasses stay in place and stay comfortable. I really like them.
Since I spend so much time outside in rugged conditions, it matters that these sunglasses are durable. I have worn them daily for five months, and they still do not have a scratch or any signs of wear. I appreciate that they have resisted scratches.
These sunglasses are the right pair for anyone who spends a lot of time outside in rough conditions.
