FANTAIL is rated 4.6949 out of 5 by 59.
Rated 4 out of 5 by from Best Sunglasses I've ever owned The only reason I didn't give this a 5 star is because the frames have stretched. The ear pieces fit perfectly for about 6 months, then they got loose. I got to the point that I had to wear my tether all the time so they wouldn't fall to the ground when I bend over. I am sending them in to have them fixed. With that being said, I would recommend getting the glass lenses. I have been rough on these and they don't scratch easy. I had polycorbonate before these and they scratched all over.

Rated 2 out of 5 by from Good shades...but The shades fit well and are comfortable to wear. Two bad things, with the glass lenses, they are extremely heavy and I have had to have them repaired twice in the past year due to the nose and earbar rubber becoming unlaminated from the frames. Never used to have this problem but have had had the same issue with the new Jose's also.

Rated 5 out of 5 by from Best glasses I've ever owned. I've had my fantail realtrees for about a year. I have a couple scratches but I know 100% that I am the reason for that. I work hard and they for my everyday needs From fishing to hunting to offshore to splitting wood to landscaping. They have been through also and stil stand perfect. A little fog from time to time but no big deal.

Rated 5 out of 5 by from Worth every penny. I bought a pair of mossy oak fantails w/pink 580p mirrored. I loved them I just hated that they cost me so much $277. I had never spent more than 10 bucks for sunglasses till I saw them. I had them about 9 months and we'll someone loved them more than me cause they were willing to steal them to have them. But now I can't afford another pair and IDK how I'm gonna to deal with cheap shades. They just ain't the same.
