Wow. Wow. Wow.

"I really love these glasses. They feel solid and well-made, not flimsy like some frames I've had before. The quality is great, and they seem like they'll hold up for a long time. They also have a unique style that stands out without being over the top. I've gotten a few compliments on them already. Most importantly, they make me feel confident when I wear them—I feel handsome, cool, and like they fit my personality perfectly. Definitely one of my favorite pairs of glasses I've owned."

Best sunglasses for boat days

"I bought my husband a pair of sunglasses readers last year. We made a once in a lifetime trip to Spain and they still have sand in the frames. He loves it, but I thought he could use a fresh pair. These are exceptional, gorgeous color, exquisite fit. We are Caddis-forever-wearers!"

Love these!!!

"I wasn’t sure how these would look but I decided I loved the color and they look so good on most other people - plus the message on them is also cool… Turns out they are very cool! Comfortable… and the best ones I own- as are all of my other CADDIS readers. Unfortunately my husband always steals mine!!"
