  • Secure shades on hat: Highly recommended.

    I don’t wear hats often; I was unsure about these Underdogs.  Wow!  These polarized shades are great!  They make me want to wear hats more often.  I fish…a lot.  While wearing Underdogs they’re always where I left them…tucked away neatly on my hat.  I can wear them over my cheaters for tying knots, they stay clean, and the flip up/down action is smooth.  Great product!  I would definitely recommend them.

  • Always on my hat, no touching nose or ears.

    My husband and I love to play pickleball.  Great exercise and such a fun social game.  When not playing it is fun to chat with friends.  The bad part is that I have a tendency to leave my sunglasses on the “social” table when they should be on my face when playing in a match!  With the Underdogs  they are always on my hat and I love them.  In addition to always having them I love the fact that they don’t touch my nose and ears.

  • Flip, adapt, and conquer the greens with Underdogs!

    Today, my Underdogs were the perfect golf accessory. As the sun dipped behind dark clouds, a simple “flip” let me keep up with the changing light without the hassle of removing and storing regular sunglasses. They also make reading greens a breeze! I won’t golf without them!
