Great With Prescription Too!
I wear multi-prescription glasses and was hoping that these would work with my glasses; and they work perfectly together when extra sun protection is needed!

Flip Them Down When You Need Them, And Up When You Don't
Perfectly Crafted For Your Golf Game
Underdogs were inspired by the great game of golf, designed for players who sometimes want sunglasses during their swing and other times prefer a clear view. Our easy flip-up, flip-down action makes adjusting effortless. With high-grade polycarbonate lenses, they enhance contrast and visibility while providing shatterproof, impact-resistant protection against wind and debris. Unlike traditional sunglasses that press against your ears and slip mid-swing, Underdogs clip securely to your hat, staying in place. Say goodbye to discomfort and distractions—Underdogs move with you, keeping you locked in from tee to green.

Optimized Vision
Underdog Glasses feature high-grade polycarbonate lenses that enhance contrast and clarity, helping you track the ball against any backdrop—whether you're teeing off under bright sunlight or reading the green on an overcast day.
Effortless Flip-Up, Flip-Down
Golfers don’t always want sunglasses on during their swing. Our flip-up, flip-down design gives you full control, allowing you to adjust instantly to changing light conditions without removing your glasses.
No Slipping or Discomfort
Unlike traditional sunglasses that can slip, pinch, or create pressure points, Underdog Glasses clip securely to your hat, staying put through every drive, putt, and bunker shot. No more adjusting or dealing with distractions mid-game.
Polarized & Non-Polarized Options
Choose from polarized lenses to reduce glare off water hazards and bunkers or non-polarized lenses for better depth perception when reading greens—so you always have the right lens for the right shot.
