Style Inspiration

Square running sunglasses with polarized UV400 lenses and featherweight, non-slip frames. The Sprinters' 50mm square silhouette is our best seller: sharp enough for the street, secure enough for the run.

Who square frames suit

Square frames add definition to round and oval faces, and the slightly larger lens gives more coverage against side glare than our round frames. They are a strong pick for men's running sunglasses and for anyone who wants more coverage on bright days.
