HSTN SQ Sunglasses

Whether you're glassing a tree line at dawn or running a ridge in August, the HSTN SQ is our go-to pair for hunters, hikers, and runners. Prizm lenses sharpen contrast so ground changes and terrain stand out in harsh Southern sun, while the lightweight O Matter frame stays put when you sweat.

• Prizm lens tech tunes color and contrast so roots, rocks, ground changes, and tree lines pop in bright Southern sun
• O Matter frame is lightweight, flexible, and tough enough for the truck console, pack pocket, or a rough trail
• Squared-off shape gives more coverage than a round frame and fits a wide range of face shapes
• Plutonite lenses block 100% of UVA, UVB, and UVC for full-day protection in the field, on the water, or on the road
• Four colorways: Prizm Ruby, Prizm Grey, Prizm Tungsten, and Prizm 24K Polarized to cut glare off water and wet pavement
