What Our Gearhead(R) Experts Are Saying: "I like these when I want something understated but still distinctive. The squared-off shape feels more structured than the original HSTN, and the O-Matter frame keeps them light for all-day wear. The Unobtainium nosepads are clutch-they stay put even when it's warm out, and the Prizm lenses make everyday light feel crisper." Subtle doesn't have to mean boring, and the HSTN SQ Prizm Sunglasses prove it. Oakley refines the original HSTN attitude with a squared-off silhouette and modular color play that feels modern without trying too hard. Clean lines and premium metal details elevate the look, making these sunglasses an easy choice for everyday style with a little extra edge. We reach for the HSTN SQ when we want comfort, clarity, and confidence built into one frame. The O-Matter construction keeps things lightweight and resilient, resisting warping through daily wear, while Unobtainium nosepads increase grip as things heat up. Paired with Prizm lens technology that enhances color and contrast, these sunglasses deliver a polished balance of lifestyle appeal and Oakley performance for wherever the day leads.
