Oakley HSTN SQ 2.0 Matte Grey Smoke / Prizm Ruby Polarized (OO9555-06)

Oakley HSTN SQ 2.0: the square one from the HSTN family, second generation

Square, with a straight brow bar and straight temples: the HSTN SQ 2.0 is the street version of Oakley's HSTN family, with an O-Matter front and chamfered corners. It is a size L frame with a 4 base curve, meaning a flat front: it sits naturally and covers without wrapping around your face. This unit comes in Matte Grey Smoke with Prizm Ruby Polarized lenses.

Signature details

• Square silhouette with chamfered corners: a square front with straight lines and cut edges, so it does not dig into your face.
• 4 base curve: a flat, non-wrapping front. It sits flat and covers you across the width without pinching at the sides.
• Large 54 x 44 mm lens: with a 21 mm bridge, it covers most faces without becoming a mask.
• Straight 142 mm temple: a thin, straight profile with the Oakley icon at the hinge; it does not catch when you take the glasses off.
• O-Matter frame: light and tough, built for everyday wear.
• Prizm lens with HDO: contrast and detail with Oakley's high definition optics.
• 100% UVA/UVB/UVC protection: included, one less thing to think about.

Prizm Ruby Polarized lenses

Ruby mirrored with a polarized filter: the mirror gives it character and the polarization kills glare from water, road and snow. Inside, it lifts contrast on greens and browns without making everything dark, so it works in the hills and in town.

Can it be glazed? Yes — and this HSTN SQ 2.0 is built for it.

The HSTN SQ 2.0 takes Oakley's Rx service: it can be fitted with original factory prescription lenses (Oakley True Digital) with no loss of Prizm technology or UV protection. We fit them in our own workshop, with registered optometrists and a 2-year European warranty.

Frequently asked questions

Is it an original product? Yes, 100% factory original Oakley with its identifying model code and a 2-year European warranty. Centro Óptico Alpedrete is an authorised official retailer.

What size is it? Size L: a 54 x 44 mm lens and a 21 mm bridge. It covers most faces, but with a 4 base curve it sits flat instead of wrapping. If unsure, send us a WhatsApp with the glasses you wear now and we will tell you whether this pair fits.

Who is it for? For anyone who wants a square street frame with character —straight lines, straight temples— rather than a sporty one. And for anyone who wants to have it glazed without giving up Oakley's original lens.

Can it be glazed? Yes. Oakley offers a prescription service on this frame and we fit your prescription with original Oakley True Digital lenses: message us with reference OO9555-06 and we will confirm the best option.

What case is included? Oakley does not supply a case with these glasses. At Centro Óptico Alpedrete we are committed to protecting your glasses, so we give you a simple but very practical zipper case. And on top of that, our famous premium digital microfibre cloth.

What does Prizm mean? It is Oakley's lens technology: it tunes contrast and colour so you see more detail. Each Prizm lens is refined for a specific use.
