Men's Sunglasses: Bio-Acetate Frames with Wood Temples
Every pair in this collection pairs a bio-acetate frame with handmade wood temples in zebrawood, rosewood, ebony or maple. Bio-acetate is made from cotton fibers and wood pulp rather than standard petroleum-based plastic, which is why the frames feel lighter and age differently than typical sunglasses. The Sumatra and Malibu are both round-frame models, with Sumatra offered in the widest range of colorways in the line and Malibu built as a lighter everyday option.
Built for Daily Wear
Every pair ships with TAC polarized lenses rated UV400, blocking 100% of UVA and UVB radiation, and CE certified. Stainless steel spring hinges adjust to different face widths, which is the main reason these frames stay comfortable through a full day of wear rather than pinching after a few hours. Whether the use case is a daily commute or a weekend outdoors, the lens and hinge specifications stay the same across every model in the range.
Choosing the Right Fit
Within the round-frame styles, size and coverage vary more than shape does. The size guide gives exact frame width measurements for each model, which is a more reliable way to judge fit than a product photo alone. All frames use stainless steel spring hinges, adding a small amount of flex at the temple that makes a borderline size more forgiving than a rigid hinge would be.
Frequently Asked Questions
What makes bio-acetate different from standard plastic frames?
Bio-acetate uses plant-based plasticizers made from cotton and wood pulp, instead of the petroleum-based plasticizers used in standard acetate and plastic frames. This reduces reliance on virgin fossil fuel and allows the material to break down faster than conventional plastic, though it is not a fully biodegradable material on its own.
Are polarized lenses actually better than standard tinted lenses?
Polarization filters out horizontally reflected light, which is what causes glare off water, wet pavement and car windshields. A standard tinted lens without polarization reduces overall brightness but does not filter that reflected glare, so two lenses of the same darkness can perform very differently in bright outdoor conditions.
What frame size should I choose?
Frame width is measured in millimeters and listed on each product page. Measuring your own face width at the temples and comparing it to that number is more reliable than judging fit from a photo. All frames in this collection use stainless steel spring hinges, which add a small amount of flex at the temple and make a borderline size more forgiving than a rigid hinge would be.
Do the wood temples hold up in hot weather?
Yes, with basic care. Wood handles normal daily heat well, but leaving frames in direct sun for extended periods, such as on a car dashboard, can dry out and warp the wood over time in the same way it would a wooden cutting board. Storing frames in a case when not in use avoids most of the wear that causes this.
What's included when I order a pair?
Every pair ships in a rigid eco case with a microfiber cleaning cloth, in packaging made from recycled materials. Each pair also carries a one year warranty.
Can I return sunglasses if the fit isn't right?
Yes. Full details on the return window and process are on the shipping and returns page, since sunglasses are one of the few accessories that are genuinely hard to judge from a photo alone.
