N/S18
Standing for 18% Nickel-Silver, N/S18 is the lightweight, durable and extremely corrosion-resistant alloy we use for all of our metal frames. A combination of nickel, zinc and copper, N/S18 gets its high strength from the high concentration of nickel. As a precaution for those who may be sensitive to some metals, we apply a hypoallergenic polymer coating to all of our metal frames.

DURABLE
N/S18 metal is extremely durable due to the combination of its flexibility and high strength.

LIGHTWEIGHT
Weight is an important factor when choosing a comfortable pair of sunglasses. This is why we use lightweight N/S18 and pay close attention to weight when designing all of our metal frames.

HYDROPHILIC ANTI-SLIP FEATURES
All of our N/S18 sunglasses have hydrophilic [anti-slip] nose pads and temple tips. This material is so effective that it actually grips better when it’s wet — exactly when it’s needed.

ADJUSTABLE NOSE PADS
Adjustable nose pads are available on all of our N/S18 frames. A great feature for customizing the fit of your glasses, these are especially beneficial for hard-to-fit faces and those who need to adjust the fit to accommodate long eyelashes.
