Medium-Large Fit: 178mm arm length, 135mm across the front
Hydrophilic, adjustable nose pads and temple tips
TR90 and stainless steel come together in this RX-ready model to form a frame that looks like it belongs no matter where you wear it. Whether you're sporting a bike helmet, a designer suit or a bathrobe that's a little too small, the Boundary is the frame that always makes sense. This is partially due to its adjustable parts and hydrophilic pads that become more grippy when wet.
