The GL 01 is more than eyewear — it’s a frame born from a journey. Inspired by Daniel Dalen’s time in Japan, refined between Hong Kong and Amsterdam. Together with ETQ, he stripped back everything unnecessary until only the essence remained: a silhouette that feels right, every day, all day.
Behind a screen or out in the city — the lenses follow. Indoors, they stay light and transparent, so your eyes remain visible. Step outside and they shift into a deep grey, adapting to the light with subtle grace. Not a traditional pair of sunglasses, but a frame that offers the same UV400 protection when you need it. Blue light filters keep focus sharp, while the photochromic technology shields your eyes from sunlight with effortless transitions. A double-sided coating strengthens the surface, resisting scratches and enhancing clarity.
What makes this collaboration unique is the perspective behind it. Daniel builds with people, for people. ETQ builds with detail, for life. The result is a frame that does more than function: it reflects how you carry yourself, and how you are seen.
Available in Regular Fit and Wide Fit, the GL 01 is designed to belong to your routine. Made to feel effortless. Made to endure. Now, it’s yours.
Clear and protective. These lenses combine everyday comfort with advanced technology. Blue light blocking keeps your vision sharp during long hours behind the screen. Step outside, and the photochromic glass shifts from a light transparent grey to a deep grey tint, adapting smoothly to sunlight. With full UV400 protection, your eyes are shielded as if wearing a classic pair of sunglasses. A double-sided coating adds durability, resisting scratches while enhancing clarity. Built for daily wear, engineered to last.

How to measure
Let’s find your perfect fit. Place a sheet of paper on the floor against the wall and put your feet (with socks) on it, heels against the wall. Make sure you lean on your feet with full power when measuring. Now you simply draw a line at the end of the biggest foot. Measure the distance with a ruler and find the size that matches it: see size table. Are you in between sizes? In that case, we suggest taking the bigger size.
