TR-90 is a special Swiss-made thermoplastic. That may sound technical — but here’s what it means for you:
It’s super light, crazy flexible, and built to last.
From Delhi’s dry heat to Kerala’s monsoons and Himachal’s icy wind — TR-90 frames don’t crack, melt, or lose shape. They just… work.
TR-90 frames are way lighter than regular plastic or metal. That means:
No pressure on your nose during long runs
No headache after hours of cycling
No bounce or slip during treks
💬 “I wore them for a 15K run — forgot I was even wearing shades.” – Kabir, Trail Runner, Hyderabad
TR-90 doesn’t snap like cheap plastic. It flexes and comes right back.
Dropped them? No crack.
Sat on them? Still good.
Threw them in your gym bag? No stress.
That’s why many call these “unbreakable sunglasses.”
TR-90 doesn’t absorb sweat, won’t get sticky, and doesn’t warp in heat or cold.
Unlike basic plastic frames that:
Get brittle in winter
Melt shape in heat
Feel sticky in humidity
TR-90 stays rock solid.
