care guide
the short version: rinse with fresh water, wipe with the microfiber pouch, and your glasses will outlast most things you own.
lenses
rinse first, always — water flushes away the dust and grit that scratch lenses when wiped dry. then dry and polish with the microfiber pouch your glasses came in; it's a storage case and cleaning cloth in one. skip t-shirts and paper towels, and keep them in the pouch when they're off your face.
frame
no rubber, no paint — nothing to get gummy or chip. the material is malleable, so you can adjust the temple tips to fit your head, tighter or looser, until they feel right. it's also highly resistant to chemicals, sunscreen, salt, and sweat: rinse with water and most things wipe right off.
hinges
after salt water especially — but also dirt, dust, or grime — rinse the hinges with fresh water. that's it. a quick rinse is the single best thing you can do to keep the hardware moving smoothly for a long life.
everything is serviceable
every component of your basn5 sunglasses can be replaced — lenses, temple tips, hinges, hardware. if you ever need a part or a repair, get in touch →. modest fees apply, but they're small next to new glasses and keep yours in use for years.
