Before any pair of Marbles is assembled, its frame components spend over 24 hours tumbling in a drum with wet stones ... smoothing away every edge the mold left behind. It is one of nine steps between raw material and the pair in your hands, and we filmed all of them in Mauritius with our production partner Plastinax.
"Price-to-quality is unreal, they’re genuinely the first pair of fishing glasses I’ve actually cared to protect. I also got hit by a massive streamer in the eye and I lived to tell the tale with both eyes intact and no scratch on the lenses ... super rad."
Fly Angler, Outdoor Filmmaker (Hook & Anvil)
“I used them a fair amount and they still look new. Super clear on the water, great for sight fishing. I found them pretty lightweight and no pressure on the nose or ears, which was nice.”
Guide & Competition Angler
“Super comfortable even after hours on the water. The curve of the arms made them feel snug without side pressure. I think are great for guides putting in long hours on the river.”
Artist, Fly Angler
“The lenses I field-tested exceeded my expectations - great visibility, full sun protection, and a wrap design that cuts glare better than pricier brands I’ve used. Very impressed.”
Fly Angler & Guide
“Really light frames, and overall solid on-water performance. Impressive for a new brand.”
Fly Angler and Hunter
“The construction feels rock solid. The frames hug your face, block glare from the sides, and stay in place even while moving. Very legit performance.”
Outdoor Adventurer and Wild Food Creator
“Already recommended them to other anglers. I love that the company recycles fly-line. The Zeiss lenses are top-notch in low light and the performance keeps surprising me.”
Angler, Guide, Show host
Our BEND frames were designed as a more technical offering that’s more forgiving for larger face shapes. The brow vent provides extra ventilation for humid environments and the wide arms and side shape allows for maximum coverage.
Pro tip: Order them. Try them. Return them if they don’t fit (for free)!
Every pair of BEND sunglasses comes packaged with intention. The custom tube, designed by artist Sarah Landström, pays homage to the fly rod cases we’ve carried for generations. It’s a functional keepsake — while also built easy to recycle if you already have a hard shell you love.
Inside, you’ll find a cream pouch made from rPET (recycled bottles), custom stickers and all the information you need to take care of your Marbles.
Yes. Both deliver the durability and performance you'd expect from premium fly-fishing eyewear. You may notice the recycled fish-net frames feel slightly less rigid than bio-based. That's the fishnets at work which in the core form are flexible nylon. That bit of flex means the frame is actually harder to snap, absorbing the knocks of a day on the water rather than fighting them.
Trick question, you don't need to. Marble lenses have been carefully crafted by Zeiss to ensure fogging is minimal. No one wants to fish in 360p.
Whenever you wear your Marbles we recommend putting the micro fiber pouch in a pocket. When transiting on long trips and expeditions, throw them in the provided tube and into your duffle or bag. Try to avoid leaving them in extremely hot conditions (ex: ovens, the sun, air-fryers etc.)
Does a brown trout eat a midge? Yes. You can use your Marbles on the ocean - just take extra care of the salt. We recommend our Dorado or Green Flash for ocean fishing. Whenever fishing salty environments, try to clean your shades after getting to land as prolonged exposure to salt may damage your frames and lenses.
If you smudge your lenses after inhaling a dozen chicken wings, use the included rPET cloth with mild soap and water. When on the river and in the wild, make sure to blow off any dust or debris prior to cleaning. Although our lenses are drop-tested, scratch tested and very durable, micro abrasions are still possible and most common when wiping your lenses with a piece of sand or small rock trapped. Treat your gear well. Don't lose your marbles.
