Rainbow Trout

Alright gang. We got up before dawn. We packed the cooler with sandwiches. We scoped out the river current, kept an eye on drifting foam, and noted a particularly promising rock garden to aim at. All that’s left is to nail that perfect cast and bring in the trophy trout we came for. Although if we’re being honest, it’s not just about the number of fish we catch and release, right? Even if a bite never comes, any day on the water is good for the soul.

If a couple hours of casting is your idea of time well spent, reel in a pair of the new Rainbow Trout Fast Lanes before the run is over!

Reel them in!

The Rainbow Trout Fast Lanes Sport encapsulate the simple beauty of their eponymous fish. Blue-green at the top of the speckled frame fades gently to crimson before ending in translucent beige, mimicking the iconic coloration of the Oncorhynchus mykiss. This pattern continues down each arm, while polarized deep water green lenses (complete with a fish hook lens etch) and silver hardware round out this pair for a look that comes straight from the streams of Montana.

Designed on one of our most popular frame styles, the Fast Lanes feature clean-cut, rectangular lenses, and provide full UV400 sun protection. Every pair comes with a microfiber babbling river protective pouch and a numbered edition card.
