Cycling sunglasses

We’re sorry, this product has already done its all on the field and has retired in style.
It was an MVP in its prime, but both in life and in sports, there comes a time when even the greatest must hang up their boots and pass the baton.
Thank you for being part of our history!
As we say goodbye, the game continues. We have a team of incredible products in our store and new additions for this season that promise to be spectacular. Don't miss out!

All mirrored styles belonging to the K3s collection count on REVO coating as well as on our DrySky ventilation system to guarantee excellent vision in any situation.

This product includes PU hardshell case, microfiber pouch and replacement rubber bands for temples and nose pad.

Available K3s accessories: photochromic lens, TR90 optical clip, anti-fog lens and clear lens.

  • Please avoid contact with makeup, creams, or similar substances when trying on, as these can cause stains, especially on light-colored products.

  • Protect the lenses properly by using the case and pouch included with the glasses/goggles.
