For Everything except protection from brightness. Great for working, hunting or adventure dogs. Blocks UV is impact resistant and often is preferred by dogs. Great training lens, and when it gets scratched the scratches are not as visible to the dog as with other lens options.

Smoke

For everything! Overall the most versatile lens. Great for dogs that are rough on their equipment as it continues to offer good visibility when scratched.F

Blue Mirror

DM's are rolling in! The Blue Mirror lens adds a touch of flare and is one of our darker lenses for dogs who have sensitivity to light. Perfect for use in sunny areas and for those who love that blue mirror look.

Red Mirror

Giddy up! The Red Mirror lens is great for most dogs and is very similar to the smoke lens with a bit more style.
