Rex Specs were developed simply because our dogs needed eye protection. We ask a lot of our dogs - days on the trail, hours on the river, and peak upon peak. Both of our dogs were diagnosed with conditions made worse by extended exposure to the sun. After a failed search for a dog goggle that could handle our adventures, we created our own. Tested in the mountains of Jackson Hole, Wyoming, Rex Specs are proven to stay on through the biggest adventures to the laziest afternoons.
