These Doggles are red with attitude... New patented interchangeable lens system for dogs. -Our new and improved frame has been completely redesigned. Doggles ILS offers a deeper lens cup, very flexible frame, and wider nose bridge. ILS were designed from the beginning to be lighter and more comfortable for dogs. After eight years of designing eyewear for dogs, Doggles ILS has arrived. As with all Doggles, goggles for dogs, you still get the 100% UV protection, shatterproof, anti-fog lenses which Doggles are known for!
