Dark outside? Rainy weather? That doesn’t sound ideal. Let our newest pattern, Lumen light the way and make it all better! Lumen is just like our other classic patterns from our Waterproof AQUA Collection, however it’s the star of the show as it’s also Glow In The Dark! Not only is it easy to clean (the dirt and muck literally will just wash away), stink and rust resistant, but it makes your dog’s visibility even easier during nighttime walks or in limited light. Prior to use, please charge the product in bright light conditions. The intensity of the glow will gradually diminish. The brightness of the glow in the dark feature is subject to variation based on the charging light conditions. For your safety, this is not a substitute for proper lighting equipment such as a flashlight. To ensure maximum safety, it is crucial to remain cautious and aware of your surroundings during low light or dark conditions.
