Unlike other materials, our soft 210T lining prevents and won't cause rubbing, sore spots, and fur damage. Instead, this soft lining will help keep your dog's fur coat looking shiny and healthy, while preventing hair damage, tangles, mats, and other common issues that can arise from friction and pressure on your dog's fur.
