The best self-sanitizing water bottles that are perfect for golfers

A reusable water bottle is a necessity for golfers. It’s a great way to stay hydrated and go easy on the environment by avoiding single-use plastic bottles. As with most products these days, you can take your water-bottle selection to the next level with “smart” bottles containing futuristic technology to keep your water cold, tasting great and even eliminate harmful bacteria. Self-cleaning water bottles make it safer to drink from the tap or on-course water coolers. Most of the bottles below filter out 99.9 percent of toxins, but common sense prevails in that you still should never drink from a pond or standing water you come across.
