I started using the old-style Water-to-Go bottle a few years back. The photo of the old-style bottle is in Nepal and the other is here in Wales. I have been using my Water-to-Go bottle for all of my travel and hiking adventures over the last four years. They kept me safely hydrated on hiking trips around the Himalayas of Pakistan and Nepal where I could fill with confidence from rivers and streams. During a three-month tour of India, I used my Water-to-Go bottle at every stop and didn’t get sick once. This year I used my bottle with confidence on a camper van tour from the UK to Georgia and closer to home I always use my bottle whilst hiking the mountains of Wales. It hasn’t failed me once!
