I’m am completely sold on this product. I purchased one and loved it so much that I bought another for a good friend of mine and am about to purchase one for my hubby. I live and run in Singapore and it is hot and humid here EVERY.SINGLE.DAY of the year. Before our Circuit Breaker (COVID shutdown) began, I usually depended on the water fountains around the Marina Bay Area. Those were turned off about 2 weeks into the shutdown, so I needed something else. I was using a handheld Nathan bottle that is okay, but it only holds 17oz and the strap really irritates my knuckles. Plus, it gets warm very quickly - even if I start with a frozen bottle. I ordered the HydraQuiver and have so far used it for two half marathon distances and several shorter efforts. No chafing, no bouncing or moving around, ample storage, the bottle is easily accessible and stays cold. The night before my morning run, I fill with hydration, and place in freezer without the lid. In the morning, I take it out, put on the lid and the liquid easily stays cold for over an hour and even longer if I’m not in direct sun. I am so thankful to have found this product - best hydration setup I have ever used!!
