Review on 21 oz. Stainless Steel Hydro Flask Standard Mouth Water Bottle with Sport Cap - Reusable, Vacuum Insulated by Christopher Buck

I rarely give 5 star reviews but this case is perfect for my needs. I mainly use it for short bike rides as I live in Florida and needed a product that would keep water/ice cold during my daily bike rides. Trust me this is perfect for keeping liquids very cold for long periods of time. I will add that I'm not the one measuring if it lasts for days as I didn't buy the product for that. In addition, the hydroflask fits perfectly into the Topeak Cage 2 for my purposes and can be rated well. The spout is perfect as I had no problem drinking while driving. Some have reported leaks but I haven't seen any so far but note that the website says this product is not waterproof as there is a tiny hole in the sports cap that liquid can leak through when drinking. I'll also add that the hole is big enough for medium ice cubes, so again it serves my purposes. Finally the quality is second to none as I've been using it for over a month now and the paint quality hasn't diminished. Another great product; it is as advertised. Hope that helps!
