Review on 🏃 Nathan SpeedDraw Insulated 18 oz Handheld Flask for Running and Hiking - Replacement Water Bottle by Brockington Zuniga

I already own several non-insulated SpeedDraws and have been using them for at least a few years. My problem in the Florida summer is that the drink in it heats up too quickly. I usually load it with ice, add the solution, and then top up with water. So that's pretty much all ice cream for starters. After 45 minutes the ice is completely gone. The warmth of my hand accelerates the heating. At 1.5+ runs it will be a warm liquid. After researching and reading all the reviews for the vacuum flask version, it sounded promising. It says it can stay cool twice as long. In this case I should expect the ice to last more than 45 minutes and still be cool for 1.5 hours. I have insulated water bottles so I know how they work. I will say that this is just an ordinary bottle.1. It's well made but doesn't feel heavier than you'd expect from an insulated or non-insulated water bottle, for example. 2. It's more flexible than Nathan's standard bottle. This can be a problem for those who forget to depress the plunger after drinking as you are likely to accidentally release the liquid.3. The fact that things stay colder than a standard bottle is not at all noticeable. To be honest, I just can't say how long the liquid stays cold between the standard bottle and the vacuum bottle. This is a bigger issue for me because I bought this to replace the stock bottle I have with something I thought would be at least a little bit better. won't get you anything I'd noticeably say. If you don't already have Nathan Quick Draw, paying more for isolation isn't worth the extra money. Another side issue is that there can be leakage between the two layers as seen in some people's reviews, unlike the standard bottle which doesn't have two separate layers.
