I left a full flask of ice cold water in it over 36 hours and was shocked that it was still ice cold when I actually sucked it up the straw.This was an amazing find now although I’ve never tried it with hot liquids I have no doubt that this would keep any liquid. I have hot all day no trouble at all.The seal must be absolutely superb for it to have kept my drink cold for so long when it comes to functionality I find it suits my needs as my hands are not very strong. I like the fact it has a strap handle so I can hook it out to bring it to me. I like the fact that I do not have to push very hard on the hinge of the straw for it to come up and although at the beginning I couldn’t unscrew the cap that was not because it wasn’t easy to undo, but because my hands are not strong enough. With such a wonderful choice of colours I chose pink because it matched my cupholder which it fits very very well.Although some people might think the price is quite high, I think considering this has kept everything colder than I ever expected longer than I ever expected. It is definitely worth every penny I spent and I’m considering buying a second one.If I could give it 10 stars I would that’s how good this is-if you haven’t bought one yet I can definitely recommend you do. ### ⭐⭐⭐⭐⭐ Great product, built to last *by on Reviewed in the United Kingdom 8 July 2026* Really well built and should last years, looks great also, keeps things really cold especially in this heat ### ⭐⭐⭐⭐⭐ Great bottle *by on Reviewed in the United Kingdom 10 September 2026* Light weight no leaks and keeps drinks cool for hours --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/683154161-hydro-flask-standard-flex-straw-cap-621-ml-21-oz](https://www.desertcart.hr/products/683154161-hydro-flask-standard-flex-straw-cap-621-ml-21-oz) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-30*
