It Holds Water. *by P***O on March 6, 2025* The water bottle works great. It keeps water chilled rather well.If you're in it to save some plastic, great! It'll last you a long time. If this is your 5th one, I think it defeats the purpose of being "green." But that's a different conversation.How cold does it stay? Long enough. If you want it to stay cold 12-24 hours, that also defeats the purpose. Drink your water. Why do you need your water to be cold tomorrow? Drink your water today.What I love about this compared to other bottles I've used before or seen:* Wide Mouth - easy to add ice. Easy to drink out of. Easy to clean.* No Straw - no concern about getting Smoker's Lines.* Size - some other bottles of the same external size are about 32 oz vs. 40 oz.* Handle - Fun to swing.* Doesn't Spill. ### ⭐⭐⭐⭐⭐ So easy to carry and no wrinkles around my mouth from a straw *by C***E on May 9, 2025* This is my third Hydro Flask! I love these drink cups. I do have to buy the rubber bottom for them since they do dent if you drop them, other than that they hold up very well. The mouth has a wide top so it is easy to fill with ice. I enjoy that is does not have a straw to drink from. Not a fan of the straws since they are harder to clean and they cause wrinkles around your mouth. My drinks stay cold, I even have ice in my cup by the next morning if I have by my bed. I have never had one leak so that is not a problem. Many colors offered also. ### ⭐⭐⭐⭐⭐ ~ Hydroflask Fan Since 2017 ~ *by S***N on May 23, 2025* Let me preface this by saying I've been a hardcore hydroflask fan for a while now. I was in need of a new water bottle and saw that this was on sale, so it was a perfect purchase! This hydroflask has held up nicely, and I love how I can shove it in my backpack and go, especially without it leaking. Super easy to clean with a bottle brush too! This has helped me drink more water, especially because I enjoy it ice cold, and this thing keeps it cold for a long time! I also want to add that this size is PERFECT. Not too big, but not too small either.Hopefully this review helped you in your decision and thanks for taking the time to read! :) ## Frequently Bought Together - 20 Oz Wide Mouth Flex Cap Moonshadow - Hydro Flask - Flex Cap for Wide Mouth - Leakproof - Honeycomb Insulated Cap with Flex Strap for Easy Carrying - Black - hydro flask - flex for --- ## 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.co.uk/products/681915265-20-oz-wide-mouth-flex-cap-moonshadow](https://www.desertcart.co.uk/products/681915265-20-oz-wide-mouth-flex-cap-moonshadow) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-03*
