Review: A little tough to disassemble but great otherwise - A little tough to disassemble but great otherwise. The nozzle is very difficult to take apart for cleaning. Otherwise I love these things. Review: This is my everyday/everywhere water bottle - This is a great little water bottle. I really like the feel of the silicone, I use it nearly everyday and it is holding up fine. As much as I love it, there are three things to be aware of before buying it: #1: It is small. It is hard to tell from the pictures, and even in person it looks like it would hold more water than it does. This is both a good and bad thing, it makes it light and easy to travel with, but not a lot of water. I think it is about half the size of a standard plastic bottle. On the plus side, this means it easily fits in a bag or purse. It is actually small enough I could carry it in the side pockets of my leggings. Not sure how comfortable that would be, but it fits. #2: It does not stand up on its own. This is very clear from looking at the design of it (it does not have a flat bottom) but somehow I did not expect that. This is not a problem if you plan to take it in a bag, but I would not take it out with me and set it on a random table because it can be hard to keep the nozzle off the ground. #3: To drink water out of it, you use your teeth and put pressure on the top and bottom of the silicone part of the nozzle. (This was the weirdest one for me.) This breaks the seal and lets the water out. It was strange at first, but I really like that aspect now. I makes it almost impossible for the bottle to leak, at least through the nozzle. And you don't have to worry about any kind of cap. It also makes it easy to use with just one free hand. I was worried this would wear out, but I empty and refill this bottle multiple times every day, I have had it for months now, and it is shows no signs of wearing out. As long as you are okay with a little water bottle, I really recommend this one. I would not take this on a multi hour long hike, but when I go out for a walk, or run to the store, this one comes with me :) ## Features - HANDHELD RUNNING WATER BOTTLE- Our compact water bottle makes an ideal running hydration bottle.

I use this for hiking and trail running, and also to bring into concerts for water, on flights, and I also leave it in my car to grab a sip while driving. Super convenient. Bite valve works perfectly. No leaks in the water compartment. Would buy again! ## Frequently Bought Together - Running Water Bottle Hand Held- 8.5oz Flexible Running Bottle | Collapses As You Drink, BPA/PVC Free Soft Water Bottles for Hydration Pack/Running Vest for Jogging, Running, Hiking & Travel (Two Pack) - Honey Stinger Energy Gel Variety Pack | 5 Packs Each of Gold and Organic Fruit Smoothie | Gluten Free & Caffeine Free | For All Exercises | Sports Nutrition for Home & Gym, Pre and Mid Workout - UTOBEST Running Vest, 5L Hydration Vest Lightweight, Breathable and Sweatproof Running Backpack, Adjustable Running Hydration Vest for Trail Running Marathon Race Jogging Cycling --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/676625032-running-water-bottle-handheld-flexible-water-bottle-8-5-oz](https://www.desertcart.hr/products/676625032-running-water-bottle-handheld-flexible-water-bottle-8-5-oz) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-25*
