Its some what flexable but its big and almost didnt fit inside the pouch on my back pack...there was no condensation from bag thru back pack and extended the cool water time..my other pack didnt have the insulating sleeve and ice cold water was warm within about 2 hours..this 1 stayed cool the entire day of use..i filled half way with ice and topped off with water. I would reorder if i some how mess this 1 up ### ⭐⭐⭐⭐⭐ Good design and quality. *by T***H on Reviewed in the United States on September 1, 2020* PROS:*Thicker then original bladder that came with fly backpack.*Black bladder and dark tube. Prevents bacterial to grow and keeps water cooler keeping it dark.*Very good open seal from the top. Slide/lock mechanism. Can be kinda hard to open or close, but you are sure its closed when it is.*Tube quick disconnect*Disconnected tube will not let water come out of the bladder because there is a valve that stays closed unless tube is inserted. This is the best feature yet.*Because of the valve in the bladder inside quick release tube connector, you dont have to pull the tube out with it for a refill or maintenance.CONS:None. ### ⭐⭐⭐ Great concept with a fair design for the price. *by J***. on Reviewed in the United States on September 2, 2021* Comes with a cleaning kit and a outer insulation pouch that will keep your fluids cool and keep the bag protected from possible punctures. The bladder is made with a thin and flimsy plastic. Wasn't too happy with the connection between the bladder and drinking hose. I'm concerned may break someday.But.... It's a more than fair price for it. It's worked fine so far.I look at it like this.... Even if the bladder breaks someday, I still have an insulation pouch and a pretty decent cleaning kit for under 20 bucks which I can use with my replacement bladder if I need to purchase one.But so far so good. The system is working above innitial expectations.Good luck with your purchase. --- ## 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/56795657-3l-hydration-bladder-water-reservoir-pack-for-backpack-3-liter](https://www.desertcart.co.uk/products/56795657-3l-hydration-bladder-water-reservoir-pack-for-backpack-3-liter) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
