You can clean the hose with a long handled, narrow bottle brush. The hose unclips from the bladder which means you can directly clean as much of the hose as your bottle brush will reach. There are several suitable bottle brushes available on Amazon. Searching for "Munchkin bottle brush" will return some good options. **Q: What proof is there that this is pba free and will it fit in my walmart ozark trail outdoor equipment backpack?** A: the test report release by SGS, Report No. is GZHG1411043611SP.and we don't know if WACOOL 3L bladder will fit in your backpack,you can measure the backpack`s interior space and then compare it with our bladder's flat size. **Q: What's the trick to make this thing stop leaking? Carried it hanging in my ruck, and the bar separated from the bag. Screw top also leaks...** A: Make sure you slide the bar tightly against the bladder's plastic top, doubled over. Don't touch the bar while hiking. I don't know why the screw top leaks. Make sure you tighten it securely. . ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made, high quality and durable. Used for hiking/ backpacking and biking *by on Reviewed in the United States 20 August 2016* The item is well made and the materials are of excellent quality. First of all the seams are well made and can hold up to the stresses of hiking and biking. The top slides off to allow for easy access and drying.The top holds up well and will NOT slide off while using, and will not leak. I like the insulated hose because it does not condensate which is a big plus because of dusty conditions that sometimes occur during hiking or biking. The attachment mechanism is simple and holds well. The water will not leak out when the hose is removed, it will only come out when the hose is attached. The bite mechanism works well and the hose lock works fine.Recently took it on a 10 mile hike and put in cold fridge water at around 8 AM. The water was cold ALL day even at 8PM when I was back home. Functioned well and there was no after taste. (NOTE): rinse the bladder with a 7% saline solution and some warm water. This will remove any chemical taste.NOTE TO MANUFACTURER: Please fix the dust cap (cap that covers the drinking region) it keeps coming off and does not stay clicked into place. I went on a 10 mile hike and it got dusty at times, my cap came off and dust was all over the drinking part. I would recommend harder plastic cap that clicks in and stays in rather than the softer cap.Edit: 03/2020Works great to this day and I’m afraid this is the only water bladder I will ever need for the foreseeable future. It’s in the same condition as day 1. Bottom line is that it is of great quality and if you rinse it out after use and line dry it, it will take care of you. So far it has been on multiple hiking trips and never let me down. 3L is a wonderful capacity and should be enough for most hikes. Max hike I did was roughly 20 miles in the summer and 3 L was enough. (I’d carry a filter just incase). Overall very happy with the product. ### ⭐⭐⭐⭐⭐ Something you must have when you go on a hike *by on Reviewed in Australia 1 February 2019* This is a great bladder. I have used it about 5 times now and it works as expected without any leaks. It is really easy to fill because it has a plastic handle around the opening where the water goes in, which keeps the bladder stable while you are filling it up. The bladder also really easy to clean. All you need to do is to unscrew the top and unhook the bladder entirely.I also really enjoy the quick connector of the tube from the bag. It doesn't leak at all and makes it much easier while cleaning the bag or filling up. I will buy more of these when I am back in the market. So glad I got this! ### ⭐⭐⭐⭐⭐ Worth the price, no leaking, no plastic taste *by on Reviewed in Canada 31 May 2023* Bought it for a trek. The opening on top was very useful. ## Frequently Bought Together - WACOOL 3L 3Liter 100oz BPA Free EVA Hydration Pack Bladder, Leak-Proof Water Reservoir - WACOOL 2L 2.5L 3L BPA Free PEVA Hydration Pack Bladder Leak-Proof Water Reservoir - Hydration Bladder, 1.5L-2L-3L Water Bladder for Hiking Backpack Leak Proof Water Reservoir Storage Bag, BPA-Free Water Pouch Hydration Pack for Camping Cycling Running, Military Green 1.5-2-3 Liter --- ## 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.kr/products/94867365-wacool-3l-3liter-100oz-bpa-free-eva-hydration-pack-bladder](https://www.desertcart.kr/products/94867365-wacool-3l-3liter-100oz-bpa-free-eva-hydration-pack-bladder) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-10-27*
