Lightweight Insulation Hiking Pack Tactical Backpack Women Men Hydration Day Rucksack for Cycling, Running, Climbing, Camping, Biking Review: Muy funcional y de buen tamaño Review: This is a great backpack! Super happy with it. It’s very comfortable and has tonnes of space and pockets. I really like how there’s a built in rain cover (haven’t had to use it yet). I initially thought the water bladder was faulty because it leaked where the straw connected, but it just wasn’t tightened enough!

Pull it out fill with water and go. **Q: Can the bladder be taken out?** A: Yes, the bladder can be removed. I didn't like the bladder that came with it, I couldn't get rid of the plastic taste. I replaced it with one that has two hoses. Love the backpack. **Q: Has anyone had any issues with adding hydration packets (Liquid IV, Gatorade, LMNT, etc..) in the bladder?** A: None at all. I used both Liquid I.V. and Mio. I do rinse it as soon as I get home. I use this to go to Disney World, and works great!!! Good tip is after you rinse it roll the bladder and put it in the freezer. Won't have to worry about mold growing. **Q: Is the hydration tube freeze in cold weather? Most hydration pack tubes freeze on the mountains for skiing & cannot drink from it anymore.** A: It will freeze as any other product would in freezing conditions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***. on 6 February 2026* Muy funcional y de buen tamaño ### ⭐⭐⭐⭐⭐ Review *by A***R on 20 March 2026* This is a great backpack! Super happy with it. It’s very comfortable and has tonnes of space and pockets. I really like how there’s a built in rain cover (haven’t had to use it yet). I initially thought the water bladder was faulty because it leaked where the straw connected, but it just wasn’t tightened enough! So make sure it’s fully fastened before you head out! ### ⭐⭐⭐⭐⭐ Review *by J***N on 25 August 2025* Update: 9/10/25 I wore it for several hours, (in extreme heat and two days in rain) at a WEC race where I walked for miles and had no cover overhead (from sun or rain.) It did not disappoint. The water repellent bag in the zipper pouch on the very bottom is a great idea. Given the packs small size, you can load it up pretty good. The straps and padding and material are all excellent. It's comfortable even with a considerable load. The pack itself is light weight. There's a strap at the chest and one at the waist if you desire to use it. I found the waist one actually helped bear the weight. My original review (before using it) is below: I might come back to give it five stars, but I haven't used it yet. I've never had one of these (of any brand) so I can't compare it to anything else. The main thing, the bladder, is constructed well and rests in an insulated compartment, (as the description says.) I will be wearing/using it a lot at COTA in Austin TX in two weeks and if there's an issue it should show up then. The breathable straps and padding exceeded my expectations. There are other pouches or pockets to store other smaller items. In the largest pocket I can carry my foldable chair. Surprise! With the bladder (two-thirds full) and the chair the entire rig weighs 10 lbs. Not bad for hiking or longer walks. If you are a runner, you won't want to pack so much, certainly not a folding chair. The materials don't look/feel cheap. The attached straps (one at the waist too if you want it) are easily adjustable. I can see where it's lacking anything. We'll see, soon enough. ## Frequently Bought Together - Everfun Hydration Backpack 18L with Water Bladder 2L/3L Hiking Water Backpack Women Men Hydration Pack Insulated Lightweight Day Hydropack with Storage for Hiking, Biking, Running, Festival - Trekology Trek-Z Collapsible Hiking & Trekking Poles - Balance Support for Seniors, Women, and Men, 2pc Per Set - LHKNL Headlamp Flashlight, 1200 Lumen Ultra-Light Bright LED Rechargeable Headlight with White Red Light,2-Pack Waterproof Motion Sensor Head Lamp,8 Modes for Outdoor Camping Running Hiking Fishing --- ## 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.gr/products/478378773-hydration-backpack-18l-with-water-bladder-2l-3l-hiking-water](https://www.desertcart.gr/products/478378773-hydration-backpack-18l-with-water-bladder-2l-3l-hiking-water) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-30*
