Vibrelli Hydration Backpack & 2L Hydration Bladder - High Flow Bite Valve - Hydration Pack for Cycling, Running, Hiking

I've been using this pack for cycling instead of carrying water bottles and I love it, I've had it 1.5 years and I cycle 10 miles twice a week religiously. The bite valve is high quality and works well, the pack itself is sturdy. Yes, it can be a bit awkward to fill but once you've done it a couple of times you get a system going. I freeze the bladder with a cup of water in it between rides to prevent mold/mildew build up and that works great for me. Don't hesitate, this was a good purchase!

Great product. Light weight and I use daily. The quality is very high and at a great price point. Would recommend to friends and family.

So I bought this for skiing, and overall I really liked it after a week of daily use. The only other brand I've used is Camelbak, so I'm going to compare it to one of those. First, the price. This is less than half the price of a comparable Camelbak product, and while this product isn't as high in quality as that one, it is an excellent value.Back itself - It is a very lightweight pack and seems sort of flimsy compared to the typical camelbak. The straps in particular are thin and I would not expect this to survive more than one season of regular use. The straps around the chest and belt seemed to loosen themselves a little after a whole day, which wasn't great, but it's a small enough pack and I wore it under my hard shell so this wasn't really a big deal. Putting granola, phones, small items in it worked fine but if the pack is full of liquid it doesn't leave much room. It was comfortable enough and under my hard shell I could forget I was wearing it (once the bladder got a little less full).Bladder and hosing - The fill opening on the bladder is much smaller than a Camelbak opening - this is ok but I can't get my whole hand inside if I want to clean it. Not a big deal, but the other brand uses bigger openings. The bladder sits in its own pouch on the back and the hose just snakes around to go to the sleeve on the straps. It does not quick-disconnect from the bottom of the bladder, which is a bummer because that is a nice feature for filling. A few times I tried to fill it and because I didn't want to snake the whole hose out I ended up with water on my pack - right where it contacts my back. I learned how to prevent this but the first few times it was tricky. The hose itself was fine, and seemed strong, but I had to snake it all of the way across my chest to get it to sit in a convenient position. It had a nice clip to hold it there but that clip does lot look like it would survive a good fall right on top of it. The bite valve was great, worked perfectly, and the cut-off switch was pretty easy to manage with one hand. It was a little tougher to open than close based upon its design but overall I was pleased.I would recommend this product for anyone who wants a low cost hydration pack and doesn't need something terribly rugged or that will get every day use.

This is exactly what I've been looking for the last 5 years. I've been holding out for the perfect hydration pack and this is it. I ordered a second one recently.If you fill the bladder completely, there's little room for much else in the main compartment, but if you fill it to 1 - 1.5 L, then there's still room for a granola bar, wallet, small first aid kit, sunscreen, keys, etc. Plus there's the outside mesh pocket. And you can strap a layer (windbreaker, etc) to the pack with the bungee. The longest hike I've done with this is 5 miles, but I'm taking it to the PNW with me soon and expect it will do well even for 8+ mile hikes.If you're really short like me, you might need to move one of the pieces (up) that secures the chest strap, as it falls right across the bosom. But otherwise, this is perfect for small folks. My regular sized hiking pack is just a backpack and it feels too big on me. It covers too much of my back and my butt which causes me to sweat more. I'm always pulling it up. From now on, I'll only be wearing my regular pack if I'm on an all-day hike where I want to bring lots of food or more than 2L of water. This new pack is my go-to.

UPDATE: I ordered a well-known competitive brand to replace this one and had similar issues. I found a video suggesting to rotate the cap in the opposite direction first until it clicks, then to tighten it. Although it didn't help on the other pack, I went back and tried it on this one too - bingo!! I used it for 3 days at a music festival and it worked out great! I'm upping my review and think it deserves 5 stars for the price. My only remaining complaint is that the Velcro stuck to the fabric and started to mess it up a little, but it's not a big deal given the price.Original review:This appeared to be a well-made little hydration pack / backpack and I was excited to try it out before using it at a musical festival in a few weeks. To start, it was pretty cumbersome to remove the bladder from the backpack and then to angle the opening under a faucet to fill it. once full, I noticed some leakage from around the cap, which I ignored and hoped would get better. It only got worse. I put the bladder back in the bag (also difficult once full) and water started pouring out from the bottom of the bag, all over my kitchen. I set it down to clean up, and even more water was pouring out from around the cap area. The cap was twisted as tight as it would go, but there was a steady leak from the bottom. Sadly, this is a total no-go.
