2 Pack Hydration Pack with 2L Backpack Water Bladder - Great for Outdoor Sports of Running Hiking Camping Cycling Skiing

I recently started walking/running and would get tired of having to carry a water bottle, phone, keys or <insert other item you carry here>. I found this bag as a good alternative to keep water on hand and less "do I have everything still or did they fall out?" The bag is nice, and adjustable to help hold tight to my body, but not too tight, thus keeping the bag from bouncing up and down. There are two zippers that provided good "locked" storage so nothing falls out, and holds well enough for items mentioned above. The bag holds enough water for me to re-fill every two days (I normally walk every Mon-Thur for about 1 hour or 3.1-3.5 mi). The opening to fill up the water can get somewhat stuck or rather is difficult to open, but not the breaking point of this item. I would recommend this product for use!

Not much to say about it. It gets the job done. Easy to carry, very comfortable also easy to use.

This product is a fantastic choice for outdoor enthusiasts, and it’s clear a lot of thought went into its design. The storage capacity is generous, with well-organized compartments that make it easy to keep your essentials accessible. The fit is comfortable, and the adjustable straps ensure a secure feel, even during vigorous activities. I was especially impressed by how lightweight it feels, even when fully loaded. The hydration bladder is easy to fill, clean, and use, with a well-designed hose and bite valve that work seamlessly. The materials used throughout the pack feel durable and built to last, making it a dependable option for long hikes or cycling trips. That said, there are a couple of areas for improvement. On cold days, I noticed a lack of insulation between the bladder and my back, which can be uncomfortable as the cold water chills the area quickly. Additionally, the connection between the bladder and the hose could be more secure—it sometimes felt a bit finicky and prone to slight leaks if not handled carefully. Overall, this product is a great investment for most outdoor adventures, but addressing these small issues would elevate it to an exceptional level.

I love this thing. It took me a day to figure out that there is an open and close on the mouth piece, but after I found it the happy dance began. My walks are more satisfying. Im looking forward to taking it out on my next hike.

I bought this to use for La Ruta de los Conquistadores, "the hardest mountain bike race in the world", because I needed a very light 2L pack. This pack worked well. I actually changed out the hydration pack because I wanted a bladder where the nozzle had a cap that completely covered the mouthpiece, because on this trip you ride through cow dung and so forth and I didn't want it flying up onto the mouthpiece. So, I bought this for the pack itself, not even the bladder, and I still think it was a good price. The bag is well designed with one of the zippered pockets going to the bottom and the other terminating in line with the end of the mesh pocket. The mesh pocket is very useful to stuff a jacket in there, or your used bar and gel wrappers, etc. The one thing I would change is the way the chest straps are setup. They have 3 loops so that you can put them higher or lower, but I had them on the lowest setting and it still wound up too close to my neck. I also had to tighten them as much as possible. Anyway, it worked well enough. The reason that I bought this pack instead of other similar ones [This appears to be one of many sold on amazon with different brands that are essentially all the same pack] is because it has the waist strap as well. The others did not seem to have the waist strap. This is useful especially for mountain biking when the pack bounces up and down on your back. Less necessary for road biking.

Its ok. For the price it does what I need but the cap is really hard to get a good seal with and it'll leak. It also gives off a lot of condensation and goes through the backpack which for me riding my bike is fine but if someone doesn't want to get wet then you should know it does this.

I’ve been using the Baen Sendi Hydration Pack with 2L Water Bladder for running just now and overall it’s been a solid buy—especially for the price. What I like: Very lightweight – Once it’s on, I hardly notice it, even when running. No annoying bounce thanks to the adjustable chest and waist straps. Comfortable fit – The straps are easy to adjust and keep the pack snug. Works well for jogging, trail running, and biking. Good water capacity – The 2L bladder is plenty for 1–3 hours of activity. Decent storage – Enough room for keys, phone, wallet, and a small snack. Great value – Compared to more expensive brands, this does the job at a fraction of the cost. Things to be aware of: The bite valve takes a little getting used to. You need to bite firmly and suck at the same time for good flow. The back panel doesn’t have much ventilation, so it can feel warm during hot summer runs. This is more of a casual to moderate‑use pack, not something I’d choose for ultramarathons or multi‑day hikes. The shipping speed is super! Got it within 18 hours.

It’s very light and does what it suppose to do!!!!
