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

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

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.

I bought this hydration pack for my husband. Overall he said it works well. The bladder hose disconnects and the pack still holds water which it a nice feature especially if you wanted to refrigerate your water night before. He's used it 3 times and so far no leaks. The actual pack is light weight, I worry a little bit about the durability of it over time. It has ample pockets in the back but nothing on the front of the pack so it needs to be removed to access. Overall a good purchase for the price point

I like how it holds 3 liters and has all these pockets for different items. The straps are wide and comfortable, and there are a few latches to make sure it doesn't fall off of you. I only use 1 just to be sure

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

While this pack is durable and holds plenty of water, the zipper quality is questionable, and the bladder is not confirmed to be BPA-free. I recommend looking for a safer, BPA-free alternative. The straps work well and you won't have to worry about the hydration pack moving all over the place.

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.

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!
