  • Great Hydration Pack – Comfortable, Durable, and Roomy!
Color: Arctic Blue
The media could not be loaded. I bought this hydration backpack for weekend hikes and it’s exceeded all my expectations. The fit is incredibly comfortable, even during long treks. The shoulder and chest straps are adjustable and really help distribute weight evenly. The water reservoir is easy to fill and doesn’t leak at all, and the bite valve delivers water smoothly without needing a hard pull. I also love how much storage space there is—it fits my snacks, phone, keys, sunscreen, and even a lightweight jacket. The back panel has good ventilation so I don’t get too sweaty, even on hot days. Honestly, for the price, the quality is fantastic. Highly recommended for anyone who enjoys outdoor activities! ... show more

  • Great pack, difficult hydro-bladder
Color: Red
The hydropack is great, fits well, easy to use, and it's lightweight. The hydro-bladder tho is hard to clean and refill. Needed to make a hook to hold it to refill.

  • Keeps cold, even in the scorching Caribbean sun!
Color: Red
The single best thing I have bought for traveling! It has been a life saver for hikes, hanging out at resorts, beach trips, kayaking, etc. Always put some ice in it and it keeps it surprisingly cold for hours, even in the scorching Caribbean sun! Not much extra room in the pouch, but enough to hold some sunscreen and snacks. ... show more

  • Sturdy and keeps me hydrated
Color: Navy Blue
This was my first hydration pack. It has held up to miles of hikes without fail. My only grip is that it is a little fussy to feed the tubing through the top of the bag, but I do like that it was convertible for left or right handed use.

  • Great Pack!
Color: Black
Great pack. Son took to a music fest with 100+° and worked like a charm. Nice pockets to keep stuff secure. Highly recommend.

  • Great Bag, Terrible Bladder
Color: Arctic Blue
The bag itself is great. Perfect size and feel for long bike rides. Pocket easily fits a cell phone and some small snacks. Pretty comfortable and I forget it's on my back. The bladder, however, is bunk. First, it is the first bladder I have ever had with no handle. So I have to stick my hand in the hole to have a grip and leverage to fill it. Then I have to hope I don't spill while I am screwing the cap on. Second, where the hose connects to the bladder has no drip stop if the hose is not connected, so water just pours out. Also the first time I've run into this with a bladder. This makes it more difficult to fill the bladder outside of the bag because you always have to pull the hose out. Third, the cap over the mouthpiece doesn't click closed, so it just flaps around open, leaving the mouthpiece exposed. Finally, the mouthpiece slides right off when you are drinking, stopping the water from coming out. I constantly have to drink, push the mouthpiece back into position with my thumb, then repeat. Because I like the bag so much I've just swapped the bladder with one of my other ones, but a bit disappointing. ... show more
