My husband and I bike and hike and well do everything outdoors, so this was the perfect gift for him. I have a camal back that I have been using for awhile, but there is no where to store anything... with this bag, not only can you have your water, there is plenty of storage space. (first aid kit, bike repair kit, the things you should have you just never have room to take!)

I've had this pack for several weeks now and have taken it out a few times already. It is light and has become a staple to my riding attire. The only negative is that the tube got a kink in it when it was shipped, so I have had to work that out over time. Works great now. I'm glad I didn't waste my money on a CamelPak.

The backpack is a great little bags for day hikes. Its very comfortable and has lots of small pockets to store things. Thanks Overstock!

There isn't much room for anything else. Works great for a hydration pack, but doesn't have much storage room. Maybe fits a jacket and small items (keys, cell phone, etc.)

This pack is very convenient because not only does it provide a place for a refreshement for outdoor activities. It also has a place for all other nic-nacks that are needed when excersing, biking, or running. Room for keys, hair ties, and a towel. Great price for a helpful product.

used this pack on a three day weekend. only refilled once. lasted long time. easy to use. liked this pack

The mouthpiece fell off the first time I tried to use it. Also, the books that I put in the backpack got wet. Not meant for skiing because it freezes up. Maybe it would work better if put under your jacket.

I was pleased that it matches my husbands dirtbike, he was pleased that it looks sturdy and easy to handle. If I had need for one myself, I'd consider this one first.
