CamelBak

First time I used the pack was at a trail work party. It carried my water, food, bug spray, TP, jacket, another shirt, and a few other items. Plenty of room and fit great.

Just started using this back. It is just what I wanted for hikes that last less than a day. I can get emergency materials, extra socks, rain gear, food and other essentials for a 4-6 hour hike. It is comfortable and easy to use.

Bought as a gift - my friend loved it and her sister is jealous.

This pack is the ideal size for day hikes. There are enough little pockets to keep your small stuff from migrating to the bottom of the bag and larger areas for layers, lunch, etc. It adjusts easily and is pretty comfortable. I also really like the new water bladder design. There were no leaks and it is a lot easier to open and close.

I bought this for when I go for runs. I get thirsty, but I don't like to carry a bottle in my hands, so I thought this would be a good solution. It is comfortable for hiking or walking, but as soon as I started running, the pack started bouncing around my back. I tried wearing it tight around my hips, then I tried it tight around my waist, but it didn't matter where I wore it or how tight. I ended up carrying the bottle in my hand to stop the bouncing, which defeated the whole purpose of buying the pack. Also, the band that keeps the extra length of waistband in check does not stay in place, so that extra bit of strap flapped around and chafed my arm as I ran. The bottle itself is excellent, and the pack has a lot of space for keys, ID, money, or snacks.

This was a perfect size for me @ 5'2".

My son's troop highly recommends camelback products.

These water bottles are great for cycling. They don't spill over big bumps with valve open, so you can ride with the valve open at all times.

I have an ankle injury that prevents me from walking or running for outdoor exercise. I love biking and usually I'm out for an hour or so per ride. This size is perfect for that timeframe. I can't get a bottle mounted in the right location on my bike to avoid dismounting to sip while I'm riding. So this is the perfect solution to sipping and keeping my energy up during a ride.

i have been using this for 1 to 2 hr bike rides since I received it a couple weeks ago. I plan on using it for longer 3 to 5 hr rides and hiking. i love the double strap, it is very comfortable and stable. I love the size. It holds some snacks, layers (its spring and weather is unpredictable), phone, anything you might want on a day trip.
