I have the women's version of this bag and absolutely love it. I use the pack mainly for day trips. It holds plenty of water for a full day hike and has enough space for extra clothes, food, emergency supplies, etc. The front pocket is divided up into zippers and pockets and holds everything perfectly. A zipper pull broke off on first use but CamelBak agreed to ship me a new one, no questions asked. The reservoir is easy to use and clean. I would recommend a cleaning kit just for the hooks it provides - this makes holding the reservoir open for draining much easier.All in all, wonderful bag, perfect for day hikes.
This back pack is great for day trips! I have a 3L bladder which came with mine and it works perfectly. Its all about comfort when it comes to backpacks, and for a smaller pack it provides allot of it. Straps are great, zippers are very durable and it is even a tad bit water repellant. This was a great purchase for me!
