This was a Christmas gift for my brother and he absolutely loves it! He was looking for a Camel back with space for storage like a small back pack and he was so excited about this product! He hikes a lot and goes into he mountains and says it's perfect!

I recently was in a bike ride for charity of 150 miles. My pack was the envy of the other riders. When we stopped I had snacks to spare. When there was trouble I had the tools and the spare tubes. It fit everything I needed and that was when it was compressed. I still had the option to hold more. It is one of my fav pieces of equipment. I will now start taking it hiking and everywhere else I go.

I love this hydration pack. It's prefect for long day hikes and summit attempts. I like how you have the option of having more or compressing it to Mule size. I'm buying a Blowfish for everyone in my family!

I have had a Camelbak Blowfish for 4 years now. It is far and away the most used piece of gear I own. It looks like they have made some improvements to the one that I own. Like the air director panel and the better reservoir. One of my favorite features is still there and that is the expandable big pocket. That is so handy. I use it mountain biking, hiking, going to the park, sporting events, and many other ways. Having the expandable pocket allows for customization depending on the use and the logistics of that use. I open it up to add rain gear or food depending on my activities. You won't be disappointed with the blowfish.
