Outstanding hydration pack. I use it everytime I ride my bike. It works great when road riding as well as mountain biking. I have hit a few trees with it and it stands up to the abuse without any damage. It is very comfortable and has more than enough storage space. It also works great when snowboarding. The insulated drinking tube is standard and keeps your liquids cold or hot. In the summer my camelbacks allow the water inside the uninsulated drinking tubes to get uncomfortably hot. And in the winter, the water freezes. I own two Camelbacks and a Gregory Pack but the Blackhawk Tsunami is my favorite and the one I use the most. Getting ready to buy for my son.
Pros: Comfortable, carries large amount of water
Cons: doesn't have a waistbelt
