CamelBak CB-1718901000 3 Liter Mil Spec Crux ThermoBak, MultiCam

I bought this a little while back, and I have gotten to use it several times since then. Key points that I wanted it for: 100 L capacity, heavy duty, and MOLLE compatible. Also, it is insulated. And let me tell you how that works. I filled it with cold water and went on a hike. It was about 98° out. I probably went through about a liter and a half during the hike. I then put it in my car, and spent some time with my girlfriend. So this sat in my car baking for several hours while I was having dinner. On my way home, I realized I was thirsty reached over and grabbed the tube. The water Was still cold! Very well made. But remember, this one is hydration only pretty much. Not much room for anything else. Maybe a folded map. But the system is amazing.
