I was really disappointed with my insulated tube. Especially for[$]. I havn't noticed that big of a difference in it keeping my water unfrozen during winters or cool during summers. If anything, it makes the tube harder to store and I end up having the entire length of the tube hanging out so if I want a drink I have to fetch it. It makes it so stiff and the tube is way to long to properly manage. It's also a pain to get in the backpack - you have to disconnect it from the bladder and then reconnect it every time to get the bladder in and out.

I used this with a 2L Platypus Big Zip reservoir. It was simple to install on the bag.
You have to buy a clip because all you get is a hose.
I used this on a 7 hour day hike in 80 degree weather. I had my 2 liter Platypus bag in the refrigerator a day prior to the hike to make sure the water was cold. I could tell a difference in the water temp compared to the standard hose. The difference was only slight. Maybe around 20% cooler. So, the water was still warm...
If Camelback didn't make you buy extras and charge a lot I would have rated it higher. It'a just way to expensive for using in hot weather. Maybe it's better in freezing conditions.
