Better than it seems

So, first off, it DOES hold 2 liters. You just need to take it out of the case first. There's a zipper at the top, and you can push the circle lid through the hole in the case. There are fill markings on the bag, though the 2L mark isn't as clear as the 1L mark. Regardless, I took a measuring cup to it and filled at least 2L.

Since I have not found any feedback of using this in cold weather, I will say that dropping this in an REI Flash pack and taking it through 32F snowy woods for a few hours kept it from getting freezing cold. I blew air back into the tube so that there wasn't any remaining water in there to get super cold. I have not tried it in hot weather yet.

The 2L version of this pack fits great into a Flash pack's pocket for water reservoirs. 3L not so much (a bare 3L bladder works fine, but not one with the thermal case), and since I almost never need that much water (and if I do, I'll bring extra water bottles) I went for the 2L.

When you remove the bladder to dry it, there are these claws that normally sit around the opening that fold down to keep the bladder open to air out. Also, there is a short "wall" connecting both sides of the bladder, which help keep it slim so that you can slide it in the thermal case easily. The handle on the opening is quite comfy/useful, and lightweight.

Disconnecting the quick-release hose (given that the hose is empty) amazingly does not leak weater all over the place. My only gripe is that the buckles on the case don't come off, since I don't really forsee me strapping the bladder onto the outside of a pack. Nice that they are there, but I wish they were removable. Maybe they are, and I just haven't figured out how to do it yet.

Great Insulation! Size Confused.

The insulation is excellent, it keeps the cold stuff cold for a long time. The only thing that confused me was that it seemed full after dumping two 16.9oz water bottles into it 34oz is about half of the 70oz listed on the tag.

Great insulation, incorrect volume

I own three of the older version insulated camelbaks (2L and 3L) and they have been awesome. I was excited to get this new version with the 1/4 turn cap and quick connect tube. After bringing it home and filling it up I thought "There's no way the tap was on long enough to fill up a 2L bottle." So I took out my Pyrex measuring glass and the camelbak was overflowing after just the 3rd 500mL dump (1500mL = 1.5L).

I wonder where CamelBak gets the extra half liter?? I will be taking this back and seeing if the 3L is really 2 or 2.5L

size not correct

It does not hold 70 oz. I can barely get 60 oz inside; very sad. It is a better size than the 100 oz, but I may have to trade up.
