I've got one of the newer Vapor Trail packs that has a internal pocket for a platypus. Dimension wise it looks like it would just barely fit a 3L Platypus Big Zip hoser, but it'd be tight.
I know a 3L would fit (or even something larger) between the backpanel and the bag, but I was wondering if anyone has actually used a 3L in the pocket inside successfully.
The inside pocket is between 7.5 and 8" wide and it is just about 17" to where the hole for the hose is... The 3L plat claims to be 7.5 by 17 online...
Anyone with some experience on this?
