Heli Pro DLX or Pro II?
I was trying to decide between this and the Pro II Backpack. The tag on the Pro II showed that it has the vertical snowboard carry. The tag lies. The Heli Pro DLX has the vertical carry.
The Pro II has a back entry area that to get into the main compartment. The top zipper doesn't open very wide and is quite annoying. It is even more annoying if you have a hydration bladder in there because the hose will be in the way. The other pocket is nice though because it has a holder for your shovel handle and your probe to keep them organized and the shovel blade fits in there too!
I like the Heli Pro DLX better because it has the vertical snowboard carry option if you don't want to carry your board vertically, the top zipper opens as far as a normal backpack does, and has a deployable drink holder on the side. It isn't as organized withe shovel and probe as the Pro II, but the other features make it ok.
