In reply to due: I have an X-Pod and a Black Ice as well as an older Crux AK47-X. The X-Pod is excellent, weighs about 2.4Kg, but I can carry comfortably 20+Kg with it. Simple and bomb proof. ditto the Black Ice.
Not so convinced about the Crux, the floating lid is very badly designed and the straps slip.
I originally had an Arcteryx Bora 95 for expeditions, super comfortable with big loads but very heavy and some features seemed pointless. The X-Pod is nice and simple and has only the features I needed.
So far my feelings are that if I need to replace the X-Pod then I will get another of them.
