I'm not sure if it's a front zip into the main pack, or just a zip open front pocket... given POD's reputation for gnarly, strong packs I suspect it's the latter. My Gregory Juxt daypack from 3 or 4 years ago has a pocket like that (a butterfly pocket I think they call it?), really useful too.
I'll be interested to see these. I wonder how the 50 litre Granite compares with the existing Black Ice, my favourite pack ever (as in 'if I could only keep one pack, that'd be it
).
