In reply to Removed UserGRUMPY MONKEY:
What you want seems to be a climbing sack, that is not made for climbing... All the specs, bar fat (instead of tall & thin) are normally the stuff you find on climbing sack.
So your best bet is actually a "cheapo" wannabe hiking sack... but generally they're shite.
Moddin' the heck out of a "cragsack" might also work, but again a lot of work.
Or you accept the fact that they sacs tend to be a tad tall & thin (ie. slim) and then pick the one that suits ya the best.
In which case I would suggest the Blue Ice as well.
If you forget the skis, a ~50l haulbag might suit ya as well. Tough as nails, and you can cram everything in, including axes. For the record, that is my "sack" for the stuff that does not require clim´bing with said sack...
