Are there backpack types/systems that would allow to both conveniently carry snowshoes and ice tools?
I always find that packs with good ice tool attachment system simply have no place for snowshoes. In the scenario when you walk in crampons or micro-spikes, the only place for the snowshoes is on top of the pack blocking the access and also making your profile wide. When the rope is thrown into the mix, this makes for a logistics disaster.
This is not an uncommon scenario though and there must be a solution. Nevertheless ski-mountaineering packs for example have good attachment for skis/snowboard, but are usually too small, climbing packs have no room for snowshoes etc.. Perhaps there is a category of packs for the application or there are features that help to identify possible candidates?
More details about the pack requirements:
Day-trips, not extended expeditions. Current pack Millet Axpel 42, a couple of Petzl ice tools + ice axe, MSR Lightning Ascent snowshoes, 50m Petzl rope, crampon bag, ice screws. Lots of things to be kept outside the pack. Winter conditions can be very cold and windy, so have to carry a serious down jacket.
A PROPOSED ANSWER, LOOKING FOR FEEDBACK
I believe that in a climbing specific pack, the single most important extra feature that helps carrying snowshoes, ice tools, rope etc. as described above, is long compression straps with reversed buckles; see for example or some photos I made for this purpose. When configured this way, the compression straps can be lengthened and wrapped around the pack to attach snowshoes, pickets and what not. To my knowledge at least two companies (Gregory and Mountain Hardwear) make packs with reversed buckles and many other do not. Not sure why and what the downside of reversed buckles is.
Other such features are having a side access to the pack (because the top is blocked by the rope) and two lid straps so that the lid buckle doesn't get blocked when the snowshoes are attached.
