In hiking mode, the kit is carried on a Scopac. Circular polariser and neutral density (ND2) filters are also used when conditions demand them. I carry about 200 gigs of memory on several separate cards. I generally shoot in RAW. For slower moving subjects, I switch to 14 bit which adds about 10% to the file size. Lightroom CC is used to process the images. I also use Adobe Light Room.
If space and weight allows on foreign trips, I take my laptop (Surface Pro 4) and download all images each evening.
