....or scrambler's rack.
When I started to get around the classic ridges and buttresses more than fifty years ago we just tied onto a hawser-laid rope with a bowline and carried a couple of rope slings and some steel biners and used a waist belay, usually, if possible sitting in a braced position with the feet and using a good high anchor.
Moving together came much later on.
Nowadays with all the great kit around that really you shouldn't be without.....harness, helmet, superb ropes, belay plates, 'the fear gear'....rocks, a couple of tape slings and a few quick draws. etc.
You don't need to overladen yourself....just try to measure what is needed for the type of terrain you intend to travel through.
Direct belays using Italian hitches can be useful also by arranging the anchor/and the loop for the HMS biner and It. hitch and your own tie-in with a clove-hitch...flexible... can be useful on shorter 'single pitch' terrain....you are then much free-er as Mr/Mrs belay person.
Now what have I missed out.
help needed!
