A good will suggestion for your porters. Take some of your "older" hiking/climbing gear including worn boots to give away to your support team, the porters. Of course by the looks of your gear in the photo, you may not have any room!!
At the start of our Kili climb I looked for the porter with the biggest feet and told him that after the climb he could have my size 13-14 Nike Approach Boots. He was thrilled even though he appeared to have only a size 11 foot.
All our group gave away most of our stuff, unwashed after 6 days on the Mt & all the porters were very appreciative.
