You could add a lot of things depending on what you believe would come in handy.

I would :

o Replace the cotton white socks with wool socks (merino wool
blend) and the small light with a cheap headlamp

o Lose the medic shears and replace with a medium size Swiss Army knife

o Remove the playing cards (needlessly heavy!) and replace by a pouch of Gatorade crystals

o Replace the N95 masks by a bandana (such as the Buff). Your masks will lose their shape and might become unusable after a little while in your pack.


There you go.
