What are some gear you always keep on you?

so I was playing the other day when I realised I have some MASSIVE holes in my load outs. like I realised that I used NinjaBike and Momento so much that now I'm using the Tinkerer more I have no High-End Backpacks at all

so my question is. what gear do you always have on hand? like if you're putting together a build but maybe don't have all the pieces or just don't know what to put into what slot, what's something you can just put in there and it works?
