Beginner buys, what do I need?

Hello, since a pretty big shop near me now after season end offers quite a percentage I would like to buy my first equipment. Will once (distance) and as much as possible get everything. Nothing is available. I just don’t want to forget anything, so what do I need and there are certain details to pay attention to? For the time being only about relatively short tours, i.e. suitcase/tank backpack outside. So far I came up with the following: – Gloves – Shoes – Helmet – Jacket/hose – Kidney belt – Oil B in grateful for all tips. LG Haasinger
