While I did not optimize for the weight of each item, I made sure that I'm generally not packing too much and that the pieces, especially the heavy ones would be quite versatile and not just useful in specific situations.
I was traveling for more than 6 months from Southern Italy to the Shetland Islands. This meant that I had quite different weather, especially in late Winter and higher altitudes. The clothes I packed would need to support me in all these conditions.
Another factor for me was to see what I already had. Generally, I tried to buy as little new clothes as possible. That's an attitude that I generally have, I really don't like to equip myself for every adventure and try to take good care of and repair the things that I already have. It's a waste in terms of money and more importantly resources.
Looking back at the trip I feel that I packed really well. I have one item that I should not have brought. A self-knit silk mohair sweater. It was absolutely too delicate to be packed and unpacked each day, and I sent it home as soon as the opportunity came. Below you find a list of all the items that I brought. And while I did not worry too much about the weight, I still measured everything before.
