What was in Rei's locker?

We have been made aware since the beginning of Rome's Revolution that the passengers aboard the Ark II were very limited in what they were allowed to bring on the trip. The problem was weight and having enough fuel to make it to the stars.

In The Ark Lords, we found out that the actual weight limit was 20 kilograms which equates to about 44 pounds. So what did Rei take that weighed that much?

It was mostly clothes. The clothes themselves were vacuum-sealed to preserve them and guarantee that they took up the minimal amount of room. In addition to regular clothing, Rei had the super-exotic version of a Gortex jacket as well as an ample supply of underwear and socks. He also brought along a number of polymer books because nobody thought that paper would last several centuries.

He also brought his tablet computer and his music slab and earbuds. He also brought a lightweight, collapsible transit:

           

Rei was a general purpose engineer and surveying was one of his jobs. In addition to the transit, Rei also brought along eating utensils, a polymer mug, a ceramic knife and an all-purpose tool kit.

The only thing he did not bring, which he eventually came to regret, was a pair of sunglasses.
