For lack of a cargo container, Trey had to improvise. He got the tools. Whether he'll be able to get them through the airlock is another question entirely.
From what I gather of the backstory, he was scavenging the tools and parts from another abandoned ship, where it was safe to take off the helmet. He just needed to keep the it on for transit.
