The official Easy Trolley is only allowed when you travel on duty e.g for recurrent or another base. For the normal day you have a crewbag which I do not prefer...I'm carrying too much stuff with me ( bloody senior stuff..*lol*) you only need a small night stop kit...underwear and cosmetics and that fits into the new bag.
When I did the training I was lucky because I received my uniform on the last day...so I spent the whole training in my own clothes. Very comfortable becuase we had a very hot 4 weeks in LTN ( over 30°C ). And our uniform isn't that nice when it's hot..*gg*
