What are Royal Marines starting basic triNing meant to take with them to lympstone? what underwear are they allowed to take? The kit list says “underwear must be dark in colour, of an appropriate fabric and design commensurate with use throughout Initial Training and suitable to withstand The rigours of the robust and demanding training environment. Boxer shorts and thongs are unsuitable for physical training.“ so what does that mean... *text deleted*. Does it mean he can pretty much take anything but thongs or boxers hahhah . Would a trunk style be okay to take or what?
