Prosecutors were opposed to allowing Mohammed to wear the camouflage gear, arguing it could undermine the courtroom proceedings.
Mohammed has said he is the mastermind behind the 2001 attacks, and the others are accused of providing logistical and financial support to the hijackers.
On Monday, Judge Col. James Pohl ruled that the defendants did not have to be present for the pre-trial hearings, and three defendants opted to skip Wednesday's proceedings. Mohammed showed up several hours late, according to reports.
The pre-trial hearings will last through the rest of the week. The trial for the defendants is not expected to begin for more than a year.
As for Mohammed’s camouflage vest, reporters attending the Guantánamo tribunal were immediately interested in its origins.
The Wall Street Journal reported the vest was from New York clothing company Rothco, an item described as a “vintage ranger vest” that retails for $52.49.
But the Herald found the better deal, reporting that the vest could be purchased for $39.99 in a Sears online catalog.
