Traditional lederhosen are hand made of tanned deer leather which makes the pants soft and light but very tearproof. As those leather pants are very valuable and can last a lifetime some Bavarian people even bequeath their lederhosen to the next generation. Some variations of modern lederhosen are made of heavier, lower quality leather, or imitations like velour leather which make them much cheaper but less durable. All variations are usually equipped with two side pockets, one hip pocket, one knife pocket, and a codpiece (drop front). For an octoberfest costume people combine lederhosen with Haverlschuhe, stockings and a classic white or checked shirt. 
The British games manufacturer Jaques of London were commissioned by MI9 to produce a variety of games (from board games to sports) which contained numerous escape and evasion devices. These included travel and full sized chess sets, with contraband inside the wooden boards, the boxes or the chess pieces themselves, table tennis, tennis, badminton racquets containing money, maps and miniature compasses, dart boards filled with escape devices and tools, shove halfpenny boards, hollowed and filled with escape aids, and larger boxed games containing even more contraband. It was not until X-Ray machines were deployed at German POW  camps, that the German authorities began to capture significant amounts of escape material.
