Pack dark clothes that dry quickly and either don't wrinkle or look good wrinkled.

Pick one or two colors. Dark clothes look less wrinkled.

Try synthetic fabrics:

• Nylon dries in minutes and weighs little.
• Seersucker looks good wrinkled.
• Coolmax dries quickly, won't wrinkle, and is cooler in summer and warmer in winter than cotton.

Test your clothes by hand-washing them at home. See how wrinkled they get, and how quickly they dry.
