Ask ten cyclists the best way to fold a business shirt, and you will get ten different answers. Ride On went undercover and discovered the technique for shirt folding used by the Royal Australian Air Force.
1. Lay the shirt face-down on the folding surface. Smooth out any wrinkles so the shirt is completely flat.
2. From the right side of the shirt, fold about one-third of the body in toward the centre of the shirt. The fold line starts at the centre of the shoulder and ends at the tail. You should see the back of your shirt with about one-third of the front folded to the back.
3. Neatly fold the sleeve forward, creating an angled fold at the shoulder. The sleeve should line up with the edge of the first body fold.
4. Fold the left side in the same manner.
5. Fold the shirt tail up several inches and then fold again, moving the bottom edge to just behind the collar of the shirt. Turn the entire shirt over. Ta-dah!
6. Many riders use the fold and roll technique; once folded, the shirt is rolled up to form a tube.
Shirt folding boards that help ensure a consistent fold can be purchased, or made out of stiff cardboard.
Some advise limiting the amount of friction between fabric layers to lessen the amount of creases. This can be done by layering the shirt between two big pieces of plastic, such as a dry-cleaning or garbage bag, and folding the shirt as normal, but with the plastic between the folds. This will prevent creases ‘sticking’ as the fabric is not rubbing against itself.
Spacious panniers or a big bag minimise crushing or you might also stash a few days’ worth of clothing at work on a non-riding day. Many people use a combination of options, depending on weather, storage and change facilities at their workplace.
