Fit tip Altura jerseys and jackets are cut for a regular riding fit; if you are between sizes or plan to layer underneath, choose the larger size.
How to measure
Measure your chest around the fullest part with the tape high under the arms and level across your back. Measure your waist at the narrowest point, which you can find by bending to one side, and your hips around the fullest part with your feet together. These are body measurements, not garment measurements, so compare them directly with the table.
