CHOICE OF SIZES
The choice of size is very important and it depends on how you like to wear your jersey and bibs. All our patterns and fabrics are to wear tight. According to the measurements in the table, the cycling kits are a tight.
Measures that match, you reported that you can take any of the two sizes. The fabrics we use are very elastic and there should be no problems for the sizes. For example, a person who has 36 inches of bust may be a size S leaving him very tight. In the same way, a person with 35 or 36 inches bust could lead a M leaving you a little more loose.
If you doubt, take your measurements according to the diagrams and send them indicating how you like to wear your clothes (loose, tight, etc.) to email@example.com
