Measure Your Chest: Use a measuring tape around the fullest part of your chest, keeping it horizontal and snug but not tight.
Consider Your Riding Gear: Measure while wearing a base layer or shirt you'd typically ride in–especially if you plan to layer underneath.
Allow for Mobility: A good fit should be snug but allow freedom of movement. Remember that armored jackets might feel stiffer at first.
Check Sizing per Brand: Always consult the brand's specific chart–fit can vary by style, cut, and country of origin.
