Fast Track Running Jacket - Black

We find Sweaty Betty to be true to size but if your measurements are in between those listed in the size chart, pick the next size up. For high impact activities like HIIT however, we suggest sizing down to ensure full support. Not sure how to measure?

• Chest: Measure around the fullest part of your chest, keeping tape firmly under your armpits and around your shoulder blades.

Not sure which size to choose?
