ALPHAFEM Size Guide — Find Your Perfect Fit

Our riding jerseys are designed with an athletic fit for optimal aerodynamics and freedom of movement. We recommend ordering based on your chest measurement, not your usual T-shirt size.

How to Measure Yourself

• Chest: Measure around the fullest part of your chest, keeping the tape parallel to the ground
• Waist: Measure around your natural waist (narrowest part of your torso)
• Arm: Measure from the top of your shoulder to your wrist with arm slightly bent
• Use a soft measuring tape. Measure over light clothing or underwear only.

Fit Tips

• Between sizes? Size up — our jerseys are athletic fit and will stretch slightly with wear
• Full-bust riders: If your bust is more than 2" larger than your chest measurement, consider sizing up
• The jersey should feel snug but not tight. You should be able to raise both arms fully without the hem lifting above your waist.
