Set fit: Use your largest measurement (chest or waist). Example: chest = L, waist = M → pick L.
Fit intent: Close to body for efficient heating, not tight.
Layering: If you’ll wear thicker mid-layers over the top, size up.
Chest (top): Measure under arms around the fullest part, tape level.
Waist (bottoms): Measure at your natural waist (above hips) with a relaxed posture. Hip: around the fullest part.
