How to Measure

Bust

Measure around the fullest part of your bust, keeping the tape level and snug but not tight. Arms should be relaxed at your sides.

Length

Measure from the top of your shoulder (where the shoulder seam would sit) straight down to the hem.

Sleeve

Measure from the center back of your neck, across the shoulder and down the arm to the wrist, with your arm slightly bent.

Size Selection Tips

  • This is a body measurement size chart — select your size based on your actual body measurements, not another garment.
  • This top is cut for a close, athletic cycling fit in stretch thermal fabric — it sits snug against the body. If you prefer a looser layering fit or plan to wear a base layer underneath, we recommend sizing up.
  • If your measurements fall between two sizes, we recommend choosing the larger size for a more comfortable fit.
  • All measurements are listed in inches. Allow ±1" tolerance due to manual measurement.
