Sizing Guide
Your sleeve size is the most important measurement. The proper sleeve fit is vital to eliminate bounce on your run, so start with the arm guide for your tee, then check chest, waist and length in the size guide.
Arm guides
Women’s arm guide
Where to measure: sleeve length and cuff circumference.

What the markers mean
- S – Shoulder bone point. The top outer edge of your shoulder, where the sleeve seam sits.
- B – Bottom edge of the sleeve. Your size’s sleeve length runs from S to B.
- C – Measuring line. 0.5 in (1.3 cm) above B, inside the cuff. Wrap your tape around your arm here.
How to take it
- Stand relaxed with your arm at your side.
- Find the point of your shoulder bone (S), then measure straight down the outside of your arm to the S to C distance for your size in the table below. Mark that spot.
- Wrap the tape around your arm at that mark. Keep it level and snug, without squeezing.
- Compare the result with Sleeve circumference for your size in the table below.
- Always opt for a smaller sleeve circumference than your measurement. The elastane cuff allows for stretch to fit your arm – The snug fit of the elastane cuff eliminates bounce.
Where to measure from your shoulder bone

|---|---|---|---|---|---|
| S to B – Sleeve length (in) | 9.75" | 10" | 10.25" | 10.5" | 10.75" |

How to choose your size
YOUR SLEEVE SIZE IS THE MOST IMPORTANT MEASUREMENT.
The proper sleeve fit is vital to eliminate bounce on your run.
- Sleeve width is measured with the sleeve laid flat, across the cuff from one end to the other (think of the diameter of a circle).
- Sleeve circumference is measured on the inside of the sleeve cuff and equates to the circumference of your arm.
- Where to measure your arm for cuff circumference: from the point of your shoulder bone, measure down your size’s sleeve length less 0.5 in (1.3 cm), then measure around your arm at that spot.
- Measure down: XS 9.25" (23.5 cm) | S 9.5" (24.1 cm) | M 9.75" (24.8 cm) | L 10" (25.4 cm) | XL 10.25" (26.0 cm)
Measure a favorite tee across the chest and waist, then compare with the chart above. All widths are measured across one side of the tee, not all the way around.

Still between sizes?
If your sleeve feels too long or not snug enough around your arm, try flipping the elastane cuff up and under the sleeve. This shortens the sleeve and puts the cuff around the thickest part of your bicep for maximum security. Still not right? See our Returns & Exchanges policy or email contact@pockitapparel.com.
