Size & Fit Guide

How to measure

CHEST: Place tape measure under your arms at the fullest part of your chest, wrap around your body until your fingers meet and mark the measurement.

WAIST: Measure around your natural waistline-right above your hips. Be careful not to squeeze too tight to allow a little give.

HIPS: With your feet together, measure around the fullest part of your hips to ensure you’ll have enough room to move comfortably.

Q&A(4)

What size is a small? For what ages approximately?

JC12455

3 years ago

We apologize, as we do not have a designated age range for sizes, since size may vary depending upon individual measurements. A YSM is ideal for waist sizes of approximately 24 - 25 inches, hip sizes of 27 - 28 inches, and heights of 50.5 - 53 inches. Please see the link below! https://www.underarmour.ca/en-ca/t/sizechart-boys-bottoms.html

How long are these shorts? My 13 year old is very slim but is 5”8 so he is kind of between sizes.
