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(9)

What happens to these fleece pants if you use fabric softener? I use it in all my clothes and would prefer not to have to do special wash for these.

Dianna27

Typically, fabric softener is not advised for polyester, workout clothing, or clothing that wicks sweat/moisture, as it may alter the fabric and its properties over a period of time.

What size should boys 8-9 be? SM OR Med? FYI a size chart would be helpful.

This would vary depending upon personal measurements. We would recommend comparing your measurements to our Size & Fit Guide on the product page for the best size recommendation, or see below! https://www.underarmour.com/en-us/t/sizechart-boys-bottoms/
