Please measure yourself and use these charts to choose the right size. 

These measurements are for a standard comfortable fit, if you would like a looser fit please choose one size up from our recommendations.


Use a flexible tape measure or a piece of string and a ruler. For the best fit, measure over undergarments that you plan to wear with your clothing. 

A: Chest

Lift your arms up and wrap a flexible tape measure around the highest part of your chest and shoulder blades. Drop arms to your sides (over the tape) to take the measurement. It should be under your arms. 

Shirtbox chest measurements are all the way around your body, not just across the front of your chest. 

B: Body Length

Use a flexible tape to measure from the top of the shoulder down your body to the point where you want your garment to end.   



Have no fear, you can return your product within 30 days for a refund or exchange.

Really high quality Hoodie that is well made and warm (more suited to winter though) good sizing and manufactured to a higher than expected standard, print quality is very good, if I was asked “would you buy it again?” Then my answer would definitely be “YES”
