T-Shirt Size Guides

The Mountain® t-shirts are US sized and may be slightly larger than you're used to. Please check the measurements carefully before purchasing. 

* Measurements are width and length of a shirt.  Example: You need a shirt that will fit a 40 inch chest.  A medium shows a chest width of 19-21 inches. Double this measurement which will give the circumference of the chest.  19 x 2 = 38 inches  21 x 2 = 42 inches.  Medium will fit someone with a chest between 38 - 42 inches.

Scroll to the bottom for additional help with how to measure.

Measurements can be taken two ways 1) use a tape measure around the chest to get the chest size in inches. 2) take your favourite fitting t-shirt and lay it out flat. Take a tape measure and measure armpit to armpit. Next double that number and you will have the chest measurement you need to order. For example: armpit to armpit measures 20 inches you will need a 40 inch chest (Medium).  For the length measure from the shoulder to the bottom
