To find your correct shirt size, please find a running shirt that fits you well. Lay the shirt flat on a table and measure the width (of just one side) of the shirt from arm pit to arm pit.

If you have worn a shirt from The Trail Co. before then this is the size you should choose again. Please note: while we try our very hardest to ensure a perfectly fitting shirt, due to manufacturing tolerances there may be a slight difference in your shirt dimensions from those recorded in this table.
