Choosing your jacket size is important but very simple. We have combined all our jackets into standard size ranges from XS to 6XL. Some sizes include a -T, -L or -S to denote the length of the item, being Tall, Long or Short. Simply pick the size shirt that you normally wear and the correct jackets will be displayed for you. If you have fit concerns for a specific brand please check out all our size charts for exact specs.
