As you have probably found in the past, no two brands fit alike. You may be a medium in a Burton Jacket, but need a Large in an Arc’teryx shell. Our sizing charts give you the information you need so you can select the right fit in the brand you want. Also remember, if you order it and it doesn’t fit the way you want, we offer a 100% satisfaction guarantee. Send it back and get something else that fits the way you want.
