The Professional Safety Kit with Comfo Respirator is available in 3 sizes.
Per the manufacturer, if there is any doubt about whether a certain size will fit you, you should always elect to go to the next size up. It is better that the Coveralls be a bit loose than too snug.

XLARGE will fit up to:
Height of 6'2"
Weight of 220 lbs
XXL will fit up to:
