SIZING TIP: The 4XL has a 64" relaxed chest measurement, and is 32"+ down the back.
LINER TIP: We have sold all our liners for the System. If you search online and find Reversible Liners for sale on the Web, they will be EXTREMELY SHORT - 28" long down the back. Feedback on them from customers was terrible. There were a few Polar Fleece Liners that were a better cut, but we are unaware of who may still have some.
However, this Outer System jacket is VERY POPULAR and a BEST SELLER!! GET SOME!
