One word of advice.

As many have warned already, it is best to order your jacket one size larger than your t-shirt size.

i.e I wear a XL tee and ordered a XXL jacket.  I am broad-shouldered with a wide chest.  This jacket fit me nice zipped and unzipped.

(I previously had this same jacket as a XL and found the sleeves too short and the jacket was snug on me when zipped up.)

Order 1 size larger is the best advice I can give.  Perfect for mild weather and is the choice for Spring, Fall and chilly nights.

Great jacket !!!
