M51 Fishtail Parka | Men's Vintage Hooded Military Jacket
The Original Fishtail Parka Shape.
Men's vintage M51-style fishtail parka in army green.
A loose military shell with a big hood and the split fishtail hem at the back. Throw it over a knit or hoodie and it handles most of a British autumn.
The Story Behind It
The M51 fishtail parka was designed for the US Army in 1951, with a split tail at the back that could be tied around the legs for warmth. Surplus parkas were taken up by British mods in the 1960s and it has been a street classic ever since. Japanese Amekaji style keeps it close to the original military shape.

Men's M51 Fishtail Parka FAQs
What is a fishtail parka?
A fishtail parka is a long military coat with a split tail at the back, first issued to the US Army as the M51. This is a men's vintage version in army green.
Is it warm enough for winter?
It is a shell weight. The loose cut leaves plenty of room for a hoodie or thick knit underneath on cold days.
What fit should I order?
It is cut loose. Take your normal size, or one size down for a less roomy fit, and check the chest measurement above. Sizes run S to 2XL.
Does it go with the M65?
Yes. It shares the army green and military details of our M65 Field Jacket.
