This is probably the closest you can get to looking like a badass samurai while wearing an everyday modern zipped hoodie.
 
If that doesn't make you want it, well... nothing will.
 
I think of it as confidence-building without slipping into all-out cosplay.  Features our own kamon (two small on the front, one larger on the back), in traditional Haori style placements. Tradition, updated for the street.
 
Well made, highest quality hoodie, with a sturdy metal zipper that will actually work.
 
Here are some more details.
 
270g/m2 (7.75 oz per sq yd). 50% cotton / 50% polyester, preshrunk preshrunk and ever-so-comfy. 
Air jet yarn (whooosh!), soft to wear, and doesn't pill up like a jerk.
Heavy duty YKK metal zip, nifty pouch pockets, perfect for shrunken, smoke bombs and kunai! No, actually, we didn't encourage that. Not in these times. You can warm your hands in there and stow some of your stuff.
Double stitching for strength and durability.
Sizes:XS, S, M, L, XL (have a measure against the chart to get the best fit, and don't forget, if you'll be wearing it over other stuff like your Winter battle Kosode, it's never a bad idea to size up a little).
