I had another known brand but it was a bad color choice and had very shallow pockets and kind of cheaply made.  This is a better quality hoodie and I like the pockets, color choice of teal and should last a very long time unlike my other one. I wasn't sure what size to get, but went ahead and ordered the medium and it fit great and even if it shrinks when I have to wash it the first time, I'm sure it will still be the best size choice.  I am 5'7" and about 140 pounds and usually wear a size 8 just in case you need a size reference.
