I got the microknit hoody in Medium and its huge. Much bigger than my Large Level 1 10 year jiberish was. As for the material and feel of it, its really comfortable, and nice and light. However, the material is almost too light, you can basically see through it, and in any type of wind/cold weather its not warm enough. Because of this, its not really that functionable but it looks pretty dope.
my micro knit did not smell like crap like some people's did. It is definitely a little bigger because of the stretchy fabric and it is thin, its a summer/spring hoodie so dont expect it to keep you warm. All said, i like mine. but im just scared of ruining it because it would probably rip easy, so i treat it like my baby
