Lightweight Hoodie
Color: Black Grey Heather, Size: XX-Large
This is my lightweight hoodie. It runs a bit small. I'm typically an XL, but I like my hoodies bigger, so I got a 2XL, but the fit is more of that of an XL. So it does appear to run small.
The material is nice, but warm, which makes sense since it's polyester and spandex, not very breathable. I'm also worried about how it holds up over time with those materials, from my experience it will get those little fuzz balls, ruining the look, but time will tell on that one.

Great fit, quality, design, and value. It lightweight but also has a thickness so I can wear it on cool mornings in the Northeast. I highly recommend!
