Comfortable and casual enough for daily wear but still looks like you put thought into your look
Color: Grey Heather, Size: 3X-Large
Got this for my husband and was so pleased with the quality and fit. He wears it on top of his tee shirt and says it's one of the most comfortable hoodie he's worn. It's not too thick, but very warm. Great value as he wears it daily. Love the casual style while still looking put together.

Super stretchy and very silky feeling. It’s the same look at the lulu hoodie with similar material, but it’s different fabric. Very stretchy very silky
