My new favorite hoodie!
Size: XX-Large, Color: Charcoal Heather
I love this, this is my new go-to hoodie! It's very soft and breathable, it's roomy and comfortable, and it's not too heavy. I've washed it a few times and it's held up well. For the price, you really can't go wrong. I'll probably end up buying a couple more colors.

Sleeves are too short
Size: Large, Color: Black
Good quality about as thick as heavy t shirt. The only issue is the sleeves are a tad short which is a bit disappointing. Not sure I will buy this again. I’m 5-7 175 and ordered a large and it fits well. Just a smidge oversized like I prefer.

Lightweight and comfortable
Size: X-Large, Color: Black
Lightweight yet warm. Bought an XL for my husband who is 6’ 2”, weighs about 180 lbs, and has long arms. Fits a bit loose but not too big but have to size up so the length in the arms fit better. He runs warm so dislikes anything that makes him hot, so this material was great. Did not discolor or shrink in the wash, which was a bonus.

Hubby is quite happy with this hoodie
Size: X-Large, Color: Navy
We live in warmer climes, so DH wanted a pullover hoodie that was more like t-shirt material. This is fantastic- it's like a well-made t-shirt - like a thicker, better quality tee. He loves it. The fit was just right. There was no fading in the wash - I always wash clothes in cold water though, so ymmv. He was happy with the color I chose. When cool weather rolls around again, I will add some other colors to his collection - perfect lightweight pullover for him.
