Great hoodie
Size: 3X-Large, Color: Deep Red
This hoodie is super comfortable and soft, I love the variety of colors it comes in also. The quality is very high for the price and the zipper is easy to use with it not getting stuck every swipe up and down.

Really good value
Size: Large, Color: White
These are great quality. The fit seems true to size. Thick enough to keep you warm but not to thick. Zipper seems to be good quality metal zipper, fabric is soft and washed well. I purchased this to use it for tie dye.

Good Value with a Couple of Nitpicks
Size: X-Large, Color: Black
I purchased this hoodie as a lighter weight alternative to the ones I already own, and it works well for that purpose. The hoodie is comfortable and of a general quality commiserate with the price point.
The Nitpicks: The pockets are on the small side. Unless you’ve got huge mitts, your hands will fit. However, if you wish to carry items in your pockets, they may not be secure, particularly during vigorous activities. The hood is a little smaller than typical. I frequently walk while wearing old school headphones and have a slightly larger than average head and consequently the hood can be a bit tight. Not unusable but raising and lowering the hood in this scenario is usually a two-handed operation for me. Maybe not a problem for most, depending on use case and cranial size.
