I bought this in Nov 2012 on a lightning deal, never having heard of the brand. All of my other hoodies are relatively heavy sweatshirt material (all cotton) and have logos or sports teams on them, so I liked that this one appeared to be (a) plain and (b) lightweight.
It delivered on both. No logos anywhere on it, and the material is a cotton polyester blend that makes it pretty breathable. It's great for those times when I'm just a little bit chilly in a short-sleeved shirt but don't want to overheat in a jacket. The fabric is thin - if you hold it up to the light you can see through it slightly. My only complaints are with the hood, and they're minor - it's a bit too big, and its strings are way too long. One reviewer here said he took the string out - that might be what I end up doing too. Even though the hood is big, the thin material means it lays flat when I sit down, unlike my bulkier hooded sweatshirts.

As for the complaints in other reviews of strings hanging down everywhere and being poorly made - I'm not sure if those reviewers got a defective one, but mine has none of those issues. Stitching is just fine, and the only hanging threads are the intentionally frayed seams with a bit of fringe (less than half of one centimeter in length).

On sizing - I'm 5'10" and about 185lbs, and chose large, because it appeared slim-fitting. I wear 16.5" neck shirts with 34" sleeve length and don't like things too form-fitting. I like that this isn't a giant, baggy sweatshirt, but in size large the sleeves are a bit long. I considered exchanging for medium but I assume it will shrink a tiny bit over the first few washings. All in all, a good purchase, even though I suspect my body shape is between sizes for optimal fit.
