TAD Gear stuff can be expensive, but it is very, very high quality.
This hoodie has Malden Mills fleece, which is the real McCoy -- it is much less likely to pill, much higher quality, and heavier than most other fleece. BTW, IIRC, Malden Mills burned several years ago, and had to be closed until it was rebuilt. Instead of laying off his workers, the mill owner took the hit on his own and kept them on the payroll. Sure, there were a few cuts and some had to go for lower pay, but who else would have done this or anything close to it? If this really is the same mill, I'd be willing to pay a bit extra just because of that. Plus, it's American-made. Very few gear makers use this fleece.
Back on topic, did you scroll down the page? You didn't notice the channel built in for headphones/cell phone headset? Did you see the cuff design that keeps your hands warm for real? The sleeve pockets are pretty well designed, too. All unique features. The other brands you mention have nice outer gear and good quality, but these features and material are why the TAD Gear hoodie costs more.
Yes, you can find less expensive hoodies (heck, isn't a $20 one good enough for most people?), but this one is pretty special, and, yes, pricey, but it is a specialty item. And since I need a fall jacket... hmmm.
