As a long time fan of my Ororo heated vest, and classic heated jacket, I was excited to get this heated fleece. It's perfect for those chilly days where the weather is cool enough for some added heat, but not requiring the layering that goes with wearing my vest under another coat or jacket, and not cold enough for my heavier classic heated jacket. This heated fleece hits that sweet spot in between. In and of itself, the fleece is soft, warm and comfortable. I wore it to a couple of baseball games lasting 2-3 hours each with the temps in the low 50's (maybe even dropping into the upper 40's), and I was completely comfortable throughout. I love the addition of vibration to the control button. That tactile feedback is perfect when turning it on or changing levels. It's not as obvious what level you're on with the button on the inside at the bottom hem and I did have to flip it back on itself to see what level it was on when I wanted to change it, but honestly I'm good with that trade off. Being able to discreetly reach down and under the bottom hem to turn it on is very easy and discreet. It's not that I've ever disliked the glowing control button on my chest, but with this on the inside no one sitting around me even knew it was a heated jacket, let alone that I had turned it on. There were 2 minor reasons I deducted a star and only gave it 4 instead of 5. The first is nit picky, and admittedly personal preference. I'd prefer the collar be easier to fold over and lay down. I know it's designed to integrate with the outer shell, and that's likely why it's more prone to stand higher so that it can be snapped in. The other reason is sizing. It seemed just a bit too long in the arms. I wear a large in everything for shirts, jackets and coats, in all brands (including Ororo). The arms on this fleece were just a touch too long and came down well past my wrist. The body of the jacket fit well enough that I didn't think it was the case that I needed a medium instead. But, with those two minor things in mind, I still like and look forward to wearing this jacket more on those cool days.
