Bud should be recieveing the Tree Stuff Protos today. My review is a group review from our crew, combined thoughts.
The Good
The suspension system is nice, a little more comfortable than the Kask. There are a lot of adjustments to it, so it should be great for all shapes and sizes of noggins. The honeycomb cushion is nice too. The ear muffs are much better than any other ear protection I have worn. It feels like they suction cup around your ears. The stow ability is a nice feature.
The Blah
For almost double the cost of the Kask, I expected to be wowed. My first impression when picking up the helmet was that it felt like I was picking up a flimsy kids toy helmet. The tightening system is nice, but if you are start the day wearing a winter hat and want to take it off if you warm up, you have to take the helmet off and readjust. Then you have to adjust the chin strap. Turning a dial on the back of the helmet is easier. Another issue, another winter issue I should say, is that the mesh face shield clogs up with ice as the vapor of your breath passes through. Visibility sucked. This only happened on the coldest of days, but I need a helmet that works throughout the entire year. My favorite part about the Kask visor is that it never fogs.
From an economic standpoint I think the price is absurd. For the price this product should be miles ahead of other products, and it is not. I honestly wouldn't buy this helmet if it were cheaper than the Kask. I think you would get more for your money to buy a Petzl or a Kask helmet and use the extra money to buy good chainsaw pants. I applaud Pfanner for trying to pave new paths and their innovation, hell I like pfanner and own a lot of their stuff, but this helmet isn't all that and a bag of chips like I expected it to be.
