Side and rear coverage is the phrase that separates this helmet from everything else on this list. A chainsaw helmet is built to take something falling on the crown; the Protos is shaped to shrug off a hit from the side as well, which is where a limb swings when you're up in the tree and where ordinary hard-hat protection is thinnest.
The whole system runs off two fingers, which stops being a small thing the first time you're 40 feet up with gloves on. The ear muffs click out and swing back inside the shell so they don't snag on brush, the vents open and close for airflow, and the swept-back profile keeps your upward view clear when you're sizing up the next branch.
The adjustment is the learning curve. It's a fiddly system the first afternoon — plan a session with it on the ground rather than on the job — and after that we didn't touch it again. Every part is replaceable, including the muffs and the visor, which is what you want from a helmet that's meant to be worn every day.
For a climber or a full-time arborist, that's a fair trade for the coverage. For a homeowner cutting firewood twice a year, it's a lot of money for protection you're unlikely to need. And if you work to a US site requirement, confirm the European rating satisfies it before you spend — the hard-hat certification here is EN, not Z89.1.
Bottom line: The helmet we point climbers to: side and rear coverage, two-finger operation with gloves, and a fit that disappears once it's dialed.
