I all boils down to where you are and legally what is required if its for work, and for the everyday consumer, how much you figure your head, eyes, face, and ears are worth.
If being used commercially anywhere in Canada the helmet has to be CSA (Cdn Standards Authority) approved should you ever hope of making a claim. The Husqvarna pro forestry helmet is not CSA approved and cost more than the regular helmet from Husqvarna, CE and meeting the CSA specs means nothing, it needs that lil stamp on it. Just an FYI for our northern members.
Anything is better than nothing, when is -30c/-22F any brain buckect sucks, for working in the bush a ratchet style suspension in vital, and it should be tight, your helmet should never fall off your head while you are working.
For those with plastic/poly helmets and even suspensions, the material degrades in the sun after time, so replace them on a regular basis.
