I still use the husky classic, probably 1 of the last pro users to just a classic.
Got my last 1 for 25 quid.
Comfy enough to wear all day, as I do but I thi k there are better helmets out there now.
Never really liked the Stihl 1s as ear muffs on 2 wires.
As someone said u can get new earmuffs and stuff for husky helmets.
I think officially it's 5 years from manufacture, ( or after a severe knock on it ) no matter when u bought it, but that really only matters on commercial sites.
Only have been checked when cutting on railways.
Must admit I wear older helmets than that, only got a new 1 recently as left helmet/saws up wood and got sent to a new urgent the job next day, but still use the old 1 too
Best practice not to store in direct sunlight, think some now have UV stickers on them and u have to replace when they change colour
If it's only for firewood so very little chance of something landing on ur head I wouldn't bother the age, althou by the time u replace muffs etc u might be not that far off new price.
But it will protect against kick back to some extent, althou I'd prefer to rely on good technique/training and body position 1st.
If ur saw is so out off control it struck ur helmet it could end up anywhere ur helmet might not do much good
A lot of pro users now are onto fancy blnged out ARB helmets now, protos, about 200 quid thou meant to be comfy but any company that makes a green coloured forestry helmet is bonkers.
Just so natural for decades to glance up to look for ur nearest orange helmets when felling
Meant to be comfy and a few idiots have fancy mesh visors, flags, skulls etc
