I was looking for an auto darkening helmet too. I would ask the same question - what's the difference between the HF and Hobart helmets ? They are both made in China , have the same specs , etc. I get the same answer - It's youe eyes. So , I bought the Hobart from Tractor Supply for $ 100.00. It's black. I could have bought a camo or flame helmet for $ 20.00 more. I guess I trust Hobart more than HF.
