I get to try quite a few flying helmets for work, most of the non 'household names' and some that are, are absolute garbage. Comfotable garbage but still... I can't recommend many but I would say that despite awful lead times and sometimes suspect build quality Alpha Eagles/900's are pretty good. Absolutely avoid anything with gimicky chinstraps and air vents, or if the padding looks like it could have been taken from a motorcycle helmet..you'll end up with something with less crash protection than a 1970s skateboard helmet. Also, don't go chucking dodgy fixed wing ANR headset mods into safety certified helmets, unless these helmets have been impact tested to relevant standards with the modification installed, asking for trouble..
