I don't chime in very often, but since the OP was mentioning multi day touring, I can say I'm incredibly impressed with the helmet I got at the April bike show, a Scorpion EXO-R2000. I had a Shoei TZ-R for many years that was comfortable - for me - out of the box, and I was having a hard time finding anything more affordable that was just as much a perfect fit. The TZ-R was easy to fog up and needed to be cracked open to air out in the rain, other wise a very good choice that pretty much spoiled me.
The EXO-R2000 features I like when it comes to 12 hour plus days include the amount of fresh air, the large eye port and the 2 fog resistant shields it comes with (tinted and clear). On my Cape Breton trip, I rode one end of New Brunswick to the other in constant heavy rain in August and no fogging, no leaks, no chilly spots.
In general, high quality finish and materials, composite shell, sweet bags for helmet and for shield, accepts my Sena base clamp mount.
The vendor was Speedworx. They are in Markham. Last April at the show this was under $400, tax in. You've got all off season to wait out for a good deal for whatever lid you decide on.
