I am literally right in between the medium and large on the giro advantage 2 and do not have a tri shop close by to try them out. Any ideas? Do they run a big or small or are they right on and I'm just out of luck and stuck with the helmet being too big or too small?

I can't speak for the Giro, but I was between a Med & Sm LG Rocket. I initially bought the Medium. I could tighten the size medium helmet so it fit snuggly. The shell was really wide around my ears - huge gap. All in all the medium was a comfortable fit. I tried on my buddies size small and it was a snug fit. The shell fit perfect. So I ordered a small. Problem was on a ride after about an hour I got a huge headache from the squeeze on my head. So make sure you give your head enough time to determine which size will work best.
How's the heat management in the Giro? The medium was a little too wide on my head (like an air scoop) and the small felt pretty snug. I could feel some of the heat retention as I wore the small around the bike shop, but I didn't get to try it on the road.

When i turned around at Hawi at Kona last year, my srm computer said it was 104, and i didn't think once that my head was hot. ymmv. ishi no ue ni san nen | Perseverance will win in the end. | Blog | @nebmot | Strava | Instagram |
I was in the situation you are, except with the SM & MD. The small felt tight around the ears and a little harder to put on, but the medium just seemed to have a lot bigger all around profile and didn't seem as aero. I went with the small a have had no regrets. Even though I had concerns that my ears would get uncomfortable over longer distances, the most uncomfortable I have been was while trying it on in the shop.
