Angriecow is probably right on those two helmets, I'm not up on this years stuff, but in general the the whole ponytail port thing is bogus. A bone they toss us to appear woman freindly. Men with ponytails just put on a helmet and ride- women neurose about it. You need to get the helmet that fits and protects the braincase- you'll have sweaty helmet hair after regardless of where the ponytail sits. I promise you don't want to smack your head in anything less than an exquisitly fitted helmet. I went over the bars with a fashion statement on my head and got a nasty concussion, whiplash, and ten days in bed. Next year, I went over and landed on my skull on a steel railroad track in a Bell Pheonix (heh heh!) and walked away swearing like a sailor. See the difference? I got a big black eye and people kept giving me cards for the battered womens shelter, but I was out and about and just sort of bruised up.
Screw the ponytail port. Get the helmet that protects your brain.
