I am very heat sensitive. It gets hot in the summer here. Show season is in the summer. I got an IRH because I "had" to have one to show AAA rated shows in. I HATED it. I wasnt even going to try a charles owen because they have no vents. I also have a long oval head, neither fit properly. I found the only helmet in my life that ever fit me again (my friends dog completely ingested my first one) on ebay
because tipperary quit making them *something about technology and standards bla bla bla* and I bought it. I love the origional tipperary. It is truly THE ONLY helmet that has ever fit me correctly... that was, until, I found a GPA speed air at a local tack store... the only reason I looked at it was because it was less than 1/4 of the normal price. It was a demo and it just so happened to be custom... a 7 1/8 extra long oval... I bought it and I am saving it to show in, though I do truly love it and I would recomend it to anyone that finds a deal or has the money to buy one! I would highly suggest really searching for one if you don't haave the money to go out and buy one. They are well worth the wait and should last you a long time and not only that but they keep MUCH better than the IRH and charles ownen- they are easier to keep clean and look better and are sturdier!
