I've been wearing the Ice Halo®, generously loaned me for review by the company, for a week. I've been wearing it in all my classes, and did a brief moves practice with it.
I am sold. It's moderately distracting when you first step on the ice, but no more than is a new costume with fussy bits, and I think because the one I've been wearing is fur, that's what I'm seeing. After about 5 minutes you forget it's there. Lots of compliments, because, well, it's very attractive. People would tell me "love your hat" and I would get to say "it's actually a helmet!" Many oohs and aahs. It's a little warm, but I wore it as long as 4 hours at a stretch, and it would just get moderately sweaty; not to the point of distraction or discomfort. This might be different for an extended high-level practice; I would suggest that the company investigate developing a "competitors" version with better moisture wicking.
One of the best things about it is that even if it shifts (which it never did), it's a ring, so it doesn't affect vision no matter what part is forward, unlike a full helmet.
I tested it on as many different types of skaters as I could- "baby" competitors, LTS class and LTS privates, high level multiple rotation jumpers, adults, and coaches.
SF (7-years old, FS3 class) Loved it. Mom loved it. Skated an entire lesson, doing all warmups, moves, jumps and spins. Stayed in place, looked adorable. Class coach thought it was a hat, or possibly is too self-absorbed to actually notice stuff like this. Her private lesson coach was receptive.
SBM (6 years old, Gamma private) Also loved it, and, again, mother also loved it. This is a child who can be fussy and difficult, but she put it on and forgot it was there. It did not shift for the entire lesson. I'm her private coach, so I'm on board. If it comes in turquoise, that's a sale.
Coach Fashionista: gave it 3 seconds, for a 7 year old child in FS2. Not, "let's go around one time and then see", not "hey mom, what's the deal?" Just a completely closed mind. This is going to be the biggest hurdle for this company. I think a coach this closed-minded about it can have a huge effect-even if the parents are adamant about a child wearing head gear (even such innocuous and fashionable head gear as this), the parent is going to lose, because a child will not go against a coach on this. Further, once a coach has made such a fuss about it (the mother described her reaction as "vehement") it's over-that child will never wear safety equipment. I feel bad that the kid lost face over this.
Adult free style class: very resistant, despite the fact that one of them is the mother of a student and was fine with testing it on the child, and that I know this is a group of skaters who really trust me. But they had lots of reasons why it could not even be tested-- sloping forehead, no one else wears it, I don't like fake fur, it's hot, I'll look silly (this after complimenting me on it, so either I actually look silly, or they were just making noise).
SR (very skittish adult, class) Would not even try it, despite the fact that she is clearly terrified of falling. First she complained that it would mess up her hair (the lesson is at 8:30 at night--what, she's going clubbing after this?). Then she decided it would be distracting (mind you she hadn't put it on her head). Unfortunately, the adults were universally the most resistant to it, even though they are the group who would benefit most, as I would venture that far the majority of head injuries I have observed have been adults.
Giordano and Davis (2010 US National Juvenile Ice Dance Champions): After an initial period of distraction, just fine. As I suspected, they felt it was hot, which might be mitigated by using the microfleece. Angel felt she could not do a layback with it on, it didn't feel secure, so this would be a definite issue for a competitive lady. They liked the idea of using these just when bringing new lifts onto the ice.
GJ (5 years old, Delta private, that's her in the picture) 'nuff said. All the 4- and 5-year olds did this. Every. Single. One. Get a skateboard helmet for the really little ones. (NOT a bike helmet--you want a helmet that fits close to the head, with good peripheral visibility and no points, which can force the neck to snap forward.)
Nora (professional skater, my daughter) Like all the high level skaters, she thought it was fine, but couldn't imagine ever wearing it. She ran through spins, jumps and moves and had no problems with anything, including the layback, probably because she was wearing it a little lower on the back of her head. She liked the warmth.
Chelsea (Senior ladies competitor) ditto Nora. All the high skaters who tried it claimed that high level skaters don't need safety equipment, while then proceeding to tell me all the awful injuries they have either witnessed or experienced. Sigh.
Manol (Bulgarian Junior Men's Champion) Like all the boys, he immediately "tested" it, by diving full speed at the ice and banging his head. No apparent effect, but with Manol, a head injury might just look like business as usual.
Stitch (St. Lidwina's kid) liked it, but Coach apparently had an apoplexy over it. He immediately started banging his head against the boards (he's short) "to see if it works."
The Noisyboys really liked it, but were extremely distracted by it, not because it was innately distracting, but because they are very distractable (this could be a general problem with boys and some of the crazier girls; the novelty of it was the main attraction). They also had a predictable boy reaction--punching each other in the head, yes "to see if it works." On the whole, however, their verdict was "yes." They wanted a better fit, but of course I had limited options for them.
Currently, these seem best for recreational skaters, who unfortunately are the least likely to suffer head bangs, at least on a per capita basis. The company would do well do develop lines for rental facilities and ones that specifically address the needs of competitive skaters. For rentals there needs to be a way to overcome the no-hat-sharing problem (because of epidemic head lice in some parts of the continent), especially since these are primarily cloth. Perhaps removable, replaceable (or washable) liners or covers (that's an on-going revenue source too!), and/or a plastic fashion side?
The other difficult hurdle is the coaches. ALL of the older and most of the competitive coaches were not fans, ranging from skeptical to scoffing to actively hostile. The Russians all hated it, and I caught at least one making fun of me. For something like this to catch on, I think the clubs and federations (SkateCanada and USFS) would have to make it required equipment, starting at the lower levels. Nearly every youth sport that you can think of requires safety equipment, in particular head protection, but somehow in figure skating it's anathema (not "pretty " I guess).
So here's the tl;dr (too long, didn't read)--it's a great product. I think it should be required equipment, especially for adult beginners. Buy it.
At this writing, I have not received any remuneration, products for personal use, or promises from Ice Halo.
