  1. Old post, I know but I saw some nice looking helmets the other day.
    These were snow boarding helmets...great for the coming cold. They had
    ear flaps that seemed pretty warm and were extremely comfy. They also
    had one that looked like a camoflauged war helmet. This was at [censored]
    Sporting Goods. They ranged from $20 to $100 depending on your taste
    and wallet thickness.

  2. Skate-style helmets are designed for multiple, lower-speed impacts. Bike
    helmets as lighter weight and much more ventilated, but are designed to
    absorb one (ONE) high-speed crash. That's not to say a bike helmet
    won't last for a while, but it is designed to be as protective as
    possible for one serious crash. Personally, I use a bike helmet (a Bell
    Influx) for all my riding, (mostly MUni). I haven't ever fallen on my
    face hard enough to need stiches, so i'm gonna put off getting a full
    face helmet for as long as possible. Just having something on your head
    is better than nothing....

    I don't actually know how often this generalization applies.
    Certifications from various organizations give some insight, though:
    Some standards for skate helments (CPSC, Snell) are based on bicycle
    helmet standards with additional requirements. ASTM F1492, on the
    other hand, tests for multiple, smaller, impacts. In some cases,
    "skate-style" helmets are only certified to bicycle helmet standards.

    That said, hard shell helmets are obviously more durable in case they
    hit a sharp edge or in the event of minor impacts. Skate helmets
    cover and protect more of your head. All helmets should be replaced
    after sustaining a hard crash.

  4. Now that you bring this up, something just dawned on me... Equestrian
    riding helmets would probably be a good match for unicycling since the
    falls would be similar (though from further up and a faster velocity on
    a horse). Might have to look into this (right now I just ride with a
    normal bicycling helmet).

  5. Bike hemets are pretty much useless for anything besides road biking.
    The main way you're gonna wack your head while unicycling is when the
    uni flies in front or behind you. Regular bike helmets are useless for
    both face plants and impacts to the back of the head, as they are only
    intended for sideways falls. A skate/BMX helmet will do a good job
    preventing concussions to backward and sideways falls.

    When you fall forward, there's more of a risk of breaking a wrist than
    hitting your head anyways.

    This is nonsense. First, plenty of bicycle accidents involve the
    rider flying over the handlebars (resulting in a forward impact) or
    being hit by motorists (which can cause a rearward impact). Second,
    the standards do not show bias regarding the direction of impact,
    requiring helmets to withstand impacts anywhere "on or above the test
    line" [CPSC standard, 16 CFR 1203, http://www.helmets.org/cpscstd.htm]
    [Snell B95 standard, http://www.smf.org/standards/b/b95std.html].
    I'll admit I haven't read the ASTM standard, or the ANSI which it
    replaced, because they are not frrely available and have been
    "sidelined by CPSC" [www.helmets.org].

    Out of interest, do you actually have any evidence for that assertion?

    He did say faceplant, not frontal impact. A faceplant suggests that the
    rider lands on their jaw or face before their head hits the ground.
    While no doubt the helmet may be able to help in protecting the head
    itself, there is no way it can stop broken jaw, teeth or cheekbones.
    While i agree that cotrary to what he said helmets can protect your
    head in frontal and rear impact, he nevertheless highlights a major
    failing in open face helmets, the lack of protection of the face. In
    the words of the label on almost every safety item I own, "This item
    can only protect the part of the body that it covers"

  9. I use a helmet designed for inline-skaters. is is the "skate style" so
    it protects the back of my head and my forehead much better than a
    bike-style helmet. it doesnt use polystyrene so it will last more than
    1 impact, unlike bike helmets which are designed to crack and shatter.
    the foam is more like a reasonably high density foam-rubber, which hugs
    my head tight. i can almost bend over with it undone and not have it
    fall off. unfortunately due to the nature of the foam it gets
    particularly hot and sweaty.

  11. Know what? I was wrong as hell about the rear impact. Ignore that.

  13. I use a Giro Xen helmet for MUni, They cover much more of the back of
    the head. Giro calls it "skate shaped with bicycle type construction."

    Bike helmets are not designed to shatter. They absorb impact the same
    way your skate helmet does: by compressing the foam. Cracking in a
    hard crash can happen. Your skate helmet may actually be designed for
    multiple, minor impacts (at least one test requires a small impact and
    a large one on the same helmet), though most are only certified to
    bike helmet standards.

    I don't know how your skate helmet provides better forehead coverage
    since skate helmets meet the same peripheral visions requirements as
    bike helmets. It might be a matter of not fitting the bike helmet
    properly. Skate helmets do cover the back of the head better,
    covering an additional 7% of the headform (per the Snell standard).
