Pros: micro-adjustable mount
Cons: heavy, hot, uncomfortable

The Giro Phase Bike Helmet is sold as a Mountain Bike, Commuter or Touring helmet, though removing the snap-off sun visor makes it suitable for limited use by road cyclists. It’s a fairly basic helmet found at the low end of the helmet price scale. It mounts with a standard flat braided chinstrap and a floating nylon headband. At the forehead, that headband has a slightly adjustable foam strip with absorbent facing. Other thin strips of padding are provided at the crown. The headband is adjustable one-handed with the Giro “Acu-Dial” feature, a knob at the back of your head that you can twist to loosen or tighten the headband. The helmet made of expanded polystyrene covered with polycarbonate. Mine is black and gray, though the Phase is available in other colors and patterns. The suspension system, straps, and buckles are black.

Giro doesn’t state a weight, but online research suggests it weighs 323 grams, or about 10 ounces, in the medium size. Road helmets like the company’s Atmos model weigh about three-quarters as much. The stated weight seems low to me, though, since the is one of the heaviest helmets I’ve worn in about three decades of skid lids. Giro claims there are 27 ventilation holes which, theoretically, means it’s well-ventilated. In reality, though, it's so hot that I‘d rather wear my old Giro Torrent, which has just 18 vent holes.

The Phase is heavy and hot, and its mounting system is bulky and clunky. The inverted V the straps make around the ears is too narrow. I do rather like the micro-adjustment capability of the suspension system: it makes it easier to adjust for a balaclava or skullcap when it’s cool, as opposed to a headband when it’s warm. This is no big deal, though, since the system is on all Giro helmets, and there are similar mounting systems on my Garneau helmets and my wife’s Lazer. If you ask me, unless your riding is basically short trips on the greenbelt of your suburbs or the occasional spin around the block, you can do better than the Giro Phase. Look for something cooler, more comfortable, and lighter.
