Strong and lightweight, the Giro Sheer ($160; giro.com) is a great choice for the off-piste Rocky Mountain steeps. With two sizes (52-55.5 cm and 55.5-59 cm) to accommodate any head, the matte Sheer, which has a molded visor and a feminine henna-like design around the base, has an easy-to-operate (even with gloves) dial system for a fine-tuned fit. It also has 12 vents to regulate airflow on those sweaty hikes, a stack vent to keep your goggles clear of fog and snow, and in-mold construction, which means that the outer shell is bonded to the inner expanded polystyrene liner making the helmet extra durable. If you want distractions on the long slog up the mountain, the Sheer is also compatible with Giro's TuneUps wireless system ($200), which allows you to answer your phone, listen to your music, and turn up the volume—all without taking off a glove.
Swedish company, POC, designed the unisex Backcountry Receptor ($250; pocsports.com) specifically for advanced skiers who like to expose themselves to the elements and avalanches. In addition to having a built-in RECCO avalanche reflector, which will aid rescuers in the event you're buried in the backcountry, it also uses a patented technology that allows the helmet and shell to rotate together to reduce the rotational forces on the brain upon impact—a smart innovation, especially for those who prefer to ski the trees.
