The My No. 5 is similar in shape, construction, intended use and price to the No. 6, but with a narrower waist (71 mm) and even deeper sidecut for can't-miss carving on groomers. It's sold only as a system, with a 10-DIN Head Mya binding. It's a Sandwich Cap Construction (wood-core laminate layup, with shortened vertical sidewalls, for edge grip, topped by rounded cap-construction shoulders, for a touch of forgiveness). Head's Allride Rocker combines 80 percent camber for edge and rebound with 20 percent tip rocker for soft-snow flotation and shock absorption. All Mya women's models feature Head's ERA 3.0 design philosophy. The "3.0" refers to the fundamental triad of radius (ie. sidecut), rebound (ie. flex), and rocker. Head designs all ERA skis so that these three fundamentals work in harmony, specifically adding more width at the tip so that the introduction of tip rocker doesn't compromise turn initiation.
