The Dynastar E-Pro 90 Open Skis is a wonderful all mountain ski for advanced women's skiers that is built the same way as the Men’s version, which is the Dynastar M-Prop 90. The main difference, it comes in smaller length sizes to accommodate lady rippers. Construction starts with a poplar wood core that runs the central spine of the ski, polyurethane or PU material basically surrounds that core as a frame. Since the ski lacks a full-metal laminate, it does need some type of construction to keep it damp and smooth, and this PU material works incredibly well. In addition to this PU and wood core, the skis also benefit from Dynastar's Rocket Frame Ti laminate. This partial metal layer is edge to edge underfoot, and extends and tapers to the middle towards the tip. This gives the ski a playful feel, better flotation, and smoother turn initiation while keeping the mid-part of the ski stable and strong. At 90-millimeters underfoot, the E-Pro 90 is in the “Goldilocks” zone for waist width for true all-mountain prowess. Even though the name indicates 90, the waist is actually an 89 at the 170-centimeter length, so even though it's a bit narrower than advertised, it still holds up to a variety of turn shapes, styles, snow conditions, and terrain. Advanced to expert women's skiers will fall in love with quiver of one Dynastar E-Pro 90 W Skis.
