Here's what other sites are saying:
Descend with power and control then skin back up again for more of the same on the BackUp Ski from K2. Able to take on any snow condition, these guys excel whether you're dropping down in refrozen conditions or skinning in hard bony stuff. You find yourself making laps at the resort, tele style, since you have edgehold from the metal & lightweight wood core and camber underfoot.

The 2010-11 K2 BackUp is the ideal spring-ski mountaineering tool, that s equally happy as a resort telemark ski. Two sheets of metal with an ultra-lightweight wood core provide exceptional edge-hold and a damp, supple feel not found in skis this light. Its 82 mm waist is narrow enough to excel whether descending frozen corn or skinning in hard, bony conditions, but wide enough to handle variable snow with ease and predictability.
