Sale: $79.00 - Retail: $180.00 f there is a little girl out there looking for a purple twin tip ski, this is her lucky day. The Head Frost One is modeled after the Head Sure One skis, but with a different graphic. This means the ski is great for beginners all the way up to advanced youth skiers, that either need a twin tip to ski backwards or to look like their older siblings with twin tips. This is a very light ski, so little muscles have a better chance of controlling them without getting too tired.
