Такой же вопрос я задавала болгарам и вот что они мне ответили:

Don't worry, for sure you will find the right equipment for your needs.
They offer mostly Salomon equipment (2-3 years old models). But you can hire equipment from other brands as well.
As I remember the ski which they offer are Salomon Verse and for a bit higher price you can hire V.I.P set where the skis are Salomon Eqipe.
