Hi Anton, the Session is Movement's do-it-all ski. They rail on hard snow and corn, and float reasonably well. I'd say both metrics are a step up from the Nanga, but the feel is not too far off, maybe a touch stiffer.
The precut skins are 100% mohair with standard tip loops and an adjustable tail clip, correct. They come with protective netting (cheat sheets) and a carry bag. The glue is among the most sticky in the business.
