## Three questions to Vitus Schweizer, Head of R&D at Colltex ##
**What do you consider to be the greatest challenge of this project?**
Colltex Drybase is the next step in developing our future ski skins. With this «positive change of the product», we had to pay great attention to avoid any negative impact on the already optimized and good properties of the ski skins.
**Did the changeover to Colltex Drybase work out for volume production?**
The step from the sample phase to our large production machines is an exciting stage of development and often comes with surprises. With Colltex Drybase, we were able to successfully transfer the positive and encouraging results of the sampling phase to our large-scale production.
**The advantages of Colltex Drybase include greatly reduced water absorption, an optimum chemical bonding to the adhesive and increased strength. What do you consider to be the most obvious advantage?**
The low water absorption is certainly what most ski tourers hoped for. For me, it is equally exciting that the Colltex Drybase technology allows us to adjust the torsional strength and flexibility of the entire ski skin. Also highly interesting is the slight cushioning effect of the coating. The skin compensates even the smallest irregularities which, in turn, has a positive effect on gliding and climbing properties.
