The different parts are knit with approximately 2/3 fine merino wool and 1/3 synthetic material (polyester/polyamide). This is the optimal balance of fibers; it takes advantage both of all the unique properties of the wool, as well as of the durability of synthetics.

All parts come out like finished tubes. The great advantage of this is that the finished garments have a minimum number of seams, which allows for better body conformity and comfort, and eliminates excessive rubbing from bulky seams.
