These briefs come from a lingerie series by Zimmerli, which is body-hugging and sporty cut. It is created on circular knitting machines as superfine yard goods, which are then cut and precisely made up.

The Swiss fine knitwear manufacturer Zimmerli has always used machines built specifically for Zimmerli production. These machines process long-staple cotton. It is spun into a high-twist yarn (unusual for knitted fabrics) and mercerized twice (washed in sodium hydroxide solution), which prevents the finished garments from shrinking and gives the product a silky sheen and a smooth surface. In addition, Zimmerli underwear is elastic both lengthwise and crosswise, even without synthetic additives. Careful inspection of the seams, multiple ironing passes, and final finishing account for more than a quarter of the total production effort.
