It would be nice to know something about the actual product. Aside from being in a different language, the website tells us nothing about the garments.
Chamois make/model? Fabric weight and elastane content? Etc.
Not having anything else to go by my guess would be that it is another overpriced boutique brand lacking budget for actual research and development. Almost invariably their garments are made from inexpensive off-the-shelf patterns where poor fit on the bike is made up for by using highly stretchy, hydrophilic high-elastane content fabrics.
Seems to be only for women anyway.
