SADDLE PAIN STOPS HERE
Kostüme makes the most comfortable bib shorts in the world.
But don't take our word for it. Ask Sarah Ruggins.
After being hospitalised by saddle sores on her LEJOGLE ride, Sarah wore our bib shorts for 6,000km across 9 countries in just 13 days - riding for up to 22.5 hours a day. The result?
2 world records. Zero saddle sores.
With multiple 10/10 reviews and Editor's Choice awards, plus 5* customer testimonials from ultra cyclists in 41 countries, we don't promise performance. We prove it.
Our bib shorts are only possible thanks to our unique business model.
By eliminating overproduction, much more of your hard-earned money goes into materials, construction and long distance performance, instead of excess stock, discounts and returns.
