Assos combines **OSMOS Light** for light insulation with **SPHERE Ultra** as an ultralight softshell panel in the crotch area that blocks wind and spray without overheating you. The new, more breathable and antimicrobial chamois is based on the floating construction of the summer shorts and stays protected behind the softshell, keeping warmth dry. The **AEPD 11 racingFit** delivers the typical second-skin fit for maximum stability, available in 7 sizes from XS to 3XL in the **blackSeries**. - **OSMOS Light** thermal textile for light, active insulation and **SPHERE Ultra** softshell protection at the core. - Aerodynamic **AEPD 11 racingFit** with **Louvre Tec** at the knee to prevent friction during pedaling. - **Soft compression Module** at the waist for stable support without restriction in athletic position. - **X-Frame** bib layout stabilizes lower back and chamois during intense intervals. - **Raw Cut** leg endings for friction-free layering with overshoes and **reflective details** on the lower legs. - New **EQUIPE RS S11** chamois with **Shock-Absorb Damping System Mono 9**, **3D Waffle**, **kraterCooler** and **whirlKrater** for pressure relief and airflow. ## Technical Details and Features The tights use an ultra-soft, breathable thermal textile as the main body and are complemented in the crotch area by a light **SPHERE Ultra** softshell panel that protects your core from headwind, spray and light moisture. Crucially: The panel doesn't store excess heat, so you won't overheat under high pressure – ideal for intervals and race loads in spring and autumn. The **AEPD 11 racingFit** wraps the muscles with 360-degree compression, while **Louvre Tec** shapes the knee so the fabric doesn't shift during pedaling. **X-Frame** bibs prevent the chamois from sagging, **Raw Cut** endings reduce volume at the ankle, and subtle **reflective details** increase visibility. The material composition is 54% polyamide, 30% polyester and 16% elastane – functionally chosen for support, drying time and durability. ## Applications and Benefits These bib tights are your go-to for **cool, dry conditions** on the road bike – perfect for brisk training on Züriberg, long base rides in the Mittelland or punchy climbs in the foothills. The softshell panel shields the exposed torso against headwind and spray, while **OSMOS Light** actively regulates temperature. The breathable, antimicrobial chamois keeps the seat climate comfortable without allowing cold drafts in sensitive areas. Combine the tights with a spring-fall jersey or vest depending on weather conditions and add **ASSOSOIRES** as needed for more protection. This gives you stable performance, dry warmth and a precise feel that convinces even during pace changes. ## Fit and Sizes The **racingFit** is athletic-compressive and sits like a second skin, which brings stability and efficiency especially on long intervals. If you're between two sizes, choose tighter for more compression preference or one size larger for a bit more freedom of movement. The RS 2/3 Bib Tights S11 come in 7 sizes from XS to 3XL and in the **blackSeries**, making it easy to combine with your existing Assos gear. For care, we recommend delicate wash at low temperature, quick air drying and avoiding fabric softener so the elastane and chamois retain their performance. This way you'll make the most of the tights' strengths in the Swiss transitional season long-term. ## Variants - 11.14.279.18.3XL: in stock - 11.14.279.18.2XL: in stock - 11.14.279.18.S: in stock - 11.14.279.18.L: in stock - 11.14.279.18.XS: in stock - 11.14.279.18.M: in stock - 11.14.279.18.XL: in stock --- Source: https://kilometro.ch/en/products/knickers-tights-665/rs-23-bib-tights-s11-478
