Assos ThermoBooster Bib Tights S11

The ThermoBooster S11 pushes versatility to the extreme, allowing a number of use cases to adapt throughout winter. For cycling, it layers over your preferred summer shorts without adding the bulk of a second insert. In the most extreme conditions, it adds an additional thermoregulating layer to any Spring Fall or Winter bib tights from the R and TACTICA series. For cross-training, the ThermoBooster adapts to skiing and running, adding an additional element of reflectivity to your workout. However you employ it, the raw-cut finishing and low-volume insulation reduces bulk for layering, unlocking an entire system of winter layering for any outdoor training.

Features

• FEATURED FABRICS: RX EVO Plus is the most thermally insulating of the RX EVO family. It resists odor, wraps the large muscle groups in asymmetrical stretch, and traps body warmth with low-volume thermoregulation. The warp knit resists abrasion, and it stays black rather than showing white elastic while stretching.
• Our streamlined, unisex regularFit and body-contoured shaping reduce seams, eliminating friction for total comfort and easy layering. Raw cut waist and ankles finish with a gently compressive, bulk-reducing hold.
• zeroPressure waist: A waist construction developed with a soft, highly elastic material to improve the comfort and hold at the waist, minus any pressure or pinching.
• X-Frame: A suspension design originally engineered for the Racing Series. Limits sag on the lower back, stabilizing the insert and main body panels.
• Reflective: Large stripes on the lower legs increase visibility in low-light, overcast conditions, flashing light throughout the pedal stroke.
