¿Puedo usar el sotomono todo el año?

Sí. Para climas cálidos elige tejidos ultratranspirables; para frío, versiones térmicas con mayor gramaje o combínalo con una capa térmica ligera.

¿El sotomono sustituye a las protecciones?

No. Es una capa base que mejora confort e higiene. Las protecciones van en el mono, chaqueta o peto específico.

¿Cómo debe quedar de ajustado?

Ceñido y sin arrugas marcadas. Si notas presión excesiva o tirantez en hombros o ingles, considera una talla más.

¿Se puede usar bajo monos de cuero y textiles?

Sí. Está pensado para ambos, mejorando la colocación del mono y la evacuación del sudor.

¿Cada cuánto debo lavarlo?

Tras sesiones intensas o altas temperaturas. En rutas suaves, ventilar puede ser suficiente entre lavados.

Professional Motorbike Sotomones on BeRacing1

Optimise your equipment from the first layer. On BeRacing1 you will find sotomonos designed to improve comfort, breathability and performance on the road and on the track. Technical materials, ergonomic patterns and high-end finishes to keep you focused on riding.

Why use a sotomono?

Thermal comfort and sweat management: A technical under suit wicks away perspiration and accelerates drying, stabilising the body temperature under the suit. This avoids feeling damp, chafing and heat spikes.
Freedom of movement: Stretch fabric and flat seams reduce friction and allow for a snug fit without limiting mobility during changes of footing, braking and attack stance.
Hygiene and durability of your overall: It acts as a hygienic barrier, reduces odours and facilitates cleaning of the main equipment, extending the life of the leather or textile coverall.
Quick dressing and undressing: Improves the internal sliding of the overall, making it easier to put on and take off, even when perspiration is high.

Frequently asked questions

Can I use the sotomono all year round?

Yes, for warmer climates choose ultra-breathable fabrics; for colder climates choose warmer, slightly heavier weight versions or combine with a lightweight thermal layer.

Does the sotomono replace the protections?

No. It is a base layer which improves comfort and hygiene. The protections are attached to the specific overall, jacket or bib.

How tight should it fit?

Fitted and wrinkle free. If you notice excessive pressure or tightness in shoulders/hips, consider one size up.

Can it be worn under leather and textile coveralls?

Yes, it is designed for both, improving the fit of the suit and the evacuation of sweat.

How often should I wash it?

After intense sessions or high temperatures. On mild routes, airing may be sufficient between washes to preserve the fabric.
