worth it

I'm reasonably new to riding - some early mornings in spring and my ears and forehead got super cold - so I thought id try this - and I was really surprised at how well it worked considering at first I thought it was too thin.. it keeps my head and ears out of the wind and warm, even in the sunshine it does not cause my head to overheat - excellent value for money and i cant see me leaving the house without it again.

Warm and versatile

Great under a ski or cycle helmet. I carry one as a spare ski hat in my rucksack too.

Decent product for wearing under cycle helmet , however a bit pricey

Perfecto para el frío en los oídos. Necesitaba algo por el estilo ya que con temperaturas bajas un oído me acababa dando problemas y desde entonces nunca mas!


Se ajusta muy bien para ser talla única, soy muy friolero de orejas ,las cubre perfectamente.

Justo donde se necesita

Si quieres te tapa orejas. No sobresale excesivamente del casco

Muy cómodo para ir en bici en tiempo fresco

Muy cómodo para llevar debajo del caso en tiempo fresco. Tapa bien las orejas, y da una sensación de calor agradable, y por otra parte transpira bien.

Lo he devuelto

Creo que no está bien diseñado. La goma es muy fina y aprieta bastante. Cuando lo llevas 5 minutos ya tienes la marca en la frente. Es como llevar una corona de espinas, así que lo devolví. Utilizo otro que sacaron hace años marca Kalengi, para running, con un elástico muy suave de unos 4 cm de ancho, más cómodo y corta el viento mejor que éste. Por desgracia está descatalogado, pero podrían volver a sacar algo así para bici.

Hola gracias por tu respuesta, lamentamos que el producto no satisfaga tus necesidades. Puedes acercarte a una de nuestras tiendas y realizar un cambio de producto, por uno que si se amolde a tus necesidades.

Cumple su cometido dentro de lo esperado. Para frío relativo (invierno en Barcelona por ejemplo).
