We designed this baselayer with our best Mountain experts. This high neck technical baselayer features excellent insulating properties and is also highly comfortable. The Merino wool is mixed with Polygiene® in order to prevent body odours.

Skin fit

The Xenon is designed using a circular knit process, meaning it's made of a single continous piece, resulting in an extremely comfortable seamless fit on the body. The only seams are found where the sleeves meet the torso, and above the neck.



Sweat is natural and odourless, but mixed with textiles, it creates a moist, warm environment that is ideal for the development of odour-causing bacteria. It is this odour released by bacteria that leads to an uncomfortable sensation and itching.

IONIC SILVER by POLYGIENE® prevents the growth of bacteria and fungi at the source. To do this, POLYGIENE® uses low concentrations of silver salt (silver chloride), which has antimicrobial properties and is naturally present in water and soil. This odour control is possible because the technology is permanently embedded in the fabric and will not wash away.

    I purchased this shirt believing it to be 100% Merino Wool as shown in the detail description. Unfortunately, received it, I see that the percentage is only 25%, which obviously should lead to a much lower price. The return is only possible with shipment via post office, which is definitely inconvenient in 'normal' periods let alone under Covid: it would take hours. Amazon allows you to make the goods by receiving a Courier directly at random or at a pickup point. All because, I repeat, the description is misleading. Bad figure compessiva of Cimalp.

    Buona sera\r\nGrazie per il suo messaggio\r\nPer quanto riguarda la percentuale di lana Merino mostreremo le informazioni in modo più chiaro. Grazie per il suo promemoria. Il basso contenuto della miscela è volontario, in quanto fornisce un perfetto equilibrio tra il contributo della lana Merino e la durata e la morbidezza delle fibre sintetiche.\r\nPer quanto riguarda i ritorni, la nostra procedura è certamente un po\' lunga, anche se è gratuita. Ma abbiamo un sacco di prodotti non restituiti quando avevamo proceduto al cambio rapido del prodotto per soddisfare un cliente. E purtroppo abbiamo fatto la scelta di aspettare il ritorno del prodotto da ora in poi\r\nComunque, grazie mille per aver trovato il tempo di scriverci, il vostro feedback è prezioso. Buona giornata
