The use of nanotechnology with silver fibres prevents bacteria from developing even after excercise, so you can stay dry and odour-free!

The difference in the details:

  • Two-material design with bodymapping
  • Ergonomic cut
  • No odour even after 100 washes!

For the specialists...

SMART DRY FIBERS for optimal moisture wicking thanks to double layers: the inner layer doesn’t stick to the skin, the external structure helps evaporate moisture.

Please note that for hygiene reasons, underwear and boxer shorts cannot be exchanged or returned. If you have any doubts about your size, please feel free to contact us for assistance.

How does it work?

Sweat is natural and doesn’t smell. However, when you add fabrics to the mix, this creates a warm and humid environment which is an ideal breeding ground for the bacteria that cause bad odours. It is the odour emitted by these bacteria that leads to discomfort and itching.

IONIC® SILVER by POLYGIENE® prevents the growth of bacteria and mould at source. Permanently. To achieve this, POLYGIENE® uses a very low dose of silver salt (silver chloride), naturally present in water and soil, for its antimicrobial properties. This technology is integrated into the fabric and is not eliminated with washing, meaning that these odours are always kept under control.
Is this good for my health?

The permanent POLYGIENE® fabric treatment is approved by bluesign®, which means that it meets rigorous independent standards for the environment in every stage of the product lifecycle. It is also on the Oeko-tex (I-IV) list of independently tested and certified products.

The treatment is made in the EU and is compliant with strict environmental standards.

After a steep climb when ski touring I found that my underwear was wet with sweat ... but after 10 minutes I was dry with no unpleasant feeling. Tested for two days. It's good material

A good underwear synthetic, especially since the entire part between the legs is mesh. No friction. Three small defects: - an annoying label on the inside on the side. - a very wide elastic that increases the weight of underpants - does not dry very quickly (more than cotton, less than other technical fabrics. The anti-odor techno works properly, but do not expect to wear for more than two days in my opinion.
