Hi Borja,

sorry for my late answer…
Also for me English is not my mother language…
Thx for appreciating my hair piece/attachment ;-)
Now I ordered the Aufero as suggested by Hersute, I try it, but I think I have to live it a little bit longer on the hear (tested it with 7-8 minutes), or buy the darker one… Now is quite better, but is not yet perfect.
About your question on sweating during sports and thin skin, for me this is not a problem, this thin skin has a good transpiration and I never felt some sweat not going out from the hair piece. But I think this can also be individual, I’m a middle sweater. Can be that other guys here on the forum have other experience?
If someone is interested, in attachment some pictures of me without hair piece ;-)

Regards
Alessandro
