The Sentinel Online writes a kind-of-review about the Techwear market. It's not complete but faces some interesting details.

Let's start here:

Intelligent textiles, variously known as smart fabrics, electronic textiles, or e-textiles, have attracted considerable attention worldwide due to their potential to bring revolutionary impacts on human life," writes a professor at Wayne State University in Detroit on an international scientific symposium held in Japan last year.

Funny names - e-textiles etc. - even more I love the word Techwear. The focus will be the technology like in hardware, software, techwear ;-)

It's goes on with a number I did'nt know till now:

...jacket from Rosner and INFINEON Technologies is reportedly even washable. ....
The initial production included only 600 units priced at about $760 each.

And an interesting market expectation:

Nonetheless, the companies claimed that, by 2007, total sales of "intelligent textile" products the world over would exceed $1.25 billion annually.

But even more interesting was a first user feedback - people who hassle with all-day problems:

Krips says he enjoys his music, but doesn't see the point in specifically marketed music devices such as the Oakley Thump, an $400-plus product that combines of ocular sun protection with an in-the-ear DJ.

"I'm afraid I'd break it," he adds.

I was afraid about just that too - and the lack of sound quality...
