This is a very fine monofilament micro fibre. It is available in 14 colour shades. In most cases it is spooled as two twined micro fibres.

Being very thin, thus inconspicuous, but firm at the same time, this tying thread is very popular with Czech fly dressers.

With Synton even the smallest flies can be tied. However, fly dressers can use it for flies of all sizes.

By using this material, one can create fly bodies that are very small flies, even partly transparent.
