Despite the strength of Nano Silk and its ability to lie flat and disappear on small and micro flies, some tyers prefer traditional material for their fly tying thread.


Semperfli developed Spyder Thread aimed at the traditional market where fine threads like Gordon Griffiths CobWeb is used.


Spyder thread is a colour-fast semi-translucent two twist polyester based fly tyers thread, available in 18/0 30 Denier, has a 15% stretch and has a breaking strain of 14oz 390g.


This allows Spyder thread to lay flat on the hook and as a semi-translucent thread it will appear to be natural colour for wet, dry and nymph flies.
