Nano Silk is the best GSP thread on the market – period! Super strong, this is the highest quality thread available. Never worry about snapping your tying thread again – you can rely on Nano Silk.

Nano Silk Pro 20D is considered the professional level being the finest of the range. 20d is also known as 24/0 – that is really very small indeed! That said this baby of the Nano Silk family has all the strength you would expect from this premier thread. It is 10 times stronger than steel of the same diameter! Nano Silk Pro 20D is fine enough for size 20 to 32 flies whilst still retaining its strength. Available in black and white, with 100 metres on each spool, if you dare, you can split this oh so fine thread further if required so dubbing on size 32 flies with split threads is a reality.!

Nano Silk Pro 20D is designed for micro flies down to size 32, however do not be fooled, Nano Silk Pro 20D is as strong as 8/0 polyester thread yet is less than 1/20th of the diameter. As a result it can be used for any fly where you do not want to see your thread.

You can tell you are using Nano Silk Pro 20D as its on white spools to differentiate it from the other Nano Silks. Please remember to use a ceramic bobbin holder
