This is Semperfli’s smallest Nano Silk and is sized at 24/0 or 20 denier. It consists of 12 filaments and can be split for even finer strands. While this GSP is 17 times stronger than steel of the same diameter, it has a low specific gravity so it floats on water. Its extremely small diameter allows for uses requiring no build-up including tricos and midges.
