Pro GSP Thread
Fulling Mill Pro GSP Thread is an ultra-strong, fine-diameter, twisted gel-spun thread built for tyers who need strength without bulk. On our coloured deniers, colour is manufactured directly into the thread, so it will never run.
- Deniers: 30, 50, 100, 150
- 30 & 50 denier — strength with minimal build-up; perfect for midges, small dries and small nymphs
- 100 & 150 denier — built for streamers, saltwater patterns and predator flies; the go-to thread for deer hair streamer heads
- 4 colours: White, Black, Olive, Tan
- 100 metres per spool
