A superb quality GSP thread in different thread weights. The 30 denier is the thinnest strongest thread for its size that we know of.
In the heavier sizes its perfect for Saltwater flies and for spinning deer hair.
You also get 75 meters of thread per spool which is more than most other companies offer.
Three sizes available.
Tom Davies –
GSP Thread is excellent for the smaller flies and Klinkhammer’s 50den is probably the most versatile and very strong.
