Wapsi SLF Saltwater Dubbing is a synthetic material originally developed as a replacement for seal fur dubbing. SLF is a genuine synthetic fiber dubbing, extremely popular and widely used for its unique translucency and realistic sheen.
All SLF products are developed by Davy Wotton - a well-known Welsh lacemaker.
In addition to saltwater patterns, SLF Saltwater is a popular dub for many nymphs and salmon flies.
