Seal Fur is fantastic for fly tying however the legal protection of seals make this product hard to find. Semperfli's R&D and Pro teams have developed the most realistic seal fur substitute possible. SemperSeal Subs is the resulting product, with the perfect feel for your dubbing. Semperfli deliberately manufactures SemperSeal in long fibres. It's not only perfect as a Seal Fur substitute, cut to a fiber length of 0.5 to 0.75 inch (12 to 18mm), but also can be used as full length 3 in. (75mm) fibres making it ideal for Saltwater, Steelhead, Predator and Salmon fly patterns.
