Guideline Double Side Silicone Fly Box
The Guideline Double Side Silicone Fly Box combines a waterproof construction, premium silicone inserts and an intelligent double-sided design to provide outstanding protection and organization for your flies. Designed for modern fly anglers, it is particularly well suited for dry flies, nymphs and other bulky patterns whose delicate wings and hackles need maximum protection.
Silicone inserts on both sides hold hooks far more securely than traditional slit foam while offering a much longer service life. Because silicone grips hooks more efficiently, the inserts can be thinner, creating additional internal space for larger flies without increasing the overall size of the box.
What is the Guideline Double Side Silicone Fly Box?
This premium double-sided fly box features independently opening compartments, each equipped with durable silicone fly-holding plates. Unlike conventional foam inserts, silicone resists wear and maintains excellent hook retention even after years of repeated use.
A silicone sealing gasket between the two halves provides excellent protection against rain, splashes and water while wading, helping to keep your flies dry in demanding fishing conditions.
