The FlyTrap insert allows for great storage of both fully hackled dries or rows of nymphs.  Waterproof boxes have a gasketed lid and Secure Latch Closure.

Silicone Inserts:

  1. Durability: Silicone inserts are known for their durability. They can withstand repeated use and are less likely to degrade over time compared to foam inserts.
  2. Easy Insertion and Removal: Flies can be inserted and removed from silicone inserts with ease. The smooth surface of silicone allows flies to slide in and out without snagging.
  3. Water Resistance: Silicone is inherently water-resistant, which means it won’t absorb moisture. This can help protect your flies from damage caused by wet conditions, reducing the risk of rust and mold.

Foam Inserts:

  1. Fly Security: Foam inserts typically feature small slits or indentations where flies can be securely held in place. Once inserted, flies are less likely to dislodge or become tangled during transportation.
  2. Versatility: Foam inserts can accommodate a wide range of fly sizes and styles, including dry flies, nymphs, and streamers. The compressible nature of foam allows it to conform to the shape of the fly, ensuring a snug fit.
  3. Affordability: Fly boxes with foam inserts are often more affordable compared to those with silicone inserts. This makes them a budget-friendly option for anglers who are just starting out or need multiple boxes for different fly types.
