Guideline WP Fly Boxes are lightweight and durable fly boxes made from ABS material. The water-resistant seal helps keep flies dry when wading deep or fishing in heavy rain.
The boxes are easy to open thanks to the larger grip on the locking mechanism. Their generous internal depth allows larger dry flies to be stored without excessive squeezing. All versions measure 196 × 106 × 42 mm and are sized to fit well in fly fishing vests and packs.
The Double Side Slit Foam version has 9 rows of slit foam on each side, with 10 mm between rows. It is suitable for dry flies, wet flies, nymphs or a mixed selection. The lower side is deeper and can accommodate larger dry flies with taller wings. This version weighs 201 g.
The Slit Foam Swing Leaf version has 36 rows of slit foam and offers generous capacity. The deeper side is suitable for larger dry flies, while the shallower side works well for emergers, nymphs and other less bulky patterns. The hinged swing leaf stays in place during use and can be easily removed. This version weighs 243 g.
The boxes are slate grey with an orange seal and a Guideline snake logo on the lid.
