Guideline Slim Tri Foam Fly Boxes

Guideline Slim Tri Foam fly boxes are made from durable, crystal-clear polycarbonate and are designed for storing dry flies, nymphs and streamers. Their slim profile makes them easy to carry in fly vests, packs and pockets. The 15 mm internal height provides enough space for larger dry flies, including parachute patterns and upwinged flies, without excessively crushing their wings. The lime-coloured foam insert gives good contrast against most fly patterns and helps make them easier to see. The Medium version measures 15.6 × 10.7 × 2.7 cm, weighs 112 g and provides 130 slits for securing flies. The Large version measures 18.6 × 13 × 2.7 cm, weighs 165 g and provides 204 slits. Slim Tri Foam boxes are a practical choice when you want to carry selected fly assortments or organise different groups of flies in separate boxes for specific fishing situations.
