Fishing Balance Pockets are 12-liter bags designed to attach to the front of Aarn backpacks, compatible with all models except Minilites. They can hold two fly boxes measuring 19.5 x 11 x 4 cm and two smaller fly boxes at 16 x 10 x 4 cm. The smaller front pocket features a flap that opens into a horizontal shelf. Additional storage includes two external mesh pockets and two elastic loops on the front. The air-mesh back panel provides ventilation, while the lower back is wire-stiffened and the upper back flexible for comfortable forward bending. Made from durable ripstop nylon in grey, these pockets measure 30 cm high, 12 cm wide, and 11 cm deep, weighing 450g per pair. Delivery takes 5-10 days.
