The SP-1 Tiger Camo is part of our Summer Drop series of limited run prints of some of our favorite patterns. The SP-1 is an innovative backpack accessory for storing your kicks during travel. The dual compartments are made of a heavy duty poly blend and each have a neoprene sole that allows the bag expand to hold larger shoe sizes. The front and back adjustable straps allow you to wrap the bag around most backpacks. Each compartment has a strategically placed vent to provide ventilation and keep your shoes fresh. (*sizing NOTE. If you are a borderline size and wear shoes with wider soles, please size up to the next available.)
