Triathalon (or other) backpack. Tons of compartments. Super useful.

Front compartment built to hold helmet. Lots of other zipper sections - for shoes, phone, wet clothes, water bottles etc. Top is drawstring closure to accommodate awkward sized things. Hard to take photographs. If you are needing something like this - you know what you are looking for and this is a great backpack. My husband used this when he was training for a triathalon. No more triathalons in the future ;)
