Pawikan or Sea Turtle is one of the animals that will go extinct in the near future. Its role in the ocean’s eco system is invaluable and critical to human survival. Still people do not take notice. We honor this design for everyone’s awareness. Lined with cobalt blue ripstop fabric which features multiple rubber mesh pockets and keyhook. It also has rubber mesh compartment for a 15” laptop and pockets for documents. Its volume is large enough for a travel backpack as well. The stunning feature is the mountain bike shoulder strap. The contrast of the textured tire strap to the plain innertube shell body gives the impression of sea turtles. Sea turtles are among those directly affected by floating garbage in the world’s oceans.
