Wear as a Jacket..... OR convert it into a hiking jacket without the sweaty back from backpacks or bags! There are 2 interchangable back options! 

This has an INTERCHANGEABLE MESH BACK PANEL. Although our design works and will be used mostly without a back, we are offering a mesh back panel. This panel is completely interchangeable with the puffy back panel and uses the same YKK zippers. This allows you to wear the Pak-Jak as a normal jacket while still getting some additional airflow to your back.
