3FREE backpack 3rd proto

May update. In April and May, we made several proto and this is the 90% finished 3FREE backpack. We still have idea to make it better. We are using it everyday and going to test in coming King Of Track cycling race at Korea on next week. The final version will be done after the trip. Please wait for our update.
