The main valve for Anfibio Packraft from Anfibio Packrafting should not be missing on your next discovery tour on the water. It is a replacement for the main valve or cap and ensures that you always have a replacement with you even if you lose the main valve and do not have to cancel your rafting or kayaking trip with your Anfibio Packraft. The replacement valve is small, handy and takes up almost no space in your backpack.
