SteriPen Nalgene Bottle Backpacking Adapter

Love the trail and love my gear!

This adapter will work with a wide mouth Nalgene bottle and SteriPen Adventurer Opti. You may have to play with the x and y scale to fit your bottle. I liked the idea of inverting the bottle while zapping bugs but no device was available for this odd shape zapper.
You do not have to remove the adapter to install the cap or to drink from the bottle.

Have fun and be safe!
