No batteries required, so go ahead and get it wet. This little pump will never let you down when you need it. With no batteries to fry, go ahead and leave it strapped to your downtube when it’s a ‘mud year’, take ALL the river crossings, and commute with it through salt season.   Ready and waiting. All you’ve got to do is twist it open, air up, and race home. How easy is that? Hit the link in our bio to shop our entire EnCase lineup of pumps and tools. #wolftoothcomponents #encasepump
