If you open up a drawer–any drawer–and find a gel flask, you’ve probably raced some mountain bikes*.
Or you are just an unorganized doofuss like me that throws your shit wherever and then spend hours looking for it in the time leading up to a long ride or a race. Note that there is no cap for the flask. I am pretty sure I saw it on top of the dryer in the basement.
*OK, you might not race mountain bikes but you do SOMETHING equally as cool yet unpopular and misunderstood by the general U.S. public: ultra runs, adventure racing, cross-country skiing, etc.,
