I've been thinking my camelback reservoir has been looking really nasty lately. Even my friends have noticed and mentioned that I really should get a new one. I never have owned a cleaning brush for it. I normally just run bleach through it. But those black spots seem to be very permanent.
So I bought a new one. It was only $17.00 to replace it.
And good news, I even bought a cleaning tool.
So, with 2 ultramarathons and 1 marathon in a 2 1/2 month period of time. I am now ready to go.
