If you know there is the potential of packing out four miles are so would you carry the filter with you each day in your pack along the water in you camelbak or water bottle? I thought I might need it simply becuase you never know how long you' ll be out.

i bought the Katdyn micro filter it weight about 20 oz but I think it will last a life time its good for like13000 gallons or some ridculious number like that?

Would you carry it in your pack??
