This is for the straw only, the cap is not included as per the photos. without being able to buy the cap renders this useless unless you already have the Eddy lifestraw combo bottles. I didn’t want to waste the bottles I already had that have lasted years and still going strong. I have found another method to convert my older chute style camelback bottles to Lifestraw filters with caps

Just like to carry spare filter handy and so will last for a very long time filtering water.

This is great when you regularly drink city tap water, although having to buy one for 30+ dollars every 1.5 months does add up

If you own the Largest camelback Eddy + bottle then don’t buy the largest Eddie plus filter. The large does not fit the large bottle for some reason and there is no descriptions of what the filter fits and won’t fit.

After the delivery the filter is too large for the 32 Oz bottle. Aggravating because I precisely needed the filter change for my trip. Dumb to present 3 filter sizes w/o indications.
