LifeStraw Peak Series - Large Capacity Gravity Water Filter System with Safe Water Storage - 8L + 8L for Camping, RVing, Overlanding, Travel and Adventure, Mountain Blue

The fourth picture does the best at showing the size of these. It might just look like she's wearing a small backpack in the picture, but that's actually ONE of the two bags that you get. So what all DO you get? Here's what's included, followed by some specifications:INCLUDES-- 8 liter gravity bag-- 8 liter safe water storage bag-- Hose with clip to stop flow + standard quick connector-- Membrane microfilter-- Pre-filter basket-- Leak-proof cap for water storage-- Carry strap and carabiner-- Backwash syringeSPECIFICATIONS-- Weight: 946 grams OR 33.7 ounces-- Volume: 2 gallons OR 8 liters-- Bag size: 23.5 x 13.9 inches-- Hose length: 1.2 meters OR 47.2 inches-- BPA-FreeThe instructions are pretty straightforward and the only other thing worth mentioning is the, "leak-proof cap," that they say is included. Don't worry, it is included, you just won't see it at first. That's because it is already on the gravity bag (the bag that would be the top bag). The whole cap on that one unscrews revealing the pre-filter basket, and the leak-proof cap is actually on the outside of the round cap itself, and can be removed by twisting it in a counter-clockwise direction.

Filters fast and thoroughly, this filter is a must have!!!!
