Be prepared and always hydrated with Sawyer 32-oz. Water Pouches. These replacement pouches attach directly to the tapered Sawyer filter, turning lake, river and bad faucet water into something delicious, refreshing and perhaps life saving. What's more, they collapse and roll up, using minimal space so you don't notice they are there until they are needed. Pouches only. Per 3. Wt: 2.56 oz.
