It features a dual-head design (28/30mm) that allows you to use standard 30mm bottled water in place of the original SAWYER water pouch — a practical, durable alternative when pouches wear out or aren’t available. Two key uses: 1. For connecting water bottles – Connect a 30mm bottle to your SAWYER filter for quick, on-the-go water collection setup. 2. Backflushing – Attach a 30mm bottle to the drinking end via the adapter to flush clean water back through the filter for maintenance. Includes two adapters. When combined with the original 28/28mm SAWYER adapter, this setup covers both forward flow and reverse flushing. Made from PE material — ideal for hiking, camping, and emergency prep.
