The most popular filter just got smaller and lighter. The Mini weighs just 2 ounces and filters up to 100,000 gallons! What's special about Sawyer filters is they filter to 0.1 micron absolute, exceeding EPA and NSF recommendations. Did we mention you can drink directly from the Mini, attach it to Sawyer Squeeze Pouches, use inline on a hydration pack, or attach it to the top of almost any bottled water? How about that for versatility? And like all Sawyer Filters; they are backflushable almost indefinitely. That means no expensive cartridges to replace, ever. Kit Includes: 1 - Sawyer MINI Water Filter with Tip Cap 1 - 16 oz Reusable Squeeze Pouch Mfg: Sawyer
