$34.95
★★★★★4.7(5,200 reviews)

The Sawyer Squeeze SP129 is the most trusted backcountry water filter on the market — and for good reason. Its 0.1-micron absolute hollow fiber membrane removes 99.99999% of bacteria (including salmonella and E. coli) and 99.9999% of protozoa (giardia, cryptosporidium). The kit includes two 32-ounce BPA-free squeeze pouches, a drinking straw for drinking directly from water sources, and a hydration pack adapter that threads onto most reservoirs. Rated for up to 100,000 gallons with proper backflushing, this is a lifetime water filter that weighs just 3 ounces.

Why You Need This

You're tired of carrying 8 pounds of water up a mountain, or worse — running out of water halfway through a hike because you didn't trust the stream water. You need a filter that's light enough to forget about but reliable enough to bet your gut on.

Pros & Cons

  • Threads directly onto Smartwater bottles and most hydration reservoirs

❌ Cons

  • Squeeze pouches can develop pinhole leaks after extended use
