Our mission: create the world’s best outdoor gear reviews.

Have you ever wanted to buy an outdoor product and been stumped about which product is best? Or, worse, bought a product only to learn later that you didn’t buy the right one for your needs? I have, and that is why I started OutdoorGearLab.

The OutdoorGearLab mission is simple: to create world’s best outdoor gear reviews.

My only complaint is that eventually, backflushing won’t be enough. These can clog up after some time and no amount of back flushing will fix its low flow. I went through 2 on the AT. However, it will attach to Smart Water Bottles and most bladders!

Built for backcountry reliability and portability, the Sawyer Squeeze filter is our pick for the best portable water purifier.

The Sawyer Squeeze was (by far) the most common Pacific Crest Trail water filter this year – for the fifth year in a row. It’s a $39, 3 oz / 85 g hollow fiber filter that rids your drinking water of protozoa and bacteria (and floaties). It can be used with Sawyer bags (included with the filter) or with compatible water bottles (Smartwater is the bottle of choice for many hikers).
