Did you know that the waterproof coatings on your favorite hiking boots, backpack, tent, or other camping gear may be leaching toxic forever chemicals into your bloodstream and the environment? 

Since the 1940s, manufacturers in many industries, including the outdoor equipment industry, have added per- and polyfluorinated substances (PFAS or alternatively, PFCs) to coatings on products to make them more resistant to moisture, dirt, and oil. The danger of these “forever” chemicals is that they never break down, leading to widespread contamination of the natural environment. They’re also linked to a variety of adverse health effects, including cancer and hormonal disruption.

The good news is that you can protect yourself and the environment by buying gear from companies that have already banned PFAS or are currently phasing them out.

[Editor’s Note: Unfortunately, PFAS are now ubiquitous in our environment. Therefore, when we say “PFAS-free,” what we really mean is that PFAS are not intentionally-added to products. Technically, it’s still possible that minimal amounts of PFAS can make their way into products through manufacturing. However, the recommended brands below are making every effort to avoid PFAS in every way possible.

On another note: You’ll notice that in other places on The Filtery, we recommend avoiding synthetics when possible (like with clothing and bedding, for example). When it comes to outdoor gear, however, we take a different approach. Synthetic fabrics such as nylon can help provide water-resistance, prevent mold/mildew growth, and last a long time. In our opinion, it’s better to have a PFAS-free synthetic tent, for example, than a tent made from organic cotton but that is either treated with toxic PFAS or can’t hold up to the elements.]
