Gear Guide
We gather and analyze gear reviews so that you buy right the first time. Our team of professional outdoor journalists bring back objectivity, transparency, and authenticity to buying gear. We want you to choose something that won't go to a landfill or hog up space in your garage. We're dedicated to making an inclusive outdoor space where everyone—regardless of how you do the outdoors—can make smart gear decisions.
Buy less junk. Help the planet. Gear for everyone.
