We all own that one piece of gear we can’t live without. Maybe it’s your commuter bike (“It makes me love going to work!”). Or your dad’s old longboard (“It always finds the waves.”). It’s your favorite thing—and now you can give it the recognition it deserves in the pages of Outside’s 35th anniversary issue. Using the submission field below, tell us why, exactly, you love this one product so much. You can also submit a photo. Outside’s editors will select the best submissions. Entries are due by June 29. Also, find out other ways to contribute to our anniversary issue.
