Narrative:

During initial climbout; at approximately 8;000 MSL; the captain reported smelling the dirty sock odor. I noticed it as well; and donned my oxygen mask. I left the mask on for the next ten minutes. We called the flight attendants; who did not report any unusual odor in the cabin. The fumes subsided in about five minutes. I did not notice any physiological symptoms. We continued the flight with no further issues. Suggestions: provide training to flight crew; cabin crew; maintenance; and ground crew on the dirty sock odor - recognition; reporting; physiological effects; etc.; to raise awareness. Develop a checklist specifically for dirty sock fume events. Attempt to determine root cause of these events at [company] (oil over-servicing? Etc.).
