Field Pants that offer comfort, function and can be paired up nicely if worn outside of work.
A top to go with the season or weather, and it needs to be BRIGHT! You want to make sure you are seen while out walking around.
Everyone has a preference on their unique underwear needs and wants, these are some either I or teammates have found to work well! Most, if not all listed below also have a boxer/boyshort equivalent.
A sock could make or break how your day will go - I would recommend something thick, will dry quickly, and, if available, something with a bit of compression. Mine also have to be the most vibrant colors - but, thats just me.
Overalls are a great addition for fieldwork!
A necessary evil when working outdoors - this is very much a matter of personal preference and what personally works for you. These are what I have been using and what work for me.
