I needed one for my lab work this fall, so I went down to Chemstores and picked one up. It's blinding white cotton twill, with a breast pocket, two hip pockets, and two side slits so I can access my pants pockets easily.
I giggled madly all the way home. And then Doc gave me a pocket protector, and I died of the giggling. Snerk.
Okay, I am off to collect on the St. Joe for a few days with the herbarium crew. Catch you later.
