How do you guys prevent odor in extreme situations?

I work in an extreme environment. Its about 91 degrees right now, but most days it reaches to about 95-98 depending on time of day. Its 12 hour shifts so im cooking in that heat for a long time. I work with furnaces and I am required to lift 150-250lbs about 10-15 times a day. Obviously standard deodorant was not built for this. Normally around halfway through the shift I can smell my feet and armpits if I stay in the same place. My coworkers understand because we all smell like ass, but I am used to being on top of my hygiene and I dont like smelling bad. Do any of yall construction/steel worker bros have any secrets to smelling good?
