I have a crapload of Greg Norman/Shark Polos
moisture-wicking poly/cotton blends
I've had since 1999, with my co. logo, great shirts
from when I owned my Golf Pro-shop, more golf shirts really
I guess you could work in them, I have many times
just not filthy type work
If I know I'm going to get dirty/filthy
My construction work or mechanic apparel,
for when I know I'm going to be dirty
I wear a coverall jumpsuit
or when it's hot, my farmer john overalls (or shorts & a tee)
with a cotton shirt under it, long-sleeve for winter
short-sleeves for all other seasons
It is/they are all cotton, & all are 1 size bigger
because they shrink like hell especially in the dryer
even if you pull them out before they're dry
& let them sit at room temp for a while, they still shrunk
cotton breaths really well, it's also relatively cheaper
so does the moisture-wicking poly/cotton blends
& last way longer, but also more $$$ too
