Do you have size XLT

What is slit in one sleeve?

Boat work must have long sleeve shirts will these keep me dry & cool for hot , humid south Fl summers?

My chest size is about 41", so i'm probably an m, but i prefer a bit of bagginess. would l be too big, making the sleeves a bit like the puffy shirt?
