Daiwa Pier 39's Tech-Ex Weather Pants are that guy. Made from 100% nylon, these pants feature a wide-leg fit that ensures freedom of movement, while the breathable mesh lining adds comfort.
Designed with practicality in mind, the elastic waist with an adjustable drawstring allows for a customisable fit. In true Daiwa Pier 39 fashion, these have more pockets than you can count on one hand (they have eight).
Last but definitely not least, they have water repellant capabilities so they can handle more than your average pair of pants can.
