I'm a full-time wildlife photographer and I sometimes guide photography workshops, as well. I live in these pants - they are hands-down the best outdoor pants I own. Being an hourglass shape, it's next to impossible to find to pro pants that are suitable for my work. These have a great length, and I love the internal drawstring that allows me to customize the fit - a MUST for anyone hourglass shaped who is a few different sizes from waist to hips to thighs. The pockets are thoughtfully designed and actually usable without extra bulk.
Whether I'm at home in Alaska working with brown bears or in the Pantanal of South America, I have these with me. I own them in all colors but one (will order as soon as it's back in stock in my size), and outside of my pair of pants from Gnara, these are all I wear. They hold up to climbing, scampering, and boring things like driving around, too. The water beads up on them nicely when I have a little rain and they allow me to move without any restrictions.
The only thing that could possibly improve them is to have a Gnara option in these like the overalls. The women on my trips all immediately want to know who makes my pants and I cannot rave about them enough.
