Pants for Hot Weather that Look Similar to Outlier Slim Dungarees

I own a pair of Slim Dungarees, love the look but need something else for the summer. I want the same look but much stretchier pants for hot weather. I love running, especially along the beach. I much prefer pants to shorts. The Dungarees look awesome and made with an exceptional attention to detail but are not comfortable in hot weather and active pursuits because they don't move with the body. They have very little stretch to them, run too warm, and stick to my legs in 90 degree temps - it makes for an uncomfortable experience. Is there a pant (by Outlier or other brands) that looks similar to the Dungarees but made for highly active lifestyles in hot weather? I need something thinner and more breathable. I'm looking for very-high quality pants -- similar to Outlier. I don't have a budget/cost is not an issue. I'm going to be wearing the pants with brown leather sandals. Khaki or blue color pants would be nice. What are my best pant options?
