I bought these for biking but they quickly evolved into my preferred travel pant. I have the wine colour (that doesn't seem to be available any longer). I keep coming back to look for new colours, so I'm buying my second pair in black today.
Since they are designed for a flexed-hip position, they are great for sitting in a plane. They are warm, but not too hot, even when it's warm outside. Ticks and poison ivy love me, so I will stay covered even if sweating. They are stain resistant for turbulence. They are great for hiking (see photo: Beehive in Acadia) The side zips are big enough for your passport, phone, sunnies, a small snack and that trail map all folded up because you won't have reception. I get compliments every time I wear these, usually in airport lounges where seasoned travelers are in awe of my pockets.
If I could make one suggestion: more colours please. Navy, dark taupe, even high vis colours for hunting season. Paisley? Yes please! Plaid? Hell ya!
