The best pants for three season hiking, buswhacking or summer mountaineering, at an excellent price. They're soft and don't trap sweat, but they're durable enough for bushwhacking and rock climbing. Excellent performance and great value.
I use these as climbing pants and they're great! Very lightweight and breathable, with plenty of stretch. The drawstrings on the leg are a huge plus as I like to roll up my pant legs when I climb.
When I bought these pants I thought they were convertible so I was disappointed to find out they were not and the color (mushroom) wasn't quite as brown as I thought they would be. I wanted to return them but after trying them on soon found out that I really like them . They are light , they dry fast and offer some sun protection. They have an adjustable elastic cuffs so you can pull them up as shorts if you need to. Great from kayaking and hiking very comfortable great for traveling you can get away wearing them for any occasion.
Fit is great. Thought they wouldn’t hold up well but they seem to be almost bulletproof. Wear them for most of my outdoor activities and they show very little wear.
I bought two pairs on the initial drop, a brown pair and a tan pair.
Even though they are loose on me, the back of the belt/fly button digs into the skin below my navel, so much so that over extended use the discomfort becomes uncomfortable. I can't believe that the product testers/evaluators at OR missed this. They're now relegated to collecting dust in a bag somewhere.
Also the fabric snags on everything and doesn't breath very well. More of an urban/travelling pant than an outdoor hiking/activity pant.

This is marketed as a climbing pant but I use them as hiking pants.
I ordered two of these pants (ferrosi) as I was between sizes so got the 32 and 34 inch waist.
The fit is loose and if you have muscular glutes and thighs erring on the small leads to tightness over the seat.
that said, there is plenty of stretch in the pants so i would order a smaller size for more athletic activities and a larger size if you want to use the pants for travel/leisure .
They are a goldilocks pant - good for hot or cool activities (for reference - i use them in 30-35 degrees hiking in Australia)
The fabric is very light and air permeable but also has significant wind blocking properties - I use the smaller size for walking and even mountain biking. The length is true to size and the cuff can be easily gathered by the elastic in the cuff. I like the lower waist which is a bonus in more athletic activities.
I personally am happy with the pants but would prefer them in a closer fit to the leg - they do run baggy.
