Comments about Outdoor Research Ferrosi Pants (Men's):

I use these as everyday pants. While the material may be thin, it doesn't show any sign of tearing or ripping apart. The sizing on these is the trick. I'm 6'3", 190 lbs, I purchased a size 34 and they fit EXACTLY; typically I'd buy a 32. The stretch in the pants gives plenty of comfort, so the next size up is usually perfect. The legs have a slim fit, not skin-tight, but it isn't quite baggy. There's elastic at the ankles to tighten it up if the need arises, and is hidden in a way that doesn't show unless you know it's there.

  • Waist:
  • Feels too small
  • Inseam:
  • Feels true to length
  • Was this a gift?:
  • No
