Outdoor Research Ferrosi Pant vs Outdoor Research Ferrosi Convertible Pant

Buy the Ferrosi Pant for most hiking, climbing and travel. It is lighter, has a softer waistband and a simpler build that owners praise for breathability and stretch. Buy the Ferrosi Convertible Pant if you regularly hike through changing temperatures and want pants and shorts in one. It weighs noticeably more and the zip-off legs add bulk, but the versatility is real. Both use the same Ferrosi fabric family, so wind resistance, quick drying and UPF 50+ are close.

  • Choose the Ferrosi Pant if you want the lighter, simpler pant for climbing, hiking and everyday wear.
  • Choose the Ferrosi Convertible Pant if you want one garment that switches between pants and 10-inch shorts on the trail.

Outdoor Research Ferrosi Convertible Pant

Questions and answers

Which is better for hot-weather hiking?
The Convertible Pant, because you can zip the legs off into 10-inch shorts mid-hike. The standard Ferrosi breathes well but stays full length.
Which is better for climbing?
The standard Ferrosi Pant. It is lighter, has a softer waistband under a harness and no knee zippers to rub against a harness or rock.
Does the convertible version last as long?
Generally yes, and the ripstop fabric resists abrasion well. The zip-off seams and sliders are the parts to watch over years of use.
Is the standard Ferrosi worth stepping up to if I already want shorts?
Only if weight and simplicity matter more than versatility. If you often hike in changing temperatures, the convertible saves you carrying a second layer.
Do both fit the same?
Both use a standard fit and a harness-compatible waist. The convertible runs heavier and bulkier through the leg because of the zip hardware.
Are both good for travel?
Yes. Both are quick-drying, wind and water resistant and UPF 50+. The standard Ferrosi packs smaller; the convertible covers more climates in one garment.
