Our take on the Outdoor Research Men's Ferrosi Convertible Pants

The Ferrosi Convertible Pants are men's hiking and climbing trousers made from Outdoor Research's Ferrosi softshell fabric, which resists wind and light rain and carries a UPF 50+ rating. Zip-off legs turn them into 10-inch shorts when the day warms up, and the brushed tricot-lined waistband with an internal drawcord and metal shank button keeps them seated on the move. At about 19.4 oz they are mid-weight for a convertible, lighter than many nylon convertibles but heavier than dedicated trail-running shorts. Owners of the Ferrosi line praise the fabric's stretch and breathability; the trade-offs are the extra seams and zippers of a convertible and the fabric's limited protection in sustained rain.

About the Outdoor Research Men's Ferrosi Convertible Pants

The Ferrosi Convertible Pants are made from Ferrosi fabric, which is abrasion resistant and water resistant. The legs zip off, so the pants become 10-inch shorts and can zip back on when the weather changes. The removed legs can be stowed in a pack.

The pants have a UPF 50+ rating. An internal drawcord waist and a metal shank button closure secure the fit, and the waistband is lined with brushed tricot. Drawcords at the cuffs adjust the leg openings.
