The perfect addition to any outdoor excursion!


  • Fit
  • Breathability
  • Material flexes with you as you move


  • Tends to pill around pack straps, etc.

I wear the OR Ferrosi soft shell in every season! It's the perfect outer layer in the summer when I need something breathable, soft on my skin when worn over a t-shirt, and warm enough to allow me to rest and soak in the view atop a chilly summit. In cooler temperatures, it's a welcome addition to any layering system. I often wear it beneath the OR Aria Vest and on especially cold days, pile on a hard shell over both.

I love the Ferrosi material— it's flexible, allowing you to move without restriction, yet doesn't lose its shape. I have a small torso and find that other soft shell layers can feel too boxy or need to be cinched tight, creating bunching, which can be uncomfortable under a pack or outer layers. The Ferrosi has a slim fit without ever feeling restrictive, even when worn over a few base layers. 

I have noticed that the material tends to pill on high abrasion areas, like when worn beneath the waist belt of a pack. This seems purely aesthetic as I haven't noticed any breakdown in the material and I've owned mine for over a year now. 

Here are some photos from a recent snowshoe trip worn beneath the OR Aria vest. This is a layering pair I highly recommend.

This is a lightweight soft-shell jacket that provides great protection from the wind and light rain while also remaining very breathable and stretchy. This makes the Ferrosi jacket ideal for a wide range of outdoor activities.


  • Lightweight
  • Breathable
  • Stretchy
  • Durable fabrics


  • A little baggy around the waist

The overall fit of this jacket is pretty good and the jacket is very comfortable even during strenuous activity. I'm 5'9'' and about 135 lbs. and a size small fit me very well with the exception that the jacket is just slightly baggy around the torso area.

The Ferrosi Jacket is a full zip jacket with elastic cuffs and a shock cord drawstring at the at the waist. The jacket is very wind resistant and will shed a light drizzle; however, in heavier rains this jacket will become soaked through.  This jacket breathes very, which makes it ideal for hiking, backpacking, skiing, and even on windy jogs. When using this jacket on an early spring backpacking trip, I was able to keep this jacket on steep uphill climbs still remain cool and dry inside the jacket.

This jacket is not insulated or fleece lined, so it is not very warm. However, there is enough room underneath this jacket wear an insulation layer in cooler temperatures. The jacket's material is very durable and abrasion resistant.  It has not developed  any signs of wear on the back or the waist after carrying a heavy pack.

This jacket has 3 pockets—1, chest and 2 waist level—which are large enough to store energy bars or a pair of gloves.  In addition, one of the waist level pockets doubles as an integrated stuff sack for the jacket.
