I received my three pair of Outdoor Research Ferrosi pants about 10 days ago. The first thing I noticed when I opened the package on the first set, was a tag stating the pants have an "Infinite Warranty", to whit: "We believe so strongly in the quality of the apparel and gear we make that if our product fails to meet your needs at any time, we are happy to replace it. Our products are guaranteed forever, and your total satisfaction with our product is our goal."
Being me, my first thought was "Sheesh I bought two more pair of these than I needed!" ;-)
The pants fit great, really low profile seams, belt loops and pockets. They're designed to be worn under a saddle and if sized correctly, really don't need a belt. The range of motion is outstanding. I just wish my body had the range of motion that these pants will allow! The fabric has sort of a crepe texture. The pants have adjustable bungee bands at the bottom cuffs, which allow you to tighten them over the tops of your boots. You can also pull them up above your knees and tighten the bungees to convert them into shorts, which I'll probably do when I'm wading on waterfronts pruning mangroves.
I spent a day climbing in the Ferrosis, with nothing but good things to say about them. They wick extremely well. In conjunction with a Gildan Anti Microbial Performance long sleeved polyester t-shirt, Exofficio Give & Go Boxer Briefs, and Wigwam men's merino wool comfort hiker socks, I've never been more comfortable working in hot humid weather. I spotted short sleeved Adidias polyester performance T's at Costco for $10, and popped the collar of one over my head, then pulled it back up to catch all my hair, tucked the short sleeves down the front of the neck of my long sleeved T-shirt, and let the rest of the short sleeved one fall down from my helmet to cover my neck and back like a shawl. It was a super $10 solution to a wicking skullcap headband and neck shade, and moved moisture away from my head very effectively. The slightest breeze starts drying out all the fabric, cooling you in the process. My face was the only part of me holding any perspiration.
I dragged brush on a site the following day and had several instances where broken twig ends gouged into the fabric. No rips snags or tears. Light rain and dirt slides right off of them, and after a day of climbing or ground work, they wash up and look new. I'm entirely comfortable wearing them while doing consulting work.
All told, $357.08 got me 3 pair of climbing pants, 6 pair of socks, 5 long sleeved safety green performance T's, 1 short sleeved performance T, and 4 pair of boxer briefs.
