jrc wrote a review of Patagonia Knifeblade Softshell Pant - Men's on June 30, 2014
Familiarity: I've put it through the wringer
Fit: True to size
The Good: Fabric breathes well for a membrane soft shell, nice and thin so you can layer appropriately for conditions, quite weather resistant as others have noted, good pocket position, minimal design = light weight!
The Bad: Patagonia fit flub. Seriously terrible, terrible design for a supposedly athletic pant. I'm 6', 180# and 33 waist. I have a size M. They are not trim enough for climbing and they're not baggy enough to look good skiing. They are slightly baggier above the knee than below but not even remotely trim enough to be considered an athletic/european/climbing fit. As such, they look absolutely ridiculous. Go try on a few of the euro brands and you will see what true ergo oriented designers can do. Often they still fit over ski boots! All patagonia had to do was take their old alpine (or even backcountry w/o the vents) guide pant design and change up the fabric. They would have had a 5 star product right out of the gate. Too many compromises on this pant and the result is a pair of really really expensive hospital scrubs with suspenders....who wants suspenders!?!? They fall off your shoulders and just create more hassle. These aren't even a true bib that you could say significantly improves resistance to powder snow. Classic patagonia bringing a great idea to its knees with fit. My guess is this material is so expensive they had to give up on the features and design work to make them anywhere near affordable.
So get something else you might say? No, I'm sucking on the crack pipe of power shield pro and I want more. These have been resort skiing, backcountry skiing and alpine climbing in california and france and they're the only pant I can imagine taking on an expedition as my only pant (+ base layer). Plus, at 60% off from the patagonia outlet store, I suppose I get what I paid for in fit. Hopefully I can destroy them by the time a euro brand makes a decent competitor.
