Also..make sure you're comparing the 2014 and later versions of the 90% pants...as they are much different than the past models. I own the Core4 Element softshell pants, and I love them (2013 model...earlier models had a different fit). They are burlier than the current 90% pants, and I like that they have knee pads, crotch vents and thigh zippers. The 90% pants lack some of these features...but they are probably lighter and more wind resistant. I use my Element pants a lot during spot and stalk rifle season...so for me...the Core4 fits my needs more. However...I usually wear a 90% jacket with them.
