Here are a couple of the new FL products. They also came out with a woman's baselayer specific line as well. The new synthetic pants and the gaiters are on my list to grab.
The redesigned Kanabs have two panels of stretchy material (one in the crotch and one--if I remember correctly-- above the seat) that allow for more flexibility, range of motion without stressing the pant. I think they also have a zippered rear pocket and different closures on the cargo pockets. I have a much older pair and the new ones look like they'll solve all of the issues I've ever had with them
the pants sealed the deal for me. thats the only piece i felt they were missing was a good lightweight synthetic pant. Ill be putting my order in as soon as they are available.
