Can't speak on behalf of Klim, but I've been completely satisfied with my FXR Nitro series gear. I've used it in every range of temp, and have never been to cold or warm. The jacket came with the liner, but I haven't used it yet. If I were to gripe about one thing it would be the moisture the guts of the jacket/pants collects from my "wick away" under garments. If you break sweat while digging out (Which I do alot) the moisture will wick directly from your body into the insulation, and build up. I don't notice it while riding, but at the end of the day, you can feel it in the jacket and pants.
