I purchased the Kokatat Polartec liner for my GMER drysuit and I have used it a few times while both sea kayaking at 38 degrees and surfing a sit-on-top in January with the air temperature of roughly 40 degrees.
As the previous reviewer mentioned, I felt the cold but did not feel cold. I also had a thermal top and bottoms on under the liner. I don't know if that made a large difference or not. The liner fits great, does its job, and is well worth the money.
My only complaint is that it started to pill really quickly and I have fleece pills all over the place.
