Glad you liked them. I am also happy with the new river. Also chose it because of humidity here in FL. I have had it down to 28 degrees with a 20 degree sleeping bag. Back got a little cold with just a shirt and a t shirt. Had to put on my fleece jacket to get warm again plus I didn't have the ends cinched up enough and it let some cold in. But I am happy with getting into the high 20's with it. Paul makes good stuff!
