I just bought those angling gloves, and my first impression is very good. The green and white parts are fleece, while the gray parts are some sort of neoprene. On both hands the tip of thumb and index finger can be slid of and fixed in position with those round velcro pads. I doubt I'll have a chance to run them through a real test before the weekend, but just for kicks I held my hand out the car window while driving at about 80kph / 50mph (outside temperature ca. 0°C). I felt a lot of wind and cold through the gloves, but after a minute inside the car I noticed no difference between both hands any longer. I guess that means they kept in the warmth my body pumped back into my hand pretty well.
