Also sizing and cut plays a part to it. The fit needs to be snug and layered so perspiration is immediately taken away from the body instead of lingering around on your skin.
+1 for Polartec Neoshell also, great material as it has more give in it than eVent. You can cut the jacket even more snugly as you don't feel the pinch across the shoulders when stretching. But the weight gain is noticeable. Equivalent Rab jackets in Neoshell and eVent are around 40% heavier in the Neoshell. Great material though.
