I'd like to replace my Columbia PFG rain gear, which is effective but heavy. I'm considering going with a pullover jacket to eliminate the weight of the zipper. I know the trade-off is that it doesn't vent as well. For example, if I'm using it not in rain, but as a wind block, and I start to get a bit warm, I wouldn't be able to partially unzip it to cool off.

However, I wonder how much of a concern this really is in practice. I'm interested in hearing from anyone with actual experience with pullover style rain jackets and wind jackets/shirts, as I would use this for both purposes. I'm especially interested to hear from folks that have used one in a similar climate to mine (hot summer, mild winter [occasional freezes], and generally very humid).
