I found a windproof, softshell vest by Black Diamond at Costco for $20. It works great for 35 to 50 degrees. Above that, and it's a little too warm. Below that, and I'd prefer something heavier (such as 1: my $30 softshell Black Diamond soft shell jacket from Costco; 2: my softshell Cloudveil Serendipity, very expensive ($130 on clearance), not as water resistant as the Black Diamond, but more breathable; 3: my $99 hardshell J and G Cyclewear waterproof jacket).
