I had one of those that I wore as a liner under a Carharrt jacket to work in. Worn alone, it eventually ripped to shreds getting caught on nails, lumber, wires etc... There's no reason you couldn't use it in the conditions you describe. I live and hike in a far colder climate, so for me, I'd rather have something a little warmer and versatile to backpack with. I have a Patagonia fleece I bought in the 70's that I still am using. I also picked up a Patagucci fleece vest for 5 bucks in a thrift store that I've had for 6-7 years. As they say, paint don't make the car run faster, but i don't mind quality (expensive?) gear when I'm in demanding situations.
