Warm and substantial - Mountain Hardwear Glacial Storm Vest - Men's

This vest is very warm. I've worn it over my work shirt at around 32 degrees F and felt fine and I've also worn it over a T-shirt on a windy day at around 50 degrees while bike riding and felt fine. It blocks the wind and keeps my core warm. The fit is about as expected. I am about 6'3" at 240 lbs, slightly athletic, and XL fit me just fine. It's not very heavy but it felt more "substantial" or durable than some other lightweight vests at the same base price point that I looked at. my only suggestion is to beef up the zipper a bit.
It's not tiny or fragile looking, but it could be heavier duty. Overall, I'm happy with it.
