Too thin - Not the quality Columbia I'm used to

I was very disappointed to find that this vest wasn't the same thickness I have purchased in the past. I can't imagine this layer will be able to really keep me that much warmer as it's intended. What happened to the Columbia quality of old? My husband also received a vest for Christmas, and we were equally disappointed with that one for the same reason. His vest that I bought him 4 years ago is much thicker (aka much warmer to wear in below freezing temps). We were very disappointed.
