Columbia Women's Plus Size Mighty Lite III Vest - Lightweight Down Puffer Vest for Outdoor Activities, Hiking & Casual Wear

I have different sets of vests/jackets/coats for each season. OCD. In Fall and Spring I have thin Tek Gear ones with down filling. When this arrived, It felt just a little bit thinner then those. I also ordered the Dahlia for winter so I was worried. I also have an anxiety disorder. It's for 50-55 degrees no matter the season. I tested it today. It's about the same comfort level as the Tek Gear ones even though it's a little lighter.The omni heat thing works by keeping in body heat. If you are wearing it for a run, I'd imagine it's great!!! It just wasn't what I needed for the every day. Even with a sweater under it in the low 50s. I wasn't cold, it just wasn't as warm as the Tek Gear ones I have. When I wore it for a long walk, it was how it was supposed to be though. Bottom line, it's great if you're going to be doing enough exercise to create body heat!I have regular sized boobs and it fits great. Although, I did order a size up because of the sweater. It's called "bluebell". You'd assume it was blue not purplish. It's the color of the actual flower bluebell. So, for me, the color was as expected. I recommend ordering a size bigger anyway.
