Review on Columbia Women's Mighty Emerald Small Clothing and Coats, Jackets & Vests by Steve Washington

It's AMAZING! This vest is my lifesaver in winter! I live in Michigan and winter is one thing. I already wear a down jacket every day, but I have a hard time staying warm because my coat doesn't fit snugly to my body. I wear this vest under my coat as a base layer - it's so thin it fits perfectly! - and I could take my dog for long walks without getting cold to the bone. I'm size XS which fits if you're looking for a vest to wear over a coat or sweater but as expected if you're looking for a base layer. I usually wear XS-size tops and XS-S-size coats.
