No matter where you live there are "cold" days that require a little extra bundling!
For those days here in San Diego, or if I travel to cold climates, I have these secret little layering pieces that make quite a difference!
My favorite is the Uniqlo tank. I have had it for years and not only do I love the extra warmth, the tank itself is my favorite go-to for layering! Uniglo has a whole line of Heattech products(for guys too) and the prices are amazing.
