I like simple long sleeved shirts without logos in the winter. Wearing scrubs at work I always needed long sleeve undershirts. I came across the Healing Hands brand on Amazon. They’re cheap to buy but hold up well. I have one that I’ve worn weekly for three winters in a row and it’s still holding color and seams great! Highly recommend these for comfort.
