When it gets chilly I wear a tank top (tank or t-shirt style) for warmth. This one fits well and is nicely built. Personally I would never use this as a solo top but I imagine you could if needed. Merino wool is great for wearing for more than a day and the tank top style means you don't have to worry about smelly armpits. It's only gotten through a few standard wash/dry cycles so can't speak to long-term durability but 'so far so good'. Would buy again.
