If you sweat a lot, you'll like Phin-Tech. It's the lightest shirt we tested and it moves moisture well. Sweat passes directly through the polyolefin fibers to the outer surface so the fabric stays dry effectively. This lightweight fabric is a much better choice than BiPolar 200 for a base layer unless it's bitter cold. Like the other shirts in this review, this one combines different inner and outer surfaces in a single layer.
Sweat migrates to the outside of the fabric, which keeps the inside of the shirt dry.
This technology explains why you feel dry even though your shirt is damp. This is one of the heaviest shirts we tested. It feels velvety soft next to your skin, and it's a toasty base layer for cold winter wear. Best for runners who live in extremely cold climates. This is a great shirt that feels soft next to the skin and offers maximum breathability.
