- Come in five sleek colors
- Comfortable fit
- Reasonable price
- Breathable and fast-drying
The thinness of this shirt from MPG Sport gives it a second-skin feel, making it incredibly comfortable to wear. Crafted from a blend of Polyester, Merino Wool, modal, and spandex, this base layer strikes the perfect balance between cost-effectiveness and performance. While it may not be 100% merino, it doesn’t compromise on breathability and moisture-wicking properties.
It offers versatility with five sleek colors that are suitable for layering under outerwear or wearing solo on brisk days. We love that this shirt is made primarily from recycled materials, which aligns perfectly with outdoor enthusiasts’ eco-conscious values.
The only downside? It requires air drying after each wash, as it’s not tumble dry recommended.

Under Armour has long been a dominant name in the compression wear market, and its ColdGear® material lives up to the hype. “This base layer truly takes winter wear to the next level by keeping me warm, wicking away sweat, and maintaining breathability all at once,” says John Thompson, Senior Gear and Commerce Editor. The mock neck design is a smart choice for layering, providing excellent neck protection against the cold and wind on those chilly days.
The OG compression style fits snugly and conforms to the skin. This not only feels athletic and comfortable but also promotes an increase in venous return and improved circulation and prevents chafing. “Whether I’m hitting the gym or braving the cold for an outdoor run, the Under Armour ColdGear® Compression Mock has become an essential part of my cold-weather workout gear,” says Thompson.
