A Men’s Baselayer for Every Season

Made to be the first thing you put on and the last thing you take off, Under Armour men’s baselayer clothing helps serve as a second skin that lets you perform no matter the weather conditions. HeatGear® helps you stay cool when the weather gets hot, ColdGear® keeps you warm when things get chilly, and UA Base 2.0, 3.0, and 4.0 keep you ready for every activity.

When it comes to our men’s baselayer clothing, Under Armour has got you covered for pretty much every season, and every sport or activity.

Our men’s baselayer clothing with HeatGear® is built for when things get hot. HeatGear® compression baselayers hug your muscles yet allow you to move comfortably in every direction. Plus, HeatGear® wicks sweat and dries quickly so you don’t overheat.

Flip the switch over to our men’s ColdGear® baselayers. ColdGear® keeps your warm when the weather gets chilly. Shop our men’s ColdGear® leggings. They’ve got dual-layer fabric that brings a warm interior and a smooth exterior that dries fast. 

Shop our UA Base™ men’s baselayer clothing. UA Base 2.0 is made for high activity in cold weather, 3.0 is made for moderate activity in very cold weather, while 4.0 is for low activity levels in extreme weather. UA Base 4.0 is our warmest baselayer yet. UA Base uses a pattern designed to trap heat without adding the extra bulk.

Whether you’re hitting the gym or enjoying the great outdoors, our men’s baselayer collection is your go-to choice for unbeatable comfort and performance.
