Mens Base Layers

The right base layer makes all the difference when you are out in the cold. At Outdoor Adventure Store, our men’s base layers are designed to keep you warm, dry and comfortable from the first step of your hike to the summit. Whether you prefer the natural softness of merino wool or the quick drying performance of synthetic fabrics, every layer in our range has been tested for Irish conditions.

Top brands like Icebreaker, Helly Hansen, Berghaus, Dare2B and Trespass deliver reliable insulation, breathability and moisture management. Choose long sleeve thermal tops for winter hikes, or lightweight short sleeve layers for year-round use. Many of our merino options are naturally odour-resistant, while synthetic designs excel in wicking sweat away during intense climbs.

These base layers work perfectly under a fleece or waterproof jacket, giving you a versatile system for changing weather. Built for the mountains, not the high street, they are a must-have for anyone who loves the outdoors.
