Perfect For

Whether you're heading out on a multi-day alpine trek, skiing in the backcountry, or simply need a reliable everyday base layer, this merino top delivers consistent comfort across a wide range of conditions. Its slim profile makes it the ideal first layer under a softshell or insulated jacket, while its natural breathability means it works just as well during high-output trail running or yoga sessions.

Why Choose This Base Layer

Not all base layers are created equal. At 17.5 microns, this merino wool sits in the ultra-fine category — soft enough for direct skin contact without any itch. The 180gsm weight strikes the sweet spot between warmth and packability, making it a genuine four-season performer. Pair it with your favourite MSE Outfitters mid-layer for a complete system built for New Zealand's variable mountain conditions.
