Size Guide

Product manufactured in Portugal.


Reinforced yarn combines ultra-fine Merino wool to provide exceptional softness, natural insulation and moisture-wicking properties that keep you warm, dry, and comfortable even in the harshest outdoor conditions. The addition of a synthetic filament to the Merino adds extra durability and strength to the fabric, ensuring that your base layer will withstand the toughest outdoor adventures.

The long sleeve design offers added coverage and protection, while the stretchy, form-fitting construction allows for complete freedom of movement. The lightweight and breathable fabric makes it an excellent choice for outdoor sports such as running, hiking, and skiing. 

Our Merino base layer is also naturally odour-resistant, making it perfect for multi-day trips or long hours on the trail. And when it comes time to wash, it's easy to care for and maintain, so you can spend more time enjoying the great outdoors. The main body is knitted in a single piece to provide seamless comfort and snug fit with flatlock seams elsewhere to prevent rubbing and chaffing. 

Whether you're hitting the trails, skiing the slopes, or just enjoying the great outdoors, our Merino base layer has got you covered. Experience the unbeatable comfort and performance of Merino wool for yourself and elevate your outdoor sports game to the next level!
