READ: Your Guide To The Layering System / Base Layer Buying Guide

Your performance in the mountains depends on a layering system that functions flawlessly. This range of men's base layers provides the critical first layer, built to manage your microclimate so you can focus on the objective. Each piece is made to work with your body, moving moisture and regulating temperature from the skin out.

Maintain a stable core temperature. Our base layers use two primary material strategies. Choose technical merino wool for its unmatched ability to regulate temperature and resist odour on multi-day efforts. For high-output activity, select our advanced synthetic base layers, which move perspiration with exceptional speed to keep you dry when the pace is high.

Move without restriction. These base layers are cut with an active, trim fit that layers cleanly under other apparel. We use flatlock seams to eliminate chafing under pack straps and gusseted panels to ensure a full range of motion. These are not just details; they are fundamental to distraction-free movement in technical environments.

Select the right tool for the conditions. This range includes lightweight tops and bottoms for mild conditions and fast-moving pursuits. For deep winter, choose our midweight and heavyweight options for increased insulation.

Thermals are a type of base layer designed specifically for colder conditions, offering enhanced insulation to retain body heat. Base layers, on the other hand, focus on moisture-wicking and temperature regulation, making them versatile for various climates and activities.

Base layers should fit snugly but not restrictively. A close fit ensures efficient moisture-wicking and traps warm air against your skin for insulation. Loose base layers can lead to heat loss and reduced performance.

Merino wool base layers are the warmest due to their excellent insulation and ability to regulate temperature.

Yes, base layers are essential for staying warm, dry, and comfortable during outdoor activities. They wick moisture away from your skin, prevent chafing, and regulate body temperature in various conditions.

Yes, lightweight or midweight base layers can be worn alone in mild weather or during high-intensity activities. However, heavier base layers are typically used as part of a layering system in colder conditions.

A base layer is worn closest to the skin to regulate body temperature, wick moisture away, and provide comfort during physical activities. It helps keep you warm in cold weather and cool in warmer conditions, making it versatile for various outdoor pursuits.

Merino wool is ideal for cold climates due to its warmth, moisture-wicking, and odor-resistant properties. Synthetic fabrics like polyester are durable, quick-drying, and better suited for high-intensity activities. Hybrid blends combine the benefits of both.

Lightweight base layers are suited for mild weather and high-intensity activities, while heavyweight options provide more insulation for colder conditions. Choose based on your activity level and climate.
