The Ultimate Guide to Choosing the Best Base Layers for Outdoor Adventures

A high-quality base layer is the foundation of any outdoor adventure, whether you're hiking, skiing, cycling, or braving cold conditions. The right base layer helps regulate body temperature, wicks moisture away, and provides comfort during any activity.

In this guide, we’ll explore the Nano Range and Summit Range base layers, compare synthetic vs. merino wool, and help you choose the best option for your needs.

What Is a Base Layer & Why Do You Need One?

A base layer is your first layer of defense against the elements. It helps:

✔️ Regulate body temperature – Keeps you warm in cold weather and cool in warm conditions.
✔️ Wick moisture away – Prevents sweat buildup to keep you dry and comfortable.
✔️ Control odor – Essential for multi-day adventures.
✔️ Provide durability – Resistant to wear, tear, and pilling.

Different materials serve different purposes. Let’s break down the two most common types of base layers: merino wool vs. synthetic.

Nano Range vs. Summit Range: Which Base Layer Is Right for You?

Nano Range – High-Performance Synthetic Base Layers

The Nano Range is a hypoallergenic, synthetic base layer designed for high-intensity activities like cycling, running, and hiking. It’s ideal for those who need quick-drying, moisture-wicking, and durable performance.

Best for: High-output activities such as running, cycling, and hiking in mild to cool conditions.

Summit Range – Premium Merino Wool Base Layers

The Summit Range is made from 100% Merino wool, offering natural warmth, breathability, and odor resistance. It’s perfect for those who need a next-to-skin layer for extended outdoor pursuits.

How to Choose the Right Base Layer

Choosing the best base layer depends on your activity level, climate, and personal preferences. Here’s what to consider:

Activity Level

• High-intensity activities (cycling, running) → Choose the Nano Range for its quick-dry, lightweight, and moisture-wicking performance.
• Cold-weather & multi-day adventures → Opt for the Summit Range, which provides insulating warmth and natural odor resistance.

Climate & Season

• Warm & mild conditions (spring, summer, fall): Choose Nano Range (205gsm) or Summit Range (180gsm) for breathability.
• Cold conditions (winter, alpine hikes, snow sports): The Summit Range (260gsm) is the warmest option.

Durability & Sustainability

• If you need a tough, long-lasting base layer that resists pilling, go with Nano Range (synthetic).
• If eco-friendliness is important to you, choose the Summit Range (merino wool), which is biodegradable & renewable.

Final Thoughts: Which Base Layer Should You Choose?

The perfect base layer depends on your outdoor activities, climate, and personal preference.

Choose the Nano Range if you need a quick-drying, moisture-wicking, and abrasion-resistant synthetic base layer.

Choose the Summit Range if you want natural warmth, odor resistance, and breathability with sustainable merino wool.

Pro Tip: Many outdoor enthusiasts use both – synthetic for high-output activities and merino wool for cold-weather adventures.
