All About That Base (Layer)

When the frost bites and the trails call, the right base layer isn’t just gear—it’s your foundation for adventure. Whether you're carving through New Hampshire's backcountry on a snowmobile or stargazing at the end of a long day, staying warm, dry and comfortable begins with the right base. Let’s break down why base layers matter and how to choose the perfect one for every adventure.

Why Base Layers Are Essential

Think of your base layer as your first defense against the cold. It regulates your body temperature, wicks away sweat and keeps you comfortable, no matter how rugged the conditions. The key? Choose a base layer that matches your activity level and the weather.

From morning snowmobile rides to post-ride cocktails, the correct base helps make every moment count.

Types of Base Layer Materials and How to Choose

Not all base layers are created equal. While there are many products out there to love, different fabrics are best for various activities. Here’s how to pick the right fabric for your next outing:

Merino Wool: Naturally odor-resistant, warm and temperature-regulating, merino wool base layers are perfect for low-to-moderate outdoor activities or multi-day trips.

• Best for: Longer outings, the coldest weather and comfort-first adventures.
• Our pick: Kari Traa Else Half-Zip Base Layer

Natural Blend: For a slightly lighter-weight winter layer, a natural blend is soft, durable and warm for more intense activities.

• Best for: Medium intensity activities, activities where lightweight matters.
• Our pick: Kari Traa Voss Cashmere Half-Zip

Mixed Blend: Temperature-regulating, moisture-wicking and durable, mixed blend base layers are ideal for high-intensity activities where you need moisture to wick away from the skin.

• Best for: High-intensity activities when you’re going to be getting sweaty.
• Our pick: Kari Traa Rulle High Waist Pant

Synthetic: Quick-drying and moisture-wicking with optimal stretch, synthetics are your go-to for high-intensity adventures in slightly warmer weather. Synthetics also tend to have a lower price point than natural fibers.

• Best for: Sweaty trail rides, active days and warmer conditions.
• Our pick: Kari Traa Mille Half-Zip or Klim Aggressor Shirt 3.0

How to Layer Like a Pro

Layers allow you to stay warm and dry, no matter what you’re doing or how cold it gets. Remember, with layering, you can always shed a layer if the day gets warmer, but you never want to be underdressed when hitting the trails. Also, keeping a spare base layer in your pack is essential for emergencies or post-ride coziness.
