Field Journal: Winter Layers

As seen in the Tried & True Winter 2025 issue

When the temperature drops and the wind starts to bite, everyone knows that layering up is the way to go. But have you ever wondered why piling on those layers actually keeps you warm? It’s not just about throwing on more clothes–it’s about doing it right.

The Science of Layering

Think of your winter layers like a well-built house. The outer layer is your roof, keeping the elements out. The middle layer is your insulation, trapping the heat inside. And the base layer? That’s your foundation, making sure everything stays dry and comfortable. Each layer has a job, and together, they create a system that keeps you warm even in the harshest conditions.

Start with a base layer that sits close to your skin and wicks away moisture–think merino wool or synthetic fabrics–to keep sweat from cooling you down. Add a middle layer for insulation, like fleece or a lightweight down jacket, to trap heat without adding bulk. Finally, finish with an outer layer that’s windproof and waterproof to shield you from the elements while still allowing moisture to escape. This combination keeps you warm, dry and ready for whatever winter throws your way.

Why It All Matters

Layering isn’t just about staying warm–it’s about staying comfortable and dry while you’re out there getting the job done. It’s also science! When you layer-up right, you can adapt to changing conditions by adding or removing layers as needed. It’s a simple strategy that keeps you working efficiently, no matter what winter has in store. Next time you’re gearing up for the day remember to keep it smart, keep it practical and stay warm out there.
