Quick answer
Start with a moisture-wicking athletic tee as your base, add a lightweight insulating mid-layer, and finish with a breathable shell. Avoid cotton at all costs.
Why your base layer matters most
The athletic tee you choose as your first layer determines how well your whole outfit manages sweat and temperature. A fabric that traps moisture will leave you cold and clammy, especially once you slow down or step into the wind.
Look for tees made with synthetic blends—polyester and spandex—that wick moisture away from your skin and dry quickly. The Men's Athletic Tee - Raspberry and Women's Athletic Tee - Strawberry both use a 92% polyester / 8% spandex mesh that does exactly that, plus they offer UPF 50+ sun protection if your cool-weather run takes you into midday sun.
The trade-off: warmth vs. breathability
More layers aren't always better. If you over-insulate, you'll overheat and sweat through your base layer, defeating its purpose. The goal is to feel slightly cool at the start of your workout—your body heat will warm you up within the first five minutes.
A lightweight, breathable athletic tee like the ones from Nature's Bakery (4.42 oz/yd²) gives you enough coverage without bulk. Reserve thicker fabrics only for truly cold days (below 40°F) when you need a thermal mid-layer.
Step-by-step layering guide
- Step 1: Choose a moisture-wicking base tee: Put on a synthetic athletic tee like the Men's Athletic Tee - Raspberry or Women's Athletic Tee - Strawberry. Avoid cotton—it holds sweat and will chill you once you stop moving. If your tee feels damp after a warm-up, it's not wicking properly.
- Step 2: Add a lightweight insulating mid-layer: Over your base tee, wear a thin fleece, a long-sleeve synthetic top, or a light vest. This layer traps body heat without restricting movement. Zip or unzip to vent as needed. A mid-layer that's too thick will make you overheat before you finish mile one.
- Step 3: Finish with a breathable outer shell: Choose a wind-resistant or water-resistant jacket that still lets moisture escape. Look for pit zips or mesh-lined vents. If it's dry and not too windy, skip the shell and rely on your first two layers. A non-breathable shell will trap sweat and make you cold once you stop.
