Why Compression Base Layers Are Not Great At Keeping You Warm

Compression base layers are often touted for their performance benefits, but when it comes to warmth, they might not be the best choice. Understanding why compression base layers fall short in providing adequate warmth can help you make better decisions about your cold-weather gear. Here’s why compression base layers may not keep you as warm as you’d hope.

1. Primary Function is Compression, Not Insulation

Compression base layers are designed primarily to enhance muscle support and reduce fatigue by providing a snug fit. Their main purpose is to improve circulation and reduce muscle vibration, rather than to offer significant insulation. As a result, they might not provide the warmth needed for cold weather.

2. Limited Insulation Properties

Compression base layers are typically made from materials like Lycra or spandex that focus on elasticity and fit rather than insulating properties. These materials do not have the thermal insulation capabilities of materials of specialised synthetic fabrics designed to trap and retain heat.

3. Reduced Air Trapping

Effective insulation relies on trapping warm air close to your body. Compression base layers are designed to fit tightly against the skin, which limits the amount of air trapped between the fabric and your body. This reduction in air insulation can lead to less warmth compared to more looser-fitting, insulating base layers.

4. Less Moisture-Wicking Efficiency

While compression base layers are good at wicking moisture away from the skin, they often lack the same level of moisture management as some thermal base layers. In cold conditions, moisture management is crucial to prevent chill and maintain warmth. Less effective moisture-wicking can contribute to feeling cold.

5. Potential for Overheating

Compression base layers can sometimes lead to overheating during high-intensity activities. Although they manage moisture well, their snug fit and material may trap heat, potentially leading to discomfort if you’re not regulating your body temperature properly.

6. Not Ideal for Layering

When it comes to layering for warmth, it’s essential to have base layers that offer both insulation and moisture management. Compression base layers are often less versatile for layering compared to other thermal base layers that are designed to work as part of a layered system.

7. Better Alternatives for Warmth

For better warmth, consider base layers made from materials specifically designed for insulation, such as performance synthetic fabrics used in Sub Zeros Factor 1 Plus range. These provide better thermal regulation and insulation, keeping you warmer in cold conditions.

Final Thoughts

While compression base layers offer benefits like muscle support and moisture-wicking, they are not the best choice for keeping you warm in cold weather. Opt for base layers with superior insulating properties to ensure you stay warm and comfortable during your outdoor activities. For high-quality thermal base layers and more gear tips, visit Sub Zero.
