How to Layer for Autumn: Fleeces, Softshells & Base Layers

Autumn brings unpredictable weather - chilly mornings, mild afternoons, and damp evenings that challenge teams across a variety of sectors.

Without the right layering system, your team risks discomfort, cold stress, and reduced visibility.

Choosing adaptable workwear ensures your staff stay warm, visible, and productive, whether they’re working outdoors all day or moving between.

At SMI, our range of fleeces, softshells, bodywarmers, and base layers is designed to perform in all conditions, helping you build the right system for your team.

Why Layering Matters in Autumn Workwear

Layering gives your team control, flexibility, and adaptability.

Instead of relying on one heavy garment, multiple lighter layers let staff adjust to changing temperatures throughout the day.

A well-planned system:

• Improves focus and productivity
• Reduces risks linked to cold stress
• Regulates heat and maintains comfort
• Keeps workers visible, dry, and compliant
• Maintains visibility and compliance with HSE guidance and EN ISO 20471 for hi-vis clothing

The three-layer system explained

Effective layering follows a simple three-step principle - base, mid, and outer layers. Each plays a distinct role in comfort, protection, and performance.

1. BASE LAYERS - MOISTURE AND HEAT REGULATION

Base layers wick away sweat to keep skin dry and body temperature stable. They’re essential for teams moving between warm and cold environments.

What to look for:

• Lightweight thermals or long-sleeve tops
• Materials like polyester, merino wool, or blended fabrics
• Breathable fabrics suitable for hybrid indoor/outdoor roles

2. MID LAYERS - INSULATION AND COMFORT

The mid layer provides warmth without bulk. Fleece is ideal because it’s soft, breathable, and easy to move in.

Top picks:

• Fleece jackets: versatile warmth-to-weight balance for everyday wear.
• Hi-vis fleeces: combine insulation and visibility in one garment, perfect for site work.

3. OUTER LAYERS - PROTECTION AGAINST THE ELEMENTS

The outer layer shields against wind, rain, and snow while maintaining breathability. Softshells are a flexible, all-weather choice.

Options to consider:

• Softshell jackets: lightweight, flexible, and water-repellent.
• Hi-vis softshell jackets: provide added visibility and protection in low-light conditions.

Practical layering tips for your team

Layering needs differ depending on the role and environment.

Here’s how to approach it:

FOR OUTDOOR ROLES

Combine a thermal base layer, fleece mid layer, and waterproof or hi-vis outer shell for full protection. Reflective details improve safety during darker mornings and evenings.

FOR INDOOR OR HYBRID ROLES

Choose lightweight, breathable fabrics. These materials can easily adapt to changing temperatures and keep your team comfortable all day.

CARE TIPS FOR WORKWEAR

To maintain performance, wash garments at low temperatures with mild detergent and avoid fabric softeners. This helps preserve insulation, water repellency, and durability.

Always follow the guidance on the inner care label.
