Synthetic vs Down Insulation: Which Should You Choose?

Choosing between a puffer coat with down or synthetic insulation depends on where and how you plan to wear it. Both offer warmth, but their insulation and weather performance differ significantly. What's the difference between a synthetic puffer coat and a down puffer coat?

Puffer coats typically use synthetic insulation, but down-filled puffer jackets contain natural duck or goose feathers. Down provides an exceptional warmth-to-weight ratio in dry, cold conditions. Synthetic-filled puffers, however, excel in versatility - they maintain insulation when wet, dry faster, and require less maintenance.

• Synthetic puffer coats: Water-resistant, retains warmth when damp, easy care, ideal for UK weather and active use
• Down puffer coats: Ultra-lightweight, maximum warmth in dry cold, require careful handling

Which is warmer: synthetic or down?

Down insulation offers superior warmth in extreme cold. However, premium synthetic insulation in modern puffer coats delivers impressive warmth while maintaining performance in wet conditions - making them more practical for everyday wear and unpredictable weather.

Are synthetic puffer coats good in the rain?

Yes. Puffer coats with synthetic insulation perform excellently in wet weather. The fibres retain their structure and insulating properties even when damp. Our Triathlon 2.0 insulated jacket and Blaze insulated jacket feature water-resistant shells for complete protection in rainy conditions.

Can you wear down-filled jackets in wet weather?

Down jackets lose insulation when wet, as moisture causes feathers to clump. While some modern down jackets feature water-repellent treatments, synthetic puffer coats remain the more reliable choice for damp UK conditions.

Why choose a synthetic fill?

Synthetic puffer coats offer the best balance of warmth, weather resistance, and low maintenance. They're perfect for trail running, hiking, commuting, and everyday wear - especially in the UK's variable climate, where staying dry is just as important as staying warm.
