The North Face Men's ThermoBall™ Trekker Jacket

Synthetic Warmth That Never Quits.

The North Face ThermoBall™ Trekker Jacket is built for the long haul. Packed with ThermoBall™ Eco synthetic insulation that mimics the loft and warmth of down — even in wet conditions — this is the insulated layer that keeps performing when natural down falls flat.

• ThermoBall™ Eco insulation — synthetic clusters that retain warmth even when wet, made from recycled materials
• Warm when wet — unlike down, ThermoBall™ doesn’t lose its loft when exposed to moisture
• Lightweight & packable — stuffs into its own pocket for on-the-go versatility
• DWR-treated shell — water-resistant finish sheds light rain and snow
• Full-zip front with chin guard — draft-free closure protects against wind chill
• Zip hand pockets & chest pocket — secure, organized storage for essentials
• Elastic cuffs & hem — locks in warmth and keeps cold air out

Whether you’re trekking above the treeline or navigating a cold city commute, the ThermoBall™ Trekker delivers reliable warmth you can count on.
