The Helly Hansen Chelsea Evolution BRZ Jacket is a 4-way stretch, lightweight softshell men's work jacket built around Helly Hansen's BRZ climate-regulation technology. At 94% polyamide with 6% elastane, the main fabric delivers exceptional stretch and recovery for unrestricted movement across the full range of trades working positions. The BRZ ventilation system - mesh ventilation panels and a ventilation opening at the back - actively manages body temperature during high-output site work without requiring the wearer to stop and remove layers. This is a trades jacket for the conditions that don't quite need a waterproof shell but do demand something more than a base layer. The lightweight construction means it won't add unwanted bulk to a layer system, and the practical pocket arrangement — chest, hand and ID card loop — keeps the working day properly organised. Available in Black or Navy, with reflective design details for improved site visibility.
