Universal 5-in-1 Warning Jacket – Protection and Comfort in All Conditions

This versatile Delta Plus Optimum 3 work jacket combines functionality, safety and comfort. Designed for demanding working conditions, it provides protection from rain, cold and ensures high visibility. Ideal for both professionals and anyone needing reliable warning clothing.

The jacket is made of durable Oxford polyester coated with polyurethane, guaranteeing resistance to damage and waterproofing. Additionally, the seams are sealed, which increases protection against moisture. The 5-in-1 construction allows it to be adapted to prevailing weather conditions – it can be worn as a rain jacket, fleece or parka.

Functionality and safety first

Optimum 3 meets the EN ISO 20471 standard (Class 3), providing excellent visibility day and night thanks to the use of reflective strips. Class 3 means sewn-on and horizontal mounting, which increases the visibility range of the user. The zipper covered with a Velcro flap and adjustable Velcro cuffs provide additional protection against wind and cold.

The thoughtful design includes three pockets (including one internal zippered pocket) for storing essential tools and accessories. A detachable fleece-lined jacket provides extra warmth on colder days. The jacket also has detachable sleeves and wrist cuffs for a better fit.

Construction and materials

The jacket consists of several elements:

• Outer jacket: Oxford polyester coated with polyurethane with sealed seams – provides waterproofing and durability.
• Lining: Polyester taffeta – for thermal comfort.
• Detachable jacket: Oxford polyester coated with polyurethane with fleece lining (280 g/m²) and polyester fiber wadding – ideal as an additional insulating layer.
• Reflective strips: Sewn on to ensure high visibility.

Thanks to this combination of materials, the jacket is not only durable but also comfortable to wear and easy to clean. The fleece lining of the jacket provides extra thermal comfort, and the PU coating increases the breathability of the material.

Application

The Delta Plus Optimum 3 jacket is an excellent choice for construction workers, public services, transport, warehouses and people working in difficult weather conditions or in poor visibility. It will also be useful during winter work and everywhere where high visibility and protection from the elements are required.
