Knox Men’s Frontier Waterproof Thermal Jacket



Super warm, waterproof jacket designed to work with the Urbane Pro & Zephyr Pro and can be worn casually.

The Knox Urbane Pro or Zephyr Pro are CE Approved abrasion-resistant armoured shirts that are designed to be worn on their own with no jacket required in warm weather.

However, they can be worn all year round by adding good technical layers. The Frontier jacket has been designed to fit comfortably over the top when cold and wet weather arrives for the ultimate combination of protection, warmth and waterproofness.



The Frontier jacket is a fully laminated, seam sealed, waterproof outer jacket, with a high-performance insulating lining.

The stylish outer jacket is made from a high-performance stretch tri-laminate soft shell and is lined with INVISTA’ THERMOLITE® PLUS quilted down-proof fabric on the inside which provides warmth and comfort without weight. Its hollow-core fibers trap in air for greater insulation and heavy-duty performance.
