Hardcap™ A1+ Bump Cap The new HardCap™ A1+ is another major innovation from JSP in head protection design. Designed to exceed the most recent standards, EN812:2012, years of thought and design iterations have been undertaken to develop a product that is unrivalled in both performance and style. Sleek and low profile, it’s almost impossible to distinguish from a standard 'high street' baseball cap. The unique angled adjuster designed to fit under the occipital bone at the rear of the skull means that one size really does fit all, particularly when combined with the castellated protective liner. The liner is removable, therefore the cap part is machine-washable for hygiene purposes. It has a terrytowelling sweatband for added comfort and all colour-ways have subtle reflective piping for added visibility safety.
