The Halcyon Mark 8 Service's design incorporates silver painted solid brass frames into a soft brown synthetic leather facemask through hand-stitching. It has a sliding nose bridge which allows the size of the goggle to be adjusted for individual comfort. The angled lenses are made from 99% UV-protected polycarbonate which is treated with a scratch-resistant coating. Each lens is housed in an independent frame which can be easily removed from the goggle to allow replacements to be fitted.
The head band now also comes fitted with triple silicon, elasticated non-slip strips for the perfect grip when worn over an open face crash helmet.
