Sparco Delta RW-6 open face balaclava with external seams. The latest development from Sparco, with two layers of fire resistant Nomex, with flat internal seams and one large open eye hole design for maximum visibilty and comfort. Natural Nomex finish only.Sparco Delta RW-6 long sleeve top and long johns. Both created using the 'body-size' syle of manufacturing, where the main body of the garment is produced from a single piece of fabric, without any side seams or stitching. Other sections of the garment are made from fabrics with differing elasticity, to ensure the garment fits and feels and comfortable as possible. These garments also use two different types of fabric design in terms of breathability and are also employed where required for the the best driver comfort, with their seams being positioned to ensure they are least detected by the wearer.
