Knox Jacob Baselayer


JACOB Long Sleeve Base Layer Shirt with a comfort fit –


The Jacob is part of the ALL SEASON collection and is carefully made in the Knox UK Factory in the Lake District.

Made from MerinoPerform™ Advantage and woven in Australia from luxuriously fine Merino wool, it is combined with cooling and fast-drying synthetic fibres in the fabric structure.  The mix of synthetic and Merino means that both vapour and sweat are managed away from the body keeping the wearer cool on hot spring/summer days and warm through the chill of autumn/winter.  Merino is some of the finest and softest wool of any sheep and has a silky outer layer, so it is comfortable to wear without itchiness and it has a natural resistance to the bacteria that causes odour.

The fabric’s natural properties and elasticity mean that the garments keep their shape and drape naturally, making them non cling, cool and comfortable.  The collection is ideal for motorcyclists as it has a high tensile strength as well as being highly breathable, fast wicking and drying


The Jacob has the richness of a grey marl body contrasting with light grey collar and cuffs on this long sleeve style.

Designed to be a comfortable non-cling fit, yet fine enough not to bunch up under outer clothing.  Offering a fashionable sports look with subtle branding on the neck and hem to make it perfect for wearing on and casually off the bike.
