Style Notes
The Jamie Long Trousers are part of the ALL SEASON collection and are 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.
Jamie long trousers are perfect for wearing underneath motorcycle trousers and perform just as well when worn as casual sports pants when not riding.
A unisex cut in black with contrasting grey marl pocket, with soft velour binding around the pocket. Soft elasticated waist and cuffs.
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 both the pocket and cuff.

Opted for the jamie baselayer trousers
with running shorts on top. Excellent choice due to the weather conditions once I got out onto the ridge heading up from sleet to the rocky part of Grisedale
pike. The rain started, I thought here we go 'wet n cold' I thought these trousers will start dropping off my waist but the drawstring provd me wrong. Heading off the summit across Hobcarton and down into the forest of Whinlatter. I thought the cold would start to set in but to my surprise I was lovely and warm. I can't wait until winter to put these trousers to the test again and all the other baselayer products. Once again to Planet-Knox for an excellent product
