Product Details
The Oxford ATMOS Heatcore Base Layer Trousers in Black are unisex thermal motorcycle leggings for colder rides. Hypoallergenic, fleece-backed ThermoBoost™ fabric is strategically knitted to retain heat while moving moisture away from the skin, providing targeted warmth without excessive bulk beneath protective trousers.

Thermoregulatory yarn supports moisture transfer as conditions and activity levels change. The slim fit keeps the insulating fabric close to the body, while flatlock seams maintain a smooth, low-profile feel under riding kit.

Questions and answers
Are these the warmer ATMOS trousers?
Yes. Heatcore uses fleece-backed ThermoBoost™ fabric for additional insulation. The ATMOS Core trousers are the lighter all-season alternative.
Can they be combined with other ATMOS layers?
Yes. Oxford designed the ATMOS system so riders can combine base and mid-layers according to the weather and journey.
