The Keis J601RP Ultraflex Heated Jacket is the most advanced heated mid-layer Keis has ever made. Engineered with UltraFlex 4-way stretch fabric, it delivers exceptional comfort, flexibility, and warmth in a slim, breathable design that fits perfectly under your motorcycle jacket. Lighter and thinner than the softshell J501RP and J505RP, it’s ideal when space is tight but warmth is non-negotiable.
Developed specifically for motorcycle riders, the UltraFlex material moves with your body, wicks away moisture, and maintains a snug fit without restricting movement. Inside, Micro Carbon Fibre heating panels deliver a powerful 65W of warmth across the chest, back, arms, and collar – keeping you warm from the moment you set off. The thumb holsters prevent sleeves from riding up as you gear up, and integrated power sockets in the cuffs and waistband allow connection to Keis heated gloves, trousers, socks or insoles, creating a fully connected heated system.
Supplied with a Keis Standard Power Controller (worth £36) and vehicle power lead, the J601RP is ready to plug in and ride straight out of the box.
