What riders say about the B601
Answers
Frequently asked questions
Can I wear the B601 directly against my skin?
It’s recommended to wear the B601 over a base layer, such as a thin thermal or technical top. This helps distribute heat more effectively and provides a barrier between your skin and the heating panels, ensuring both comfort and optimal performance.
How is the B601 powered?
The B601 can be powered in two main ways. Using the supplied fused KEIS supply lead, it can connect directly to your motorcycle battery for unlimited power while riding. It can also be powered by a KEIS portable battery pack, sold separately, which is ideal for short trips or when off the bike and lets you power the bodywarmer without needing to connect to the bike.
What’s the difference between the B601 and a full heated jacket?
The B601 is a sleeveless version of the KEIS J601 ULTRAFLEX Heated Jacket. It offers all the same high performance core heating technologies, minus the heated sleeves. It's ideal for riders looking to reduce bulk or wear it as a true mid layer beneath a close fitting outer jacket.
How long does the B601 stay warm on battery power?
Run time depends on the battery you choose and the heat setting. Use the battery run time calculator on the product page for an estimate.
Can I connect other KEIS garments to the B601?
Yes! The B601 includes a central power hub that allows you to plug in other KEIS heated gear like gloves, trousers, or socks. This means you can power your entire heated clothing system from a single source, simplifying your setup.
Is the B601 waterproof?
While the B601 is made from breathable and durable materials, it is not waterproof and is designed to be worn underneath your protective motorcycle jacket. For best results, pair it with a waterproof outer layer when riding in wet conditions.
