Rider reviews
What riders say about the V501
Answers
Frequently asked questions
What type of rider is the V501 best suited for?
The V501 is ideal for commuters, tourers, and everyday riders who face regular cold weather and prefer a lightweight, sleeveless design. It offers a reliable, balanced level of warmth that makes it a perfect all-rounder for typical UK and European winter conditions.
Is the V501 waterproof or windproof on its own?
No, the V501 is designed as a mid layer and should be worn under a protective outer jacket that offers waterproofing and abrasion resistance. However, the vest fabric is wind resistant, breathable and heat retentive, helping to trap warmth effectively under your outer shell.
How does the V501 compare to the J501 in terms of heat output?
The V501 provides excellent warmth, delivering the same core power as the J501. As it does not include the sleeves, the overall output is smaller, therefore it is better suited for moderate cold weather riding, offering comfort and coverage with dual use both on and off the bike when paired with the KEIS 5000mAh portable battery.
Where are the heating panels located in the V501?
The V501 features Far Infrared heating panels in the chest and back. This keeps your core temperature up while using less power than the J501, which adds heating panels in the sleeves and collar.
What power sources can be used with the V501?
The V501 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 vest without needing to connect to the bike.
Can I connect other heated garments to the V501?
Yes, the vest includes a central power hub that lets you connect other KEIS garments, such as gloves or trousers. This allows multiple garments to be powered and controlled together, simplifying setup and keeping your gear streamlined.
