The KIWI design Comfort Battery Head Strap for the Quest 3 is the ultimate VR battery head strap for extended gaming sessions. Its 6400mAh batteries pump life into your VR experience, adding an additional 2-4 hours of gameplay. Its thick cushions on the top and back, made with soft PCU leather and memory foam improve comfort and reduce pressure around your head, allowing you to explore in VR safely and in comfort. We loved that the side strap is eco-friendly and is proven to endure up to 10,000 bends for a design that promises maximum durability. Accommodating a wide range of head sizes from 17.7-29.5 inches, the enlarged bracket comfortably holds your head and ensures an easy fit for extended wear.
