Review on KIWI design Valve Index Head Strap Cover: Sweat-Resistant and Washable Accessory for Enhanced Comfort by Eric Pruett

While I can't say it's a 'must have' like some of KIWI Design's other Valve Index products, it's a very simple but effective solution to getting your Valve Index to keep clean and reduce wear and tear over time. The leather only covers the t-shirt material that comes with the index, which while comfortable, unfortunately absorbs sweat very easily, causes odor and wears out quickly. Leather is a great option because when it sweats you can just wipe it off without worrying that it will soak up the sweat and turn into a kind of "sponge". yes, it's as rude as it sounds. This product is also great when sharing a headset with multiple people, especially when your HMD could end up on some fatter/very sweaty heads. This allows for easy cleaning between users and keeps the main material of the headset in perfect shape. If you actively play VR with Valve Index I would say this is a great addition for you!
