Which VRCover did you buy specifically for sweat? I bought the memory foam soft cotton one (it's supposed to come in tomorrow" because I wanted to to be washable, but also comfortable in other scenarios, though I very much have the same experience as you described and I'd like to make exercising with VR games a much bigger part of my routine.
Edit: I'm mostly curious about the "leather" ones as they sounded uncomfortable for other usage, but specifically aimed at physical exertion.
I bought this one but I'm not totally happy with it. For now it does the job but I'm sure better options will come out at some point hopefully sooner than later:
Ohhh, I actually bought one of the replacement foams. Here were the two I was considering, I bought the first of the two I linked and will be getting it tomorrow.
I am looking for a cover that does not soak up the sweat? I like to take the vr to family parties with dozens of people trying the device and the nasty factor can be really if used heavily. I am looking for something that can be wiped with alcohol between uses.
