Not a big deal, but I think the rubber should be able to handle a lot of distorting. I would honestly ask JPS about it. I bet anything they’d refund your order and replace it for free. Anyway, not the end of the world. I’d pay for one after maybe 4-5 years of heavy use, but I’d expect warranty in less than one year on something like this.
Actually, a split rubber band design with a couple of knots on the end to prevent slipping past the metal clasp would work just fine as a fix without replacing the whole headband. Seems like an idea to consider for JPS.
Yea I'm not too fussed about it. I think Abyss/Joe do read this thread so if they decide to get in touch then great, but if not then it's ok.
