I love my Hiplok Original wearable chain.
It’s lightweight to the point where I sometimes have to check I’m still wearing it.
One thing to be aware of: Make sure you’ve pushed the locking clasp right in and to give it a tug to ensure it’s locked as it may appear lto be when it’s actually not.
Luckily when this happened to me, I was in a secure space so it wasn’t an issue but elsewhere…
All said and done, although somewhat pricey for the reflective model that I purchased, I would recommend this product.
