Was tempted to lie just to support a small local business but although I like the hub system, this particular pouch design is kinda… thoughtless.
It’s a material bag. A fixed width. Open top. Non elasticised. No toggle. Nothing to grip or secure the glasses inside the pouch except a wish and a prayer.
So. Let’s say you attached this pouch onto a the side of a backpack, and then you bend down to tie a shoelace. GOODBYE GLASSES and hello scratched lenses. If you are lucky to have the right sized glasses (I.e. not too oversized, as per some reviewers, and not too slimline like most of mine) it’s probably fine.
Attached is a video of my largest glasses: medium sized Dresden frames.
