Leather Sunglasses Strap

It is a little long and I wish it flapped down a little but when I wear it but I like it!

I Love it. I ordered for my grandson and he loves it.

I love the quality of the product. Any tips to get the leather to better fit my sunglasses? I have Raybans and wearing the straps while driving pushes them off my head when I lean against the head rest. Maybe this is because the leather is so new?
