The problem
Your Nalgene is nearly indestructible. Its loop is not.
The loop on your Nalgene keeps the lid attached. That's all it was built to do. Hang a liter of water from it and it stretches, then snaps. On a sidewalk that's a scuff. On a river it's a lost bottle.

Why metal
Aluminum, not plastic.
A powder-coated aluminum ring with 1-inch webbing, bar-tacked. It carries the bottle so the loop doesn't have to.
