Peak Design AL-4 Anchor Links

Excellent piece of product design, serves the purpose it was designed for very well.
A small anecdote will illustrate the matter even better, after fitting my regular camera strap with the al4 links I had put it in my backpack separately. The other half of the links were on my camera. Recently while going on a trip I picked up my camera bag forgetting that the camera strap was not attached, but because the al4 loops were attached to the camera, I could use the shoulder strap of the camera bag as a replacement for the camera strap.

This is a must item to have always attached with your camera
