I've bought the carabiner on my keychain to attach it to the pants can. Although I was initially a bit skeptical because of the small size of the carabiner, I am very satisfied. The slightly smaller size affects even positive, since the carabiner thus not so bulky. At least with my pants all the belt loops fit easily into the carbine, also slightly wider loops should not be a problem. The workmanship is very good, so I can recommend this without reservation.
