Petzl Attache

 Petzl Attache
The Petzl Attache used to be hands down the best compact belay carabiner but now it has some tough competition. The Metolius Element is cheaper and slightly lighter and smaller. We like the Attache more but if you are on a budget you might consider t...

Petzl Am'D

 Petzl Am'D

The Petzl Am'D is a versatile biner that stands out because it is a little bigger than most HMS belay biners but smaller than a typical monster locker. It has a great weight-to-versatility ratio, meaning you can do a lot with it but don't feel ...

Omega Pacific Jake

 Omega Pacific Jake
Omega Pacific's Jake is a solid belay, rappel and top rope carabiner. It is not perfect for multi-pitch or mountaineering if weight is a factor. For that we would go with something like the Petzl Attached 3D]J]. The Jake held multiple knots/slings be...
