The Petzl Attache 3D is a new version of the Petzl Attache carabiner which is 31 percent lighter than the original. I will use this carabiner mainly to attach stuff to my backpack which I consider quite handy especially after my last trip to Sarek.
The Petzl Attache 3D is 55 grams light, has a barrel lock and a good design.
I have not tried the carabiner for climbing so I am not able to say anything about it’s climbing properties. It’s a little bit expensive compared to other carabiners but I like the weight, look and that the gate barrel can be locked. I use it mainly to attach different gear on my backpack and packraft.
