ZÆD is an adjustable belay resistor that allows lightweight climbers to belay their heavier climbing partner. It allows for soft belaying - our testers say ZÆD feels like belaying / being belayed by a climber of the same weight. Now you can enjoy sports climbing with soft belays, regardless of the weight difference.



Soft Belay


The table shows the maximum recommended weight difference for a safe and soft belay during a sports climb without and with ZÆD at its different friction levels. The adjustability makes ZÆD your perfect companion even for changing climbing partners with different weight.

TÜV tested

There's no CE / EN / UIAA standard for belay resistors yet. That's why we decided to have ZÆD tested by TÜV Austria after the strictest standards.
