The DMM Freedom Revo Leash is a high spec leash giving you the freedom of leash-less climbing without the worry of dropping your tools.

The Freedom Revo features clip in point half way up the leash, meaning if you do fall but your axes hold you can clip a sling into the leash and pull back up to your axes. A useful (but hopefully redundant) feature!  However, this item is only intended to prevent you from dropping your tools - at no point should you rely on it to provide security.
