The JAMMY self-locking sling made of aramid and polyamide offers a very high resistance, even in case of strong heating. Thanks to the Technora aramid technology, it does not suffer from being repeatedly folded and remains flexible and able to grip even small diameter ropes. Its seam is protected by a heat-shrinkable sheath and the material used makes it unmatched in lightness compared to mechanical systems.

The characteristics of the JAMMY sling make it a must have, especially when making self-locking knots to secure rappelling. But also to make a rope clamp for quick hauling. We recommend its use with Prusik and Machard knots.
