Abigail ★★★★★ Sep 15, 2026

The hollow-braid construction really does bite harder than the nylon cord I used before, especially on wet ropes where my old setup kept slipping. Tied it as an autoblock and it grabs with barely any wraps.

Zoe ★★★★★ Sep 14, 2026

Swapped this onto my prusik loop and the difference in bite is obvious, it grabs almost instantly without me having to wrap it an extra time. The hollow-braid construction really does seem to hold better on a wet rope than the standard cord I used before.

Gripped way harder than the nylon cord I was using before, even on a wet rope. The hollow braid feels stiff at first but it bites instantly when you weight it. Tied a prusik with it and it held without any slipping.
