How light can a sport climbing harness be? When developing the PRISMA, we wanted to push this question as far as possible. The result is a fully-fledged sport climbing harness with an impressive weight of just 168 g (size M)—less would be nigh-on impossible. Anyone obsessed with weight and counting every last gram will be unable to resist this harness. But a word of warning: if you still don't make the climb, there are no longer any excuses!
