The Synth has the option of an integrated seat harness connection, from full waist harness to a fully supported seat harness. This does not interfere with the harnesses primary all-round waist harness functionality.

Constructed with low profile pressed aluminum webbing buckles to reduce hard points and thick material bunching, which often cause unnecessary discomfort. The Synth features a full neoprene interior and after testing many internal moldings we determined the full neoprene interior had the best all-round performance and was the most comfortable with and without a wetsuit.
