TERRA FIRMA FORTIS FLETCHED ARROWS - 350 SPINE

Description

When it’s all on the line, shoot with confidence — choose the FORTIS.

The FORTIS 4mm is Terra Firma’s original arrow, tested and proven over more than a decade of successful hunts. Built for serious bowhunters, this shaft delivers a clean balance of speed, precision, and toughness.

Its slim 4mm profile and dense carbon build give it a deadly combo of penetration and stability. Paired with the 60gr alloy outsert system, the FORTIS holds a high FOC for a heavyweight arrow, giving you powerful flight and consistent hits—even when smashing through bone.

This is the arrow that made the Terra Firma name. Reliable. Efficient. Ready for anything.
