Nikon’s new Trex modular optic carry systems are headed for dealers’ shelves and, with hunting seasons approaching, available for the serious outdoors enthusiast.

The Trex harness comfortably distributes an optic’s weight during long miles in the field and is available in three system variants – FreeStyle, EXO and 360 – designed to address the degree of optics protection sought for your environment.

All components in the system are fully interchangeable, allowing users to modify the Trex into any of the above variants by adding or removing the optic accessory bags. Each model also has a ventilated yoke built into the harness that integrates a stowaway hydration net to allow you to accommodate your own hydration bladder.

At the system’s core is the Trex FreeStyle fully adjustable harness with quick-release attachment cords. This feature-packed harness securely holds your optic close to the chest while running or crawling, yet allows fast access for glassing.

TheTrex EXO carry system integrates a lightweight exoskeleton shell that provides incredibly fast access. In conjunction with the harness’s quick-release attachment cords that hold the optic securely in place, EXO offers protection of the eyepiece lenses even when the over-flap is not secured. Rear cellphone pocket has built-in microfiber cleaning cloth for keeping lenses smudge-free.

Nikon’sTrex 360 adds a water-resistant, padded optic compartment to shield and secure your glass while also keeping it at-the-ready. The patent-pending closure system keeps the case closed tight to shield against water, snow and dirt. Interior cellphone pocket has a built-in microfiber cleaning cloth. Molle webbing system on the front allows attachment of other gear, while a hand warmer pocket offers a compartment for a disposable pocket warmer.

MSRP is $40 to $120 for the five styles.
