Arbo Space Full Metal SRT Chest Harness | All-Aluminum, No Plastic

Arbo Space Full Metal SRT Chest Harness — Zero Plastic. All Aluminum.

Most chest harnesses have a weak point: plastic. Plastic buckles crack in the cold, degrade in the sun, and snap when your gear gets dropped, dragged, or stepped on. So we removed it entirely.

The Arbo Space Full Metal SRT Chest Harness is built with 100% aluminum hardware. Where other harnesses use plastic side-release buckles, we use twin aluminum mini carabiners on each side — fast to clip, easy to operate with gloves, and built to take the abuse of daily production climbing. Even the adjustment hardware is aluminum, so every load-bearing and adjustment point on this harness is metal.

Designed for SRT (stationary rope technique) climbing, the harness keeps your chest ascender or rope wrench tether positioned high and centered via the aluminum ring at the sternum, improving your posture and efficiency on ascent. The elasticated center strap moves with you, while the Y-back webbing design distributes load comfortably without restricting shoulder movement.

Why climbers choose it:

• Zero plastic construction — every buckle, adjuster, and connection point is aluminum
• Mini carabiner closures — quick on/off, glove-friendly, no brittle clips to break
• Aluminum sternum ring — clean, centered attachment for your SRT ascent system
• Fully adjustable — aluminum sliders on the shoulder and chest straps dial in your fit
• Lightweight nylon webbing — durable, low bulk, all-day comfort

Whether you're on a big removal or a long access line, this is the chest harness that won't let a two-dollar plastic buckle end your workday.

Note: This chest harness is a positioning accessory for SRT ascent and is intended for use with a certified sit/work-positioning harness. It is not a standalone fall-arrest device.
