3M 1113001 DBI-SALA ExoFit X300 Comfort Vest Full Body Harness

The 3M 1113001 DBI-SALA ExoFit X300 Comfort Vest Full Body Harness is the premium tier of the 3M ExoFit fall arrest lineup — a single-D-ring vest-style harness engineered for workers who spend full extended shifts in the harness in facilities maintenance, manufacturing, and general industry elevated work environments. Scotchlite reflective material, aluminum hardware throughout, premium comfort padding beyond the X200 tier, and 420 lb capacity place the X300 at the top of the ExoFit comfort range. For workers whose elevated work exposure is high enough that harness comfort materially affects both safety compliance and physical productivity, the X300 is the correct specification.

For B2B procurement teams managing PPE programs for facilities operations, process industry maintenance, or any workforce with sustained elevated work exposure, the 1113001 delivers the highest comfort-per-hour specification in the ExoFit lineup at a premium that is justified by the fatigue reduction and compliance improvement in continuous-wear applications.

Specifications

Materials and Construction

The ExoFit X300 Comfort Vest 1113001 represents the highest comfort specification in the ExoFit series — a design refinement beyond the X200 padding tier that targets the specific pressure-point and fatigue patterns of workers who wear a harness for the majority of an extended work shift. The X300 padding system uses a more substantial cushioning structure at the shoulder straps and torso panel than the X200 tier, providing greater pressure distribution over a longer continuous wear period. For workers who are at height for four, six, or eight continuous hours — process maintenance technicians on elevated platforms, boiler and vessel workers, and large-scale facilities maintenance crews — the X300 comfort improvement versus lower tiers is perceptible over the course of a full shift.

Scotchlite reflective material is integrated into the harness construction in strips that provide retroreflective visibility under artificial light. In facilities environments where elevated work occurs in areas with uneven or directional lighting — manufacturing plants, warehouses, processing facilities, tunnel construction — Scotchlite reflective material allows workers at height to be more visible to ground-level coworkers, equipment operators, and supervisors. This is a safety benefit for the worker's visibility to others rather than the worker's own vision.

Aluminum hardware throughout — D-ring, all buckles, and adjusters — reduces the total harness weight compared to steel hardware alternatives and provides corrosion resistance appropriate for the humid, chemically active environments common in processing and industrial facilities. The aluminum D-ring is the standard dorsal passive design — fall arrest only, vest-style. Workers requiring the stand-up D-ring and anti-slide plate of the X200 platform should evaluate the ExoFit X200 Comfort Vest or X200 Construction Positioning models.

Compliance and Certifications

• ANSI/ASSP Z359.11 — Full Body Harnesses for Personal Fall Arrest Systems
• OSHA 29 CFR 1910.140 — General industry personal fall protection systems
• OSHA 29 CFR 1926.502(d) — Construction fall protection systems criteria

Real-World Benefits for Industrial and Facilities Operations

Compliance-sustaining comfort for full-shift elevated work. Harness discomfort is a documented behavioral driver of fall protection non-compliance. Workers who experience sustained shoulder or torso pressure during extended elevated shifts will adjust the harness to relieve pressure — reducing its protective effectiveness — or seek opportunities to remove it during brief ground-level activities. The X300's premium padding tier reduces this pressure-fatigue cycle, supporting correct harness fit and wear behavior over a full shift in ways that lower-comfort alternatives do not.

Visibility in low-light industrial environments. Scotchlite reflective material provides retroreflective visibility under work lights, flashlights, and equipment lighting in facilities environments where overhead or ambient lighting may be insufficient to make elevated workers visible to ground-level personnel. In environments where forklifts, cranes, or other mobile equipment operate in areas with elevated workers, improved worker visibility is a meaningful safety improvement.

Corrosion resistance for industrial environments. Aluminum hardware is more resistant to the corrosive effects of humidity, chemical vapors, and cleaning agents common in manufacturing and processing facilities than zinc-plated steel. For harnesses issued to workers in food processing, chemical manufacturing, water treatment, or other corrosive industrial environments, aluminum hardware maintains its rated performance over a longer service life without rust or corrosion-related degradation.

Applications and Use Cases

• Process industry elevated maintenance — chemical, refining, and manufacturing facilities where workers access elevated platforms, vessels, and equipment for maintenance and inspection
• Facilities management and operations — building maintenance teams in commercial and industrial facilities with regular elevated work requirements
• Manufacturing elevated work — production maintenance, machine work-at-height, and elevated equipment servicing in manufacturing environments
• Construction elevated work — OSHA 1926.502(d) compliant for construction site fall arrest where premium comfort is required
• Low-light and night work — any elevated application where Scotchlite reflectivity provides meaningful visibility to ground personnel

Compare: 3M 1113001 ExoFit X300 vs. Related Harnesses

vs. ExoFit X200 Comfort Vest 1402022 — The X200 Vest adds a stand-up aluminum dorsal D-ring and anti-slide plate that the X300 Vest does not include, at a lower cost. The X300 provides Scotchlite reflectivity and the premium X300 padding tier. Choose the X200 when the stand-up D-ring provides operational value for your anchorage connection frequency. Choose the X300 when maximum full-shift comfort and Scotchlite visibility are the priority and the standard passive D-ring is adequate for the application.

vs. ExoFit X100 Comfort Vest 1401001 — The X100 provides ExoFit fall arrest comfort at the entry price tier with steel hardware. The X300 delivers the premium padding, Scotchlite material, and aluminum hardware for workers with the highest sustained-wear requirements. Choose the X100 for standard fall arrest applications; choose the X300 for the highest-comfort specification in full-shift facilities and industrial applications.

Frequently Asked Questions

What is the weight capacity of the 3M DBI-SALA ExoFit X300 1113001?

The ExoFit X300 Comfort Vest 1113001 has a 420 lb weight capacity. This includes the combined weight of the worker plus all tools, equipment, and PPE worn or carried during use.

Does the ExoFit X300 have work positioning D-rings?

No. The 1113001 is a vest-style fall arrest harness with a single back dorsal D-ring. It does not include positioning-rated hip D-rings. Applications requiring work positioning compliance under ANSI Z359.2 must specify a harness with positioning D-rings, such as the ExoFit X100 Construction Positioning or X200 Construction Positioning.

What ANSI standard does the ExoFit X300 comply with?

The 3M DBI-SALA ExoFit X300 1113001 meets ANSI/ASSP Z359.11 for full body harnesses and complies with OSHA 29 CFR 1910.140 for general industry and OSHA 1926.502(d) for construction fall protection applications.

What makes the ExoFit X300 different from the X100 and X200?

The X300 is the premium comfort tier of the ExoFit lineup, adding Scotchlite reflective material and a higher-specification padding system compared to the X100 and X200. The X200 adds the stand-up D-ring and anti-slide plate that the X300 does not include — the X300 uses a standard passive dorsal D-ring and focuses the specification on maximum comfort and Scotchlite visibility rather than D-ring ergonomics.

Should I replace the ExoFit X300 after a fall?

Yes. ANSI Z359.11 requires all personal fall arrest harnesses to be removed from service and replaced immediately after any fall arrest event, regardless of visible damage to webbing, hardware, or padding. The fall arrest forces involved in an arrest event can cause internal structural damage that is not visible during inspection. Any harness known or suspected to have been involved in a fall event must be withdrawn from service before the worker returns to elevated work.

What is Scotchlite material on the ExoFit X300?

Scotchlite is 3M's retroreflective material technology. When light from a directed source — a flashlight, work light, or equipment lamp — strikes Scotchlite material, it reflects the light back toward the source with significantly higher intensity than standard fabrics. On the ExoFit X300, Scotchlite strips integrated into the harness make elevated workers more visible to ground-level personnel in low-light, directional-lighting, and dark industrial environments where overhead ambient lighting may be insufficient.
