Kratos FLY'IN 1 Extra-Comfort Body Harness - 2 Attachment Points and Textile Chest Loops

Kratos FLY'IN 1 Extra-Comfort Body Harness

The Kratos FLY'IN 1 is a premium 2-point full body harness designed for intensive use by construction operatives, scaffolders, steel erectors, and maintenance engineers who wear a harness throughout a full working shift in physically demanding conditions. The cushioned mesh net back panel is the defining feature of the FLY'IN 1 range. It replaces the solid webbing back panel found on standard harnesses with a breathable mesh net construction that distributes contact pressure across a wider area of the back, reduces heat build-up during sustained wear, and provides a degree of shock absorption during active movement that standard webbing cannot offer.

The chest attachment uses two textile loops rather than a metal sternal D-ring. These are rated A/2 as a secondary fall arrest attachment point under EN 361:2002 and are suited to aerial lift applications, cherry picker operations, and scenarios where a frontal connection point is required alongside the primary dorsal D-ring. Aluminium buckles throughout keep the overall harness weight down. Two tool holder loops at the rear allow karabiners and accessories to be carried on the harness rather than in a separate pouch.

Why Choose the Kratos FLY'IN 1 Extra-Comfort Body Harness

• Cushioned mesh net back panel: the mesh net construction distributes the contact pressure of the harness across the full back rather than concentrating it on the narrow webbing lines of a standard harness. During intensive use where the harness is worn for a full shift, this reduces fatigue and discomfort directly, which in practice means the harness stays correctly adjusted throughout the day.

• Textile chest loops rated A/2: two correctly positioned textile loops provide the frontal attachment point for applications where a sternal connection is required. Textile loops are lighter and lower-profile than a metal sternal D-ring, which is why they are specified on premium intensive-use harnesses where total weight and bulk across a full shift matters.

• Aluminium buckles throughout: aluminium construction across all buckles reduces the total harness weight compared to steel buckle equivalents, making a meaningful difference over a full working shift in intensive use conditions.

• Combination buckles on shoulder straps: provide secure downward-direction adjustment that resists accidental release during upward arm movements, which is the correct buckle type for shoulder straps on a harness rated for intensive use.

• 2 tool holder loops at rear: allow karabiners, accessories, and short lanyards to be carried directly on the harness, keeping the operative's hands free and reducing the need for additional tool-holding equipment.

• Intensive use rated: Kratos classifies the FLY'IN 1 in the Premium range and rates it for intensive use, the highest frequency category in the Kratos selection guide. This is the correct specification for operatives who wear a harness every working day in demanding site conditions.

Compatibility

Who Is This For?

Construction operatives, scaffolders, steel erectors, and maintenance engineers who wear a harness throughout a full working shift in intensive use conditions and need the highest level of comfort available within the EN 361 full body harness category. Also specified for aerial lift and cherry picker operators where a chest attachment point alongside the dorsal D-ring is a requirement. Chosen by safety managers equipping operatives who have experienced discomfort and fatigue from standard harnesses during intensive daily use.

Typical Applications

• Full-shift scaffolding erection and dismantling in intensive use conditions

• Structural steelwork installation requiring sustained harness wear across a working day

• Aerial lift and cherry picker operations requiring both dorsal and chest attachment

• Inclined plane and horizontal surface work requiring full body harness protection

• Fixed ladder and lattice metallic structure access

• Any intensive use application where standard harness comfort is insufficient for the working pattern

How frequently do I use my harness?

How to Use

1. Check all webbing for cuts, abrasion, and contamination before donning. Inspect the mesh net back panel, both textile chest loops, and the dorsal D-ring.

2. Hold the harness by the dorsal D-ring and shake out to confirm no straps are twisted.

3. Slip on the shoulder straps. The mesh net back panel should sit flat against the upper back.

4. Connect the chest strap automatic buckle across the sternum. Adjust so the textile loops sit correctly on the chest.

5. Pull each thigh strap under the leg and connect the automatic buckle. Confirm both are locked.

6. Adjust shoulder combination buckles so the dorsal D-ring sits between the shoulder blades. Thread free lanyards through the web keepers on the shoulder straps.

7. Connect the fall arrest device to the appropriate attachment point before approaching the fall risk area.

Safety and Maintenance

Before every use:

• Inspect all webbing for cuts, abrasion, chemical staining, and UV degradation

• Check both textile chest loops for cuts, rigidity, wear, and distortion

• Confirm the dorsal D-ring is free from deformation and corrosion

• Check all aluminium buckles open, close, and lock correctly

• Inspect the mesh net back panel and confirm it is not damaged in a way that affects harness function

During use:

• Connect fall arrest device only to the dorsal D-ring or textile chest loops as appropriate to the application and device manufacturer's instructions

• Never use as a work positioning device without a separate EN 358 belt

• Do not exceed 140kg total user weight including all tools and equipment

After use and storage:

• Clean with mild soap and warm water, dry naturally away from heat

• Store away from UV, chemicals, sharp objects, and heat sources

• Annual formal inspection by a competent person required under PUWER

• Withdraw from service immediately after any fall arrest event

Frequently Asked Questions

Q: What are the textile chest loops and how do they differ from a metal sternal D-ring?

 A: The textile chest loops are two webbing loops positioned on the chest strap, rated A/2 as a secondary fall arrest attachment point under EN 361:2002. Unlike a metal sternal D-ring, they are constructed from the same polyester webbing as the harness straps. They are lighter and lower-profile than a metal D-ring, which reduces total harness weight and bulk during intensive use. The A/2 rating means they function as a secondary attachment point, used alongside the primary dorsal D-ring rather than as an independent single-point connection for all applications.

Q: When should I use the chest loops rather than the dorsal D-ring?

 A: The chest loops are the correct connection point for certain aerial lift and cherry picker applications where the manufacturer's instructions specify a chest or sternal connection. They are also used in specific scenarios where a more upright post-fall suspension position is required. Always check the fall arrest device manufacturer's instructions to confirm which attachment point is correct for your specific combination of harness and device. For standard overhead fall arrest applications, the dorsal D-ring is the primary connection point.

Q: What does the cushioned mesh net back panel actually do?

 A: The mesh net replaces the solid webbing back panel of a standard harness with a breathable, cushioned construction that distributes the contact pressure of the harness across a wider area of the upper back. During intensive use where the harness is worn for a full shift, this reduces the pressure fatigue and discomfort that accumulates with a standard webbing back panel. The mesh also allows air circulation, reducing heat build-up during physical work. The practical result is that the harness remains comfortable to wear correctly adjusted throughout the day, which is why Kratos rates this for intensive use and classifies it in the Premium range.

Q: Why does this harness use aluminium buckles rather than steel?

A: Aluminium buckles reduce the total weight of the harness compared to steel buckle equivalents. For a harness worn intensively throughout a full working shift, the cumulative weight reduction across all buckles contributes to reduced fatigue. The aluminium used in Kratos buckles provides the necessary strength and durability for EN 361 fall arrest applications. If the harness will be used in environments where aluminium is not suitable, such as certain chemical or electrical environments, confirm compatibility before specifying.

Q: What is EN 361:2002 and what does it require from this harness?

 A: EN 361:2002 is the European standard for full body harnesses used as fall arrest equipment. It requires that all attachment points have a static strength above 15kN, that the harness holds the user in a safe position following a fall arrest, and that the maximum forward lean angle does not exceed 50 degrees post-fall. UKCA marking confirms this harness meets UK conformity requirements. Under the Work at Height Regulations 2005, all fall arrest harnesses used on UK construction sites must conform to the relevant standard.

Q: Is this harness suitable for operatives at the smaller end of the S-M size range?

 A: The S-M size covers a range of chest, waist, and height measurements. All straps are fully adjustable and the aluminium automatic buckles allow fine adjustment across the full range. The mesh net back panel and padded construction accommodate different body shapes within the size range. If an operative is consistently at the very lower end of the S-M range or is petite in build, confirm the adjustment range against the Kratos size guide before ordering.
