Body Risk Mapping & Protection Zoning Standard
The CPG Body Risk Mapping System™ (BRM™) is a proprietary body-mapped protection framework developed for the ChisuProGuard™ Protective Sportswear Technology Platform.
BRM™ divides the human body into defined protection zones according to injury exposure, cutting risk, movement requirements, anatomical location, sport-specific dynamics, and garment construction.
The system enables ChisuSport to determine where protection is required, how much protection is required, and how protection should be integrated into the garment.
Protect Where Needed. Move Without Restriction. Perform Without Compromise.
1. BRM™ Protection Zone Architecture
The CPG Body Risk Mapping System™ consists of five primary protection zones:
| Zone | Classification | Protection Priority | Typical Application |
|---|---|---|---|
| Z0 | Mobility Zone | Movement Priority | Underarm, groin, popliteal area, major flexion zones |
| Z1 | Low-Risk Zone | Basic | Low-exposure body areas |
| Z2 | Medium-Risk Zone | Moderate | Areas with occasional exposure |
| Z3 | High-Risk Zone | High | Areas with significant cutting/contact exposure |
| Z4 | Critical Protection Zone | Maximum | Anatomical areas requiring the highest protection priority |
The five zones do not represent a single standardized laboratory protection level. They represent ChisuSport’s internal body-risk classification framework used to guide material selection, garment construction and protection engineering.
2. Z0 — Mobility Zone
Mobility Priority Zone
Z0 represents anatomical areas where maximum freedom of movement, flexibility, and biomechanical efficiency are required.
Typical areas include:
- Underarm
- Groin
- Hip Flexion Zone
- Popliteal Area
- Elbow Flexion Area
- Knee Flexion Area
- Other high-mobility anatomical regions
Engineering Principle
Protection should not unnecessarily restrict:
- Joint articulation
- Muscle expansion
- Flexion and extension
- Stride length
- Hip rotation
- Aerodynamic body positioning
Recommended Construction
High-Stretch Performance Fabric
or
Ultra-Lightweight Cut-Resistant Construction
or
Strategically Reduced Protection Coverage
Primary Objective
Maximum Mobility × Minimum Restriction
Z0 is not defined as an unprotected area. Protection may be incorporated when required by the sport-specific risk assessment.
3. Z1 — Low-Risk Zone
Basic Protection Zone
Z1 represents body areas with relatively low exposure to direct cutting or high-energy contact hazards.
Typical characteristics include:
- Low probability of direct blade contact
- Low injury exposure
- Limited requirement for reinforced construction
Recommended Construction
- Performance Fabric
- Stretch Fabric
- Lightweight Cut-Resistant Fabric
- Single-Layer Protection
Primary Objective
Lightweight Construction × Functional Coverage
Z1 allows ChisuSport to minimize unnecessary weight and maintain overall garment comfort.
4. Z2 — Medium-Risk Zone
Enhanced Protection Zone
Z2 represents areas with a moderate probability of exposure to cutting, abrasion, contact, or equipment-related hazards.
Typical areas may include:
- Forearm
- Upper Arm
- Thigh
- Lower Leg
- Shoulder
- Side Torso
Recommended Construction
Cut-Resistant Fabric
or
Performance Fabric + Cut-Resistant Liner
or
Single-Layer Zoned Protection
Primary Objective
Balanced Protection × Mobility × Comfort
Z2 is commonly used for performance garments where protection must be integrated without significantly increasing garment weight or reducing flexibility.
5. Z3 — High-Risk Zone
High Protection Priority Zone
Z3 represents anatomical areas with significant exposure to cutting, impact, equipment contact, or sport-specific injury mechanisms.
Typical applications may include:
- Neck
- Forearm
- Wrist
- Upper Thigh
- Shin
- Knee
- Other sport-specific high-risk regions
Recommended Construction
High-Performance Cut-Resistant Fabric
or
Performance Fabric + Cut-Resistant Liner
or
Double-Layer Cut-Resistant Construction
Primary Objective
High Protection × Controlled Mobility
Z3 protection should be engineered according to the specific sport, garment architecture and movement requirements.
6. Z4 — Critical Protection Zone
Maximum Protection Priority Zone
Z4 represents body areas where protection receives the highest engineering priority because of the potential severity of injury and/or high exposure to sport-specific hazards.
The specific Z4 locations shall be determined through a Sport-Specific Risk Assessment.
Potential applications may include:
- Critical blade-exposure areas
- High-risk vascular regions
- High-energy contact zones
- Sport-specific impact or cutting zones
Recommended Construction
Multi-Layer Cut Protection
or
Double-Layer / Composite Protection
or
Cut + Impact Integrated Protection
or
Modular Protection Insert
Primary Objective
Maximum Practical Protection × Controlled Performance
Z4 protection must not be assigned solely based on anatomical location. It should be established through documented sport-specific risk analysis.
7. BRM™ Protection Matrix
The BRM™ framework can be integrated with ChisuProGuard™ protection levels.
| Body Zone | Risk | Protection Priority | Typical Construction |
|---|---|---|---|
| Z0 | Mobility Critical | Mobility | Stretch / Lightweight Protection |
| Z1 | Low | Basic | Performance Fabric / Single Layer |
| Z2 | Medium | Moderate | Cut Fabric / Cut Liner |
| Z3 | High | High | High-Performance Cut Protection |
| Z4 | Critical | Maximum | Multi-Layer / Composite / Insert |
This matrix provides a common language for design engineering, material selection, pattern development, prototyping and testing.
8. BRM™ × ChisuProGuard™ Architecture
BRM™ functions as the body-mapping layer beneath the five ChisuProGuard™ architectures.
PGF — ProGuard Full
Whole-Garment Protection
BRM™ determines where different protection constructions may be optimized within a full-garment platform.
PGP — ProGuard Partial
Targeted Protection
Protection is concentrated primarily in Z2, Z3 and selected Z4 areas.
Z0 and Z1 may use lightweight performance construction where appropriate.
PGZ — ProGuard Zoned
Body-Mapped Protection
PGZ is the primary architecture directly driven by the BRM™ system.
Example:
Z0 → Mobility Fabric
Z1 → Performance Fabric
Z2 → Cut-Resistant Fabric
Z3 → High-Performance Cut Protection
Z4 → Double-Layer / Composite Protection
PGI — ProGuard Insert
Modular Protection
BRM™ determines the location and priority of removable protective components.
Examples:
- Z3 → Cut Insert
- Z4 → Advanced Cut Insert
- Z3/Z4 → Cut + Impact Insert
PGA — ProGuard Aero
Protection × Aerodynamics
BRM™ is combined with aerodynamic zoning to determine where protection can be integrated without unnecessarily increasing:
- Surface disruption
- Garment thickness
- Seam complexity
- Drag-generating structures
- Movement restriction
This creates a three-dimensional engineering relationship:
Body Risk × Protection × Aerodynamics
9. BRM™ Engineering Logic
The BRM™ system follows a five-step engineering process:
Step 1 — Risk Identification
Identify potential injury mechanisms based on:
- Sport
- Equipment
- Blade exposure
- Contact mechanics
- Fall dynamics
- Body position
- Competition environment
Step 2 — Body Mapping
Map identified hazards onto anatomical regions.
Step 3 — Risk Classification
Assign each region a BRM™ zone:
Z0 → Z1 → Z2 → Z3 → Z4
Step 4 — Protection Engineering
Select:
- Material
- Layer configuration
- Protection level
- Seam construction
- Pattern geometry
- Insert architecture
Step 5 — Validation
Validate the final garment through:
Material Testing → Component Testing → Garment Testing → Sport-Specific Validation
10. BRM™ Dynamic Mapping
BRM™ should not be considered a static anatomical map.
During high-performance sports, body position changes continuously.
Therefore:
BRM™ is a dynamic body-risk mapping system rather than a simple anatomical protection chart.
The same anatomical area may experience different risk levels depending on:
- Body position
- Joint angle
- Movement direction
- Sport-specific technique
- Equipment interaction
- Speed
- Impact trajectory
This principle is particularly important for:
Speed Skating
Ice Hockey
Ski Racing
Kart Racing
and other high-speed sports.
11. BRM™ Design Principle
The fundamental philosophy of the CPG Body Risk Mapping System™ is:
Not More Protection Everywhere.
More Protection Where It Matters.
Protection should be concentrated where risk is highest while preserving mobility, comfort, weight efficiency and athletic performance in lower-risk regions.
This enables ChisuSport to move from traditional:
Uniform Protection
to:
Body-Mapped Protection
and ultimately toward:
Sport-Specific Intelligent Protection Engineering.
