Peer-Reviewed Literature & Technical Research
Design decisions are grounded in peer-reviewed research spanning ergonomic apparel design, advanced textile technologies, and occupational health studies.
Key Finding: Specialized apparel reduces injury risk in physically demanding occupations through ergonomic pattern design and strategic reinforcement placement.
Relevance to Capstone: Military personnel and field archaeologists share similar physical demands—both require constant crouching, kneeling, and repetitive movements. This research validates the articulated knee design and high-waist construction approach.
Articulated knee construction with 15-20° forward angle and strategic reinforcement at high-stress zones directly applies military ergonomic principles to archaeological fieldwork.
Key Finding: Balance between protection and breathability is critical for outdoor worker performance. Waterproof garments that trap heat lead to reduced work capacity.
Relevance to Capstone: With 93% of survey respondents working 7+ hours outdoors daily and 86% reporting frequent weather impact, breathability is essential. This justifies Gore-Tex Pro 3-layer selection (RET <6).
Gore-Tex Pro N40r-X (RET <6) for torso/arms provides optimal moisture-vapor transmission. Schoeller c_change 4-way stretch enhances breathability during excavation.
Key Finding: Nanocomposite coatings increase abrasion resistance by 30-50% compared to traditional textile treatments, extending garment lifespan.
Relevance to Capstone: Survey respondents identified durability as the highest-priority attribute (4.71/5.0) with the largest satisfaction gap (-1.64). This validates material selection combining traditional waxed cotton with advanced membranes.
Double-layer Halley Stevensons 8oz waxed cotton at knees/seat provides traditional abrasion resistance. Gore-Tex Pro N80p-X combines modern membrane technology with 100,000+ Martindale cycles durability.
Key Finding: Hydrophilic polyurethane membranes offer waterproof-breathable performance without PFAS chemistry, addressing environmental concerns while maintaining technical standards.
Relevance to Capstone: Validates feasibility of transitioning from ePTFE (PFAS-containing) to ePE (PFAS-free) membranes for future production, supporting sustainability goals.
Gore-Tex ePE membrane (PFAS-free, 30% lower carbon footprint) represents the planned material transition path, maintaining 28,000mm waterproof rating and RET <6 breathability.
Key Finding: Anthropometric integration with movement analysis enables task-specific apparel design. Garments designed for specific occupational movements significantly outperform generic alternatives.
Relevance to Capstone: Validates the research methodology—conducting user surveys to identify specific movement patterns (93% constant/frequent crouching), then designing articulation accordingly.
Survey data on physical demands directly informs pattern articulation angles (15-20° knee), waist rise specifications (26.5cm front, 32-34cm back), and pocket placement optimization.
User Research Findings (n=14)
Key Research Insight
93% of CRM archaeologists crouch/kneel constantly or frequently during fieldwork
yet existing field apparel shows significant satisfaction gaps in mobility (-1.50), durability (-1.64), and tool access (-1.64). This quantitative evidence directly informs the articulated knee design, reinforced high-wear zones, and optimized pocket system in the capstone project.

Gore-Tex Pro: ePTFE vs ePE Membrane Comparison
Gore-Tex Pro is available in two membrane technologies: traditional ePTFE (expanded PTFE, contains PFAS) and newer ePE (expanded Polyethylene, PFAS-free). Performance equivalence enables environmentally responsible material selection.
| Performance Metric | ePTFE (PFAS) | ePE (PFAS-Free) |
|---|---|---|
| Membrane Technology | Expanded PTFE | Expanded Polyethylene |
| Waterproof Rating | 28,000mm hydrostatic head | 28,000mm hydrostatic head |
| Breathability | RET <6 (excellent) | RET <6 (excellent) |
| Abrasion Resistance | 100,000+ Martindale cycles | 100,000+ Martindale cycles |
| PFAS Status | Contains PFAS | PFAS-Free |
| Carbon Footprint | Higher (baseline) | 30% lower than ePTFE |
| Commercial Availability | Industry standard (phasing out) | Commercial since 2022-2024 |
Performance Equivalence
- →Identical waterproof rating (28,000mm)
- →Identical breathability (RET <6)
- →Equivalent abrasion resistance (100,000+ cycles)
- →Same construction methods (3-layer laminate)
Environmental Benefits (ePE)
- →30% lower carbon footprint vs ePTFE
- →No PFAS bioaccumulation in environment
- →No long-term persistence concerns
- →Reduced water contamination risk
Regulatory Landscape
- →EU PFAS ban: Effective winter 2025/26
- →US state-level restrictions increasing
- →Industry voluntary phase-out commitments
- →Gore-Tex Pro ePE widely available
Recommendation: Transition to ePE
While the prototype may initially use ePTFE for cost/availability reasons, commercial production should transition to Gore-Tex Pro ePE for the following reasons:
- →Performance parity: No technical compromise—identical waterproof/breathable specs
- →Environmental responsibility: 30% carbon reduction + elimination of persistent chemicals
- →Regulatory compliance: Future-proof against PFAS restrictions
- →Market positioning: Aligns with professional archaeologists' environmental values
- →Long-term viability: ePTFE phase-out timeline accelerating industry-wide
Personal Reflections
Chronological journal entries documenting learning progression, challenges encountered, and insights gained throughout the technical apparel production course.
Understanding Waterproof Construction
Learning about seam sealing techniques revealed why every stitch creates a potential leak point. This understanding directly informed my approach to the capstone pants design, where I specified fully taped seams and waterproof zippers with gaskets.
Articulation Design Challenge
The challenge of designiing for movement while maintaining waterproof integrity led to innovative solutions. Articulated knees require careful pattern work to avoid excess fabric bunching while allowing full range of motion during fieldwork.
Material Selection and Sustainability
Researching Gore-Tex Pro vs ePE alternatives highlighted the industry tension between performance and environmental responsibility. While ePE offers PFAS-free benefits with lower carbon footprint, Gore-Tex Pro remains the performance standard. For commercial viability, transitioning to ePE would be ideal.
Fit Session Insights
Conducting fit sessions on the prototype revealed the importance of high-waist construction for fieldwork applications. The additional coverage prevents debris entry and provides core support during physically demanding activities.
Production Methodology Integration
Connecting technical production knowledge to business viability has been enlightening. Understanding manufacturing complexity, 58+ pieces and 5+ hours assembly time for technical outerweear, directly impacts pricing strategy and target market positioning.
Industry Insights & Future Direction
This course has transformed my understanding of technical apparel production from design concept to manufactured reality. The complexity of waterproof construction, the precision required in spec development, and the careful balance between performance and sustainability have all become clear. The technical apparel industry is at an inflection point performance standards remain high, but environmental consciousness is driving material innovation. My capstone project embodies this tension: specified with Gore-Tex Pro for proven performance, but researched with ePE alternatives in mind for future sustainability goals. The skills developed in pattern articulation, fit methodology, and construction sequencing will be foundational as I move into professional practice. The challenge ahead is maintaining technical excellence while pioneering more sustainable production methods.
