What You Can Do

You can generate comprehensive technical design briefs that translate creative activewear concepts into precise manufacturing specifications. The skill details fabric composition, performance requirements (moisture management, stretch ratios, compression levels), construction methods, quality benchmarks, and testing protocols—giving manufacturers unambiguous guidance that reduces errors and accelerates production timelines.

Features

Fabric specification generator

specifies fiber content, weight, weave/knit structure, stretch percentages, and technical properties with measurable criteria

Performance requirements framework

defines moisture-wicking rates, compression ratios, recovery time, durability metrics, and activity-specific performance claims

Construction methodology

details seam types, thread specifications, closure systems, reinforcement areas, and assembly sequences for clarity

Testing standards mapper

prescribes relevant ASTM and ISO testing protocols (colorfastness, elasticity recovery, pilling resistance, shrinkage limits)

Size grading specifications

ensures consistent fit across size ranges with grade rules and tolerance windows

Quality checkpoint checklist

identifies critical control points during cutting, assembly, and finishing for first-article inspection

Cost and material impact analysis

highlights specification decisions affecting material costs and production feasibility

Manufacturer communication template

structures briefs in formats preferred by production partners to minimize interpretation gaps

Example Output

Example 1: High-Performance Running Legging Brief

  • Fabric: 88% nylon/12% spandex, 240 gsm, 4-way stretch knit with 150% elongation recovery
  • Moisture management: Capillary moisture transport ≥8 cm/30 min (ASTM F1868)
  • Compression: 18–22 mmHg graduated compression with 3mm rolled waistband
  • Seams: Flatlock construction on inseam; 3-thread safety stitch on waistband
  • Testing: Pilling (ASTM D3884 grade 4+), shrinkage (AATCC 96 <3%), colorfastness (AATCC 61 grade 4+)

Example 2: Sports Bra Technical Specification

  • Frame: Underwire-free with molded foam cups (density 0.18–0.22 g/cm³) and adjustable straps
  • Support fabric: 85% recycled polyester/15% spandex, 200 gsm, 3-way stretch
  • Impact rating: Suitable for high-impact activity (cup deflection <25mm under 15 kg load)
  • Seaming: Bonded cup seams; bound edges to prevent chafing
  • Care testing: Colorfastness to wash (AATCC 61 grade 4), elasticity retention after 50 wash cycles (≥90%)

What's Included

  • SKILL.md instruction file with skill overview and usage guidelines:
  • Performance Brief Template: customizable framework for all activewear categories with fabric, construction, and testing sections
  • Fabric Specification Checklist: properties to evaluate (weight, stretch, recovery, moisture management, thermal regulation)
  • Testing Standards Reference: ASTM and ISO protocols mapped to common performance properties (colorfastness, durability, fit stability)
  • Quality Control Matrix: critical control points and acceptance criteria for manufacturer inspection

Who It's For

  • Activewear designers — creating technical briefs that manufacturers can execute with minimal revision
  • Product development managers — coordinating between design and production with unambiguous specifications
  • Sportswear brand owners — ensuring performance claims are supported by measurable, testable criteria
  • Technical designers — translating design concepts into manufacturing-ready specifications and grading rules
  • Global sourcing professionals — communicating specifications to offshore manufacturers across language and region barriers

Best For

  • Creating initial technical briefs for new product launches (leggings, sports bras, jackets, compression gear)
  • Developing performance specifications that support marketing claims with testing protocols
  • Onboarding new manufacturers with detailed construction and quality expectations
  • Establishing size grading rules and fit specifications across product variants
  • Documenting design changes and sustainability considerations (recycled materials, low-impact dyes) for production teams
