1. Project Overview
AM Powerfit, a personal trainer–led fitness brand, aimed to expand its identity into physical sportswear. The objective was to develop a functional and branded sports tank top suitable for training environments, while also being viable for small-batch merch production.
The result is a lightweight, performance-oriented tank top designed for both athletic use and brand visibility within the AM Powerfit community.
2. Product Concept
The product developed is a men’s/women’s sports tank top intended for:
- Gym training and functional fitness
- Personal training sessions
- Branded merchandise for clients and team members
- Small-scale retail drops for brand building
The design focus was on comfort, mobility, and durability under repeated training conditions.
3. Material Specification
The chosen fabric is:
KETTEN – 92% PES / 18% EA – 280gsm
This composition delivers:
- High durability (PES / polyester base) for long-term wear and wash resistance
- Strong elasticity (EA / elastane content) supporting full range of motion during training
- Medium-heavy 280gsm weight, giving the garment structure, stability, and a premium feel rather than a thin performance singlet
- A balance between compression and comfort, suitable for strength training and general fitness use
Overall, the material supports a “performance premium” positioning rather than fast-fashion sportswear.
4. Brand Context: AM Powerfit
AM Powerfit operates as a personal trainer brand focused on performance coaching and community-based fitness. The introduction of apparel serves multiple purposes:
- Strengthening brand identity in the gym environment
- Creating team cohesion through uniform-style apparel
- Offering merchandise to clients as part of the coaching ecosystem
- Expanding into lightweight lifestyle commerce
The tank top acts as both functional training gear and a brand extension tool.
5. Production & Cost Structure
The project was evaluated under two production scenarios:
Small Batch Production (< 50 units)
- Estimated unit cost: 16€ – 18€
- Higher cost due to:
- Limited material bulk purchasing
- Setup and sampling distribution across fewer units
- Higher relative production overhead
Larger Batch Production (200+ units)
- Estimated unit cost: 11€ – 12€
- Cost efficiency achieved through:
- Bulk fabric procurement
- Optimized manufacturing workflow
- Reduced per-unit setup and handling costs
6. Key Insights
- The design is scalable: cost efficiency improves significantly with volume increase
- The fabric choice supports both performance use and premium branding
- Even at low MOQ, the product remains commercially viable for niche brand merchandising
- The strongest value proposition lies in combining training utility with brand identity exposure

7. Conclusion
The AM Powerfit sports tank top demonstrates how a small personal trainer brand can effectively transition into apparel merchandising without compromising quality. With a strong fabric foundation and scalable production model, the product is positioned as both a functional training garment and a brand-building asset.
