The global activewear market is booming.

Key Focus Areas for Your Brand

1. Design & Tech Pack

This is the blueprint for your apparel. A detailed tech pack translates your vision into a technical guide for the manufacturer.

Include precise measurements, seam types, stitch details, fabric composition, color codes (Pantone), and placement for logos and labels.

2. Fabric Sourcing

The fabric is the foundation of performance. The right material must balance function, feel, and aesthetics.

Focus on synthetic, moisture-wicking fibers like Polyester, Nylon, Spandex, and Lycra. Consider fabric weight, compression level, and four-way stretch.

3. Sampling & Prototyping

Before full production, we create samples based on your tech pack. This is a critical step for quality control and refinement.

Test the fit, comfort, and durability during movement. This is your opportunity to make crucial adjustments to ensure the final product is perfect.

4. Production & Branding

Once the final sample is approved, we move to full-scale, ethical production, including all your custom branding elements.

This includes logo application (e.g., screen printing, heat transfer), custom-branded tags, and packaging that reflects your brand identity.

Critical Decisions in Designing Your Workout Clothes

Attention to detail during the design phase will set your brand apart.

1. Selecting the Right Fabric for Performance

The single most important factor in quality activewear is the fabric. Your choice will dictate the garment's performance and comfort.

Wicking is Non-Negotiable: Use synthetic fibers that pull sweat away from the body (wicking) to keep the wearer cool and dry. Materials like polypropylene, polyester blends, and Lycra are ideal.
Avoid Cotton for Sweaty Workouts: While comfortable for casual wear, cotton absorbs moisture, becoming heavy and uncomfortable during intense exercise.
Match Fabric to Activity: A lightweight, breathable fabric is perfect for running tops, while a thicker, high-compression fabric with excellent opacity is essential for leggings and sports bras.

2. Engineering the Perfect Fit

Workout clothing must support the intended activity without restricting movement.

Activity-Driven Design: The fit should always complement the function. Yoga apparel requires maximum flexibility and stretch, while running gear might prioritize lightweight layers and compression for muscle support.
Compression vs. Loose Fit: While some athletes prefer a looser fit for activities like weightlifting, most modern activewear utilizes a tighter, form-fitting design. This "second-skin" feel accentuates the physique and prevents fabric from interfering with movement.
Small Production Runs: We specialize in small run manufacturing, allowing you to test different fits and styles with your audience without committing to a massive inventory.
