How can I design a running apparel line that performs?

Focus on lightweight, breathable, and moisture-wicking fabrics, combined with ergonomic seams for comfort. Include a mix of essentials like singlets, shorts, and tights alongside performance-enhancing pieces. LSLONG’s R&D team supports patterning, fabric testing, and size grading to ensure garments meet global performance standards.

  • Offer both everyday and high-intensity options to appeal to a wider audience.

  • Incorporate antimicrobial treatments and odor-resistant finishes for long-lasting freshness.

What fabrics work best for running apparel?

Polyester blends, nylon, and Spandex provide stretch, durability, and moisture management. Jacquard knits and brushed surfaces add comfort for long-duration activities. For sustainable or premium lines, consider recycled polyester or compression fabrics. LSLONG maintains a comprehensive fabric library to meet both performance and branding requirements.

  • Balance breathability, weight, and durability for optimal lifecycle.

  • Select fabrics with colorfast finishes and minimal shrinkage for consistent quality.

Why is customization critical for running collections?

Customization helps brands establish identity, differentiate products, and enhance customer loyalty. Include colorways, reflective piping, zip details, or branded trims to elevate the product. LSLONG provides in-house embroidery, heat transfer, and label options to deliver fully branded running apparel.

  • Custom packaging and care labels improve perceived value.

  • Multi-market colorways and sizing options ensure broad consumer appeal.

How do I size and fit for global running markets?

Develop a detailed size chart covering XS–XL or broader ranges. Conduct athlete fit testing and body-standard sampling to ensure mobility and comfort. Include stretch panels, gussets, or ergonomic features to accommodate active movements. LSLONG supports scalable sizing solutions and flexible production for global distribution.

  • Display clear size guides to reduce returns.

  • Validate sizing with small-batch trials before full-scale production.

How can I ensure quality control during bulk running apparel production?

Implement a structured QC system including pre-production samples, inline inspections, and final audits. Test fabrics for wash durability, colorfastness, and seam integrity. LSLONG employs ISO-certified processes and a dedicated QC team to maintain consistent results across every batch.

  • Track production from dye lots to finished garments.

  • Maintain a corrective action system for rapid defect resolution.
