Stride Republic Denmark: Tennis Skirts Built on Bi-Stretch Woven Polyamide
Stride Republic is a growing Denmark-based activewear label whose tennis skirts range now anchors its seasonal offer. When the design team planned a wider range with tighter launch dates, it needed a fabric partner able to guarantee construction consistency, documented performance and shade continuity across every production lot.
Stride Republic: reviewing the fabric swatch set for the tennis skirts programme
The challenge
The main risk in the project was slippage between sublimation prints and fabric shrinkage. The previous supply chain ran through a trading intermediary, so there was little visibility of the mill, no construction sheet and no test evidence behind the performance claims. Without that documentation the brand could not brief its retail partners with confidence.
The solution
We proposed a dedicated bi-stretch woven polyamide programme built around print trials on pre-shrunk fabric with wash-fastness validation. Development started with A4 lab dips and a full construction sheet covering fibre content, GSM, width, stretch and recovery, and colour fastness. Only after the brand approved hand feel and performance targets did the project move to a pre-production lot for fit sampling.

Implementation
- Development: lab dips and physical samples in 5 working days.
- Approval: colour, hand feel and stretch signed off in two rounds.
- Bulk: consolidated dye lots to hold shade continuity.
- QC: inline inspection plus final random inspection before packing.
- Testing: AATCC 79 absorbency on every bulk lot.
Specification delivered
| Parameter | Value |
|---|---|
| Fabric | bi-stretch woven polyamide |
| Weight | 300 GSM |

Results
The new bi-stretch woven polyamide programme helped Stride Republic raised the opacity rating to fully squat-proof under test. The tennis skirts line launched on schedule, and wash durability, opacity and fit consistency all held up through the first retail season. The brand has since extended the programme into additional colours and styles.
“The development process was transparent from the first sample. We finally had the data we needed to brief our retail partners with confidence.” — Stride Republic Product Team

Key takeaway
Moving from a trading model to mill-direct development removed the hidden risks in the supply chain. With documented construction, controlled shade management and inline quality control, Stride Republic could concentrate on design and marketing instead of firefighting production issues.
