Stride Republic Sweden: High-Waist Yoga Leggings Built on Nylon/Spandex
Stride Republic is a growing Sweden-based activewear label whose high-waist yoga leggings 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 high-waist yoga leggings programme
The challenge
The main risk in the project was shade variation between production lots. 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 nylon/spandex programme built around a consolidated dye-lot programme with retained shade standards. 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 61 colour fastness on every bulk lot.

Results
The new nylon/spandex programme helped Stride Republic cut customer returns by 32% in the following season. The high-waist yoga leggings 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.
