An independent gym apparel brand based in the United Kingdom approached Ready One to manufacture a performance activewear collection. Specifically, the brand targets fitness consumers with compression-fit garments designed for training and everyday athleisure wear. Furthermore, the brand required a factory capable of sourcing performance fabric, integrating mesh panels, and executing sublimation printing across three garment types. Brands planning a similar collection can start a custom gym apparel order directly with Ready One.
Project Requirements
Garment Types and Quantities
| Garment | Units | Decoration |
|---|---|---|
| Compression T-Shirts | 1,200 | Sublimation Printing |
| Performance Shorts | 1,000 | Sublimation Printing + Mesh Panels |
| Joggers | 600 | Sublimation Printing |
| Total | 2,800 | Sublimation throughout |
The brand commissioned a three-piece performance gym collection across 2,800 total units. Furthermore, each garment required a different construction approach while maintaining a consistent brand aesthetic across the range. Consequently, Ready One coordinated fabric sourcing, grading, and decoration as a single production programme. Moreover, a custom sportswear manufacturer capable of handling all three garment types in one run was the brand’s primary requirement.
Fabric and Decoration Specification
This collection specified 4-way stretch compression fabric — an 88% polyester and 12% spandex blend — for T-shirts and joggers. Specifically, the compression fabric delivers the stretch recovery, moisture-wicking, and shape retention performance gym brands require. Furthermore, the shorts incorporated performance mesh panels to provide ventilation and airflow in high-movement training garments.
Moreover, sublimation printing was selected for all decoration across the range. Specifically, sublimation bonds colour permanently into the fabric fibres rather than sitting on the surface — making it the preferred technique for compression wear that undergoes repeated washing and movement. In addition, custom woven labels and hang tags were included across the full 2,800-unit order.
Manufacturing Challenges
Sublimation Accuracy and Sizing Consistency on Stretch Fabric at Volume
The client had worked with other suppliers before approaching Ready One. Specifically, those suppliers struggled to maintain sublimation colour accuracy on stretch fabric at higher unit counts. Moreover, heat and pressure variation during sublimation causes colour shift on compression fabric if the process is not tightly controlled. Furthermore, sizing inconsistency was a recurring issue when cutting stretch material across large runs.
As a result, the brand required a factory with documented quality controls specifically covering stretch fabric and sublimation production. Therefore, Ready One’s six-certification standard and AQL inspection process were key factors in the brand’s decision to proceed. In addition, single-factory management across all three garment types eliminated the coordination risk the brand had experienced previously.
Ready One’s Solution
Fabric Sourcing — Compression and Performance Mesh Combination
Ready One sourced the 4-way stretch compression fabric to the brand’s performance specification. Specifically, the fabric was tested for stretch recovery, colour retention under sublimation heat, and dimensional stability after washing. Furthermore, performance mesh panels for the shorts were matched to the compression fabric in weight and finish. Consequently, both fabrics behave consistently across the sublimation process and hold their shape across the garment’s full range of motion.
Sampling and Pre-Production Approval
Ready One completed samples across all three garment types within 8 working days. Specifically, each sample demonstrated sublimation colour accuracy, mesh panel placement, and finished garment dimensions. Furthermore, the client reviewed and approved fabric, decoration, and sizing before bulk production began. Consequently, bulk cutting started only after every specification passed the sample review.
Sublimation Printing on Stretch Fabric
Ready One applied sublimation printing in-house across all 2,800 units under a controlled temperature and pressure programme. Specifically, compression fabric requires lower heat settings than woven fabric to prevent dye migration and colour distortion. Moreover, panel placement on the shorts was pre-mapped to account for mesh seam positions before sublimation was applied. Furthermore, colour profiles were locked at the sampling stage and held consistently across every batch in the bulk run.
Ready One holds all six certifications relevant to production at this level. In particular, ISO 9001, BSCI, SEDEX, GOTS, OEKO-TEX Standard 100, and WRAP apply to every order. According to ISO, ISO 9001 certification requires documented quality management systems covering every stage of production. Additionally, full certification documentation is available for client review and brand compliance purposes.
Quality Control on Stretch Fabric and Sublimation
Maintaining consistent sublimation quality across three garment types at 2,800 units requires systematic oversight at every production stage. Specifically, Ready One applies AQL inspection at cutting, mid-production, and final finishing. Moreover, sublimation colour accuracy, garment dimensions, and stretch recovery are each checked at mid-production. Consequently, colour variation and sizing deviations are identified and corrected before they affect the full batch.
Furthermore, Ready One’s quality control process covers the full AQL framework applied to every order. As a result, every garment in this 2,800-unit order was verified before DDP dispatch to the United Kingdom.
Production Results
Collection Delivery and Launch
Ready One dispatched the completed gym apparel collection within 30 to 35 working days from final sample approval. Furthermore, DDP delivery to the United Kingdom meant the client received the full consignment duty-paid with no additional import costs. In addition, the client launched the collection successfully and received strong initial sell-through across all three garment types.
Moreover, verified client reviews from brands across 40+ countries are published on the Ready One website. Consequently, brands can read real production accounts before placing their first order.
Reorder and Ongoing Partnership
Positive sell-through from the first collection led the client to re-order with expanded colourways and additional sizing options. In addition, the second order covered the same three garment types with updated sublimation artwork. Consequently, the partnership continues as an ongoing seasonal production relationship.
Furthermore, brands exploring private label gym apparel production can read direct client accounts before committing to a first order. Above all, consistent sublimation accuracy and stretch fabric quality are the foundation of every long-term partnership Ready One builds with fitness apparel brands.

Frequently Asked Questions
Can Ready One produce compression gym wear with sublimation printing?
Yes. Ready One manufactures compression T-shirts, shorts, and joggers using 4-way stretch fabric with sublimation printing applied in-house. Furthermore, sublimation on stretch fabric requires precise heat and pressure calibration to avoid distortion on the finished garment. Consequently, Ready One tests print placement and colour accuracy at the sampling stage before bulk production begins. Moreover, performance mesh panels can be combined with compression fabric in the same garment and production run.
What fabric does Ready One use for gym T-shirts, shorts, and joggers?
Ready One sources 4-way stretch compression fabric — typically an 88% polyester and 12% spandex blend — for gym T-shirts and joggers. Furthermore, performance mesh panels are integrated into shorts for ventilation and moisture management. Consequently, the fabric composition is confirmed at the sampling stage to match the brand’s performance specification. Moreover, GOTS and OEKO-TEX Standard 100 certified fabric options are available for brands with sustainability requirements.
What is the MOQ for a multi-garment gym apparel collection?
Ready One’s MOQ starts at 50 units per style. Moreover, multi-garment collections combining compression T-shirts, shorts, and joggers are managed as a single coordinated production run. Furthermore, custom woven labels and hang tags are available from the first order. In addition, pre-production samples are completed before bulk cutting begins across all garment types.
How long does a gym apparel collection take from sampling to DDP delivery?
Sample development for a multi-garment gym apparel collection typically takes 7 to 10 working days. Furthermore, bulk production for a collection of this scale completes within 25 to 35 working days from sample approval. Consequently, Ready One dispatches the full order DDP with no additional freight or import duty costs on arrival. In addition, lead times for larger orders are confirmed at the sampling stage.
Does Ready One provide DDP shipping for gym apparel orders to the UK?
Yes. Ready One ships all orders DDP worldwide, including to the United Kingdom. Furthermore, DDP means the client receives the consignment duty-paid with no additional import costs on arrival. Consequently, UK brands avoid unexpected customs charges and receive their order directly from the factory. In addition, the bulk order process covers the full timeline from sample approval to DDP delivery.
