01 — THE CHALLENGE
Kroen came to Hook and Eye UK with a clear vision: create premium, fashion-forward tracksuits that stood out in a highly competitive UK streetwear market — without compromising on fit, quality, or production standards.
The challenge was delivering technically advanced garments that balanced luxury aesthetics with commercial wearability. The brand wanted elevated silhouettes, custom panel construction, premium fabrics, and detailed finishing across multiple tracksuit styles.
At the same time, they needed a manufacturing partner capable of handling complex tech packs, precision sampling, and scalable bulk production while maintaining consistency across every garment.
Key challenges included:
Kroen needed an experienced clothing manufacturer who could execute at a high level from development through to final production.
02 — OUR APPROACH
Hook and Eye UK worked closely with the Kroen team throughout the full product development and manufacturing process, acting as both a technical partner and production specialist.
We supported the development of detailed tech packs for Kroen’s tracksuits, ensuring every garment specification was production-ready before sampling began.
This included:
Because the designs were highly detailed, precision in the tech packing
stage was critical to achieving the intended fit and premium finish.
Our team developed multiple sample rounds to refine:
The tracksuits featured some of the most complex construction work we’ve produced for a UK streetwear brand, requiring careful attention to panel execution, shape retention, and luxury finishing details.
Each revision was collaboratively refined with the Kroen team until every garment met the required standard.
Once approved, Hook and Eye UK managed the full bulk manufacturing process.
Our reporting system oversaw:
Consistency was essential, particularly due to the complexity of the garments and the premium positioning of the brand.
03 — THE OUTCOME
The outcome was a collection of premium tracksuits that exceeded expectations commercially and visually.
Every product Hook and Eye UK has tech packed, sampled, and bulk manufactured for Kroen has sold out.
The partnership helped Kroen:
The success of the collections demonstrated the value of combining strong creative direction with experienced technical product development and manufacturing execution.

04 — IN THEIR OWN WORDS
At KROEN we have been working with Hook and Eye for almost 3 years now, getting help on specific items and releases which we felt needed a more hands development approach to achieve the results we desired. From the off we were not disappointed, giving us all the tools we needed to get complex products through sampling with minimal time and money wastage.
Not only have they helped us get more from our products, they have also taught us an immense amount about the processes within this industry that were alien to us beforehand. We have done online and in person design + development sessions from which we have gained an immense amount of knowledge, taking it forward into our everyday practices.
We have always felt very well looked after by the whole team at Hook and Eye and I couldn't recommend them more to other young creatives or people starting out who need help seeing their most complex visions brought to life. We are now at a point where we rely less on the help and have managed to become more independent in our practices, but we will never forget the help and support we got from this wonderful team.
Thanks a million.
