关于我们
Since 2015. Functional garment specialists.
OBSESSIVE DESIGN CONCEPT → RETAIL EAST-ASIAN MARKET

The only design company specialising in functional garment solutions catered to the East-Asian market.

Welcome to KAIREN. We are the only product design studio in China that specialises in functional product development — with the track record to back it up.

Since 2015 we have helped our clients accumulate over USD $5 billion in gross sales value. Our work spans sportswear, outdoor, and casual-functional brands — concept through retail, including design guidelines, prototyping, supply chain, and marketing visual.

1Key clients with 6+ month contracts: NATUREHIKE, BANANA-IN, BENEUNDER, AE, MOODY TIGER. 2GSV figure accounts for products fully contracted to our studio (concept to retail), disregarding marketing and branding accounts.

SUPPLY CHAIN

We work with over 100 factories. That may not seem like much — but we chose ours to scale whenever you need.

China is a place where manufacturing experts are everywhere. In this cut-throat industry, we have provided innovation consultancy to brands like SHEIN, LI-NING, ANTA, and REGINA MIRACLE. Our clients have scaled from roughly USD $3M to USD $70M+ in eight months.

We work closely with partners who supply the world's most demanding apparel brands. The list below is partial.

INFORMATION EDGE

Shenzhen. Shanghai. Beijing. Front-row seat to the fastest-growing retail market on earth.

Working with our team does not only mean you have the confidence of the best players on your side. Our first-hand information on production and market trends translates directly to the quality of the designs in your products.

We do not consult from a distance. We are inside the factories, inside the showrooms, inside the trade fairs — and our clients carry that intelligence to market before it shows up in a report.

Work

业务
Four disciplines. One workflow, end-to-end.
FUNCTIONAL APPAREL ACCESSORIES IPs & CROSSOVERS BRAND & CONSULTANCY

We take a product from concept to the shelf. Material science, garment engineering, accessories, supply chain, and the visual layer that sells it.

KAIREN is structured as one team across three cities, organised by capability rather than by client. A single project usually moves through the studio in this order: brief → material & structure → prototyping → supply & tooling → marketing visual → first run.

01
FUNCTIONAL APPAREL

The discipline we are known for.

Sportswear, outdoor, and casual-functional — designed for the body and climate of the East-Asian consumer. Every garment we ship has been engineered against the climate where it will be worn, not against a marketing deck.

Our material science work has placed pre-production samples on the desks of NATUREHIKE, BANANA-IN, BENEUNDER, AE, and MOODY TIGER — among others. We work in nylon, wood-fibre, recycled polyester, and proprietary blends; we test against UV, water column, breathability, and abrasion before we cut a pattern.

02
FUNCTIONAL ACCESSORIES

Our expertise in functional design has led to an unprecedented success in accessories.

Our headwear products have consecutively surpassed global brands like NEW ERA and MLB in both quantity and global revenue. Our designs in gloves, bags, sleeves, shoes, and slippers have generated USD $80M+ per year in purchase orders since 2020.

Accessories are how we test material innovation at speed — and how our clients reach demographics that won't yet pay for a jacket.

03
IPs & CROSSOVERS

IPs and crossovers are butter to our bread. We know the flow in to out.

IPs and crossovers can be messy. There is the design, then the pre-confirmation, then prototyping, then the design approval from HQ — imagine going back and forth. We have worked with creative parties such as 3125C, The North Face, A. FourLabs, and Nike. We have built cross-brand product with DISNEY, WARNER BROTHERS, HASBRO, NICKELODEON, TENCENT, and BEARBRICK.

Our role on a crossover is to keep the original IP's voice intact while making the garment buildable, profitable, and on time. We are licensee-side, manufacturer-side, and creative-side at once.

1IP = Intellectual Proprietor. Engagements are bound by NDA; partner names listed are those we are publicly permitted to cite.
04
BRAND & CONSULTANCY

Design without the go-to-market is half a product.

We carry brand identity, marketing visual, and channel strategy when the engagement calls for it. Our marketing visual work has shipped alongside the product we designed — meaning the campaign is built on the engineering, not after it.

For brands that have outgrown an agency and not yet built their own studio, we operate as the extension between design intent and customer perception.

Fees

报价
The 6% rule. Capped, derivative, transparent.
Our fees are capped at 6% of your project budget.

Our fees are production-derivative — meaning we take 30–35% of your total expected production cost as a guideline. For high-scale projects, fees are priced as a percentage of GSV estimation.

The cap exists because we want to work on projects that excite us. The figures below are a general guideline. Talk to us about your business and see how our work together can bring us further.

FOUNDER · CHIEF DESIGN
CAELAN

CAELAN studied and worked with some of the most prolific Asian designers — Dai Fujiwara, Yohji Yamamoto, Kazuki Kuraishi, Koji Ogawa, and more.

He specialises in user-centric design and innovative structure. His work threads material science, garment engineering, and the question of what an Asian-built outdoor brand looks like when it stops imitating Western counterparts.

To shape a product is first to accept responsibility for who will wear it.
— CAELAN, FOUNDER

NARIZ

NARIZ worked behind the scenes on some of the most successful brand campaigns and marketing strategies in Chinese e-commerce.

His work for Okamoto and BANANA-IN has shown consistent results without sacrificing innovation in a fast-paced market.
