Clubmartin — B2B textile wholesale and workwear supplier

Christian Habert is founder and owner of Clubmartin, a B2B textile wholesaler based in Stapelfeld near Hamburg. He launched Clubmartin in 2020 after founding the casual-wear brand Speek Fashion in 2015, and today leads the editorial direction of the Clubmartin knowledge platforms — the Textile Glossary (around 900 entries across 10 categories), roughly 7,200 product inspiration pages and 250+ category buying guides. Every article on this site is written or reviewed with hands-on knowledge of the actual products Clubmartin stocks, the manufacturers behind them and the daily reality of corporate wear, workwear and promotional textile procurement.

Background and experience

Christian Habert has run promotional-textile sourcing since 2015, first through Speek Fashion as a casual-wear label and from 2020 onwards as a dedicated B2B wholesaler. Clubmartin started with roughly 200 articles in 2020, moved into its own online shop in 2022, grew the range to over 5,000 articles in 2023, opened the current warehouse and showroom near Hamburg in 2024, and today ships more than 8,000 articles in sizes XS to 6XL in hundreds of colours. All of this feeds the editorial perspective: the texts on clubmartin.de are not written at arm's length but from the inside of a running wholesale operation.

Topics I write and review

Fibre science: cotton (combed, ring-spun, carded, organic), polyester (recycled rPET, microfibre), elastane, viscose, modal, lyocell/Tencel, wool blends, polyamide. Yarn properties, blend ratios and what they mean for feel, durability and print behaviour.

Finishing and decoration: screen printing, DTF/DTG, transfer printing, dye sublimation, embroidery, laser engraving, patch application. Which technique fits which textile and when a finish fails.
Certifications and standards: GOTS, OEKO-TEX Standard 100, OEKO-TEX Made in Green, bluesign, Fairtrade Cotton, OCS, Grüner Knopf, Fair Wear Foundation — what each label actually covers and where it stops.

Editorial process and review

Articles follow a defined pipeline: an AI-assisted draft is created from the primary data in our product database (manufacturer, article name, fibre composition, grammage, size range, colours, certifications), then checked against the manufacturer's own specification sheet, then reviewed by the Clubmartin textile editorial team before publication. Prices, stock levels and material specifications on product and category pages are pulled live from the shop database, so visitors see the same numbers Clubmartin uses internally. Where facts cannot be verified, the text says so explicitly instead of inventing details.

Content portfolio

The published work currently covers the Textile Glossary with roughly 900 terms grouped into fibres, fabrics, finishing, certifications, workwear norms, size systems and more; roughly 7,200 product-level inspiration pages that explain which garment fits which use case; and 250+ category-level buying guides. All of these are maintained as living documents — reviewed again whenever a manufacturer updates a spec or a new standard replaces an old one.

Editorial principles

No SEO spam, no click-bait headlines — every page has to earn its place by answering a real sourcing question.
Facts come from manufacturer specifications and recognised standards, not from guesswork.
Where a detail is unknown, the article says so instead of fabricating one.
AI assistance is used openly for research and drafting; final sign-off is editorial, not automated.
Competitor brands are not disparaged; comparisons stay on verifiable facts.

Industry network

As a wholesaler, Clubmartin works directly with manufacturer representatives from Fruit of the Loom, B&C, Russell Athletic, Stedman, Gildan, SOL'S, Karlowsky, Westford Mill, Promodoro and others. That contact is what makes the knowledge base useful: specification questions can be clarified at the source instead of being paraphrased from third-party resellers.
