Exceptio

What Exceptio does

Exceptio is an independently owned UK-based hosiery manufacturer headquartered in Asfordby, Leicestershire, operating a second manufacturing site in Portugal via its wholly-owned subsidiary Peúgas Carlos Maia, Lda., and an EU trading entity in the Netherlands. The company produces bespoke jacquard knit and embroidered socks across 250+ knitting machines with a combined 46,000 sqm of manufacturing floor space and an annual output of 26 million pairs, serving four primary verticals: retail and fashion private label (including Harrods), sports and performance brands (technical socks for cycling, running, golf, skiing and uniformed services), corporate and promotional buyers, and licensed workwear (notably CAT/Caterpillar). Its product platform combines proprietary, trademarked yarn and sock technologies, namely Hydrocycled upcycled cotton, Hydrovent multi-channel moisture management, Pureco lifetime anti-bacterial treatment, the patented Prevent Sprain ankle stabilisation system, and Prevent Slip silicone grip patterning, supported by an in-house Sockology design centre and a Sockology 360° 3D artwork platform that produces manufacture-ready renders.

The business model is predominantly B2B contract manufacturing, structured around three revenue streams: private label manufacturing for retail and sports brands, promotional and corporate custom-branded socks, and own-branded product lines (Exceptio Sport, Hydrocycled, Pureco, Sole Happy, Toe Rags, Prevent Sprain, Prevent Slip, Toe Cap, and CAT licensed work socks) sold through retail and e-commerce channels including Sock Supermarket. Pricing is quote-based with low minimum order quantities (24 pairs embroidered, 100 pairs jacquard), no setup fees and free artwork origination (excluding embroidery digitisation), and a 30-day standard lead time on custom jacquard knit orders. Go-to-market is account-manager-led direct B2B sales, supplemented by a Client Resources portal, trade events (e.g., Merchandise World) and a presence across LinkedIn, Instagram, Facebook and TikTok.

Exceptio operates with 160 dedicated manufacturing staff under a family leadership team (Managing Director Rob Horsley; Creative Director Julia May; Production Director Emanuel Simones; Account Managers Joanne Horsley and Gareth Packer; Distribution James Horsley). The company holds an extensive certification stack: SMETA 4-Pillar A rating, BSCI A rating, ISO 9001:2015, OEKO-TEX Standard 100, OEKO-TEX DETOX TO ZERO, GOTS, GRS, and FSC packaging compliance. It is pursuing PAS 2060 / ISO 14068-1 carbon neutrality certification, currently sourcing more than 20% of energy from on-site solar and operating a 75% hybrid/EV corporate fleet. No external institutional investors, parent company or funding rounds are evidenced; the company is privately held by the Horsley family.

Broad incumbents

• Adidas: Global sportswear leader with multi-discipline technical sock lines. Comparable as a reference for the type of sports brand Exceptio manufactures for, but Adidas's scale, vertical integration, and brand power place it firmly as a broad incumbent rather than direct peer.
• Loro Piana: Italian luxury apparel group producing premium cashmere and merino knit hosiery within a broader luxury fashion portfolio. Comparable to Exceptio on premium cashmere and merino dress sock construction but operates as part of a much larger LVMH-owned luxury house.
• Nike: Global sportswear giant with an in-house technical sock range. Comparable as a customer-tier reference for Exceptio's sports brand manufacturing clients, but Nike operates at vastly larger scale and integrates sock production into a broader performance apparel portfolio.

Direct peers

• Wigwam Mills: US-based hosiery manufacturer producing performance, athletic, and work socks for brands and retailers. Comparable to Exceptio on multi-discipline technical sock manufacturing and B2B private-label production model.
• Pantherella: UK heritage hosiery manufacturer based in Leicestershire producing premium dress and fashion socks. Highly comparable to Exceptio given geographic proximity, premium positioning, and focus on quality knit and embroidered dress socks for retailers and private-label customers.
• Corgi Hosiery: Welsh premium sock manufacturer producing knit dress and casual socks for own-brand and private-label customers. Comparable to Exceptio on craft manufacturing, premium positioning, and bespoke/private-label service offering.
• HJ Sock Group (HJ Hall): One of the UK's largest sock manufacturers with private-label, retail, and sports sock lines plus own brands. Closely comparable in product breadth, scale, and B2B private-label service model to Exceptio's operations.
• Falke: German premium hosiery and sports apparel brand manufacturing technical and dress socks across multiple disciplines. Comparable to Exceptio on technical performance sock range, premium positioning, and European manufacturing footprint.
• Happy Socks: Swedish-designed colourful socks brand selling globally through retail and e-commerce. Comparable to Exceptio's lifestyle sock lines (Toe Rags, Sole Happy) and brand-led approach, though with a more consumer-direct distribution model.
• Burlington: Heritage sock brand with broad retail distribution across Europe producing dress and casual socks. Comparable to Exceptio on heritage European positioning, dress sock focus, and premium knit construction.
