The story
About Zone3
Owner · Founded by James Lock; employee-owned since 2024
Zone3 discloses its wetsuit and kit materials in some detail, including B-Prene limestone-based biodegradable neoprene sourced from Yamamoto, Yulex plant-based natural rubber on selected products, and recycled yarns and fabrics. Zone3 names no factories, cities or countries of manufacture, referring only to long-term relationships with specialist manufacturing partners. Zone3 lists no third-party certifications and says it is working towards B Corp certification. Overall Zone3 is transparent about materials but opaque about who makes its products and where.

Feature 1Zone3 makes triathlon wetsuits and swimwear from synthetic and plant-based rubbers rather than natural plant fibre. Its flagship suits use B-Prene, a limestone-based Yamamoto neoprene it describes as biodegradable, while its Yulex range uses plant-based natural rubber from the Hevea tree with a 100% recycled polyester lining, which it says cuts a suit's CO2 by up to 80%. Much of its triwear and swimwear also uses recycled yarns.
Feature 2Zone3 ships the majority of its range in water soluble Hydropol garment bags supplied by Aquapak, a patented polymer that dissolves in water and biodegrades in the marine environment without leaving harmful microplastics; Zone3 first packed products in these bags in 2023 and now uses around 85,000 of them a year.
Feature 3Zone3 is a registered member of the Surfers Against Sewage Ocean Network, joining more than 300 businesses tackling plastic pollution and sewage in UK coastal waters, and the Zone3 team has taken part in the Million Mile Clean, collecting around 75kg of waste at Milford on Sea Beach.
ShippingFree UK standard delivery is offered on all Zone3 orders over £75, with delivery costing £3.95 below that.
Shipping InternationalZone3 ships worldwide to over fifty countries, with any relevant duties clearly stated at checkout.
Shipping NotesReturns are accepted within 30 days in as-new condition, free in the UK with a provided label, though items used in water cannot be returned.

How Zone3 compares across published ratings
Wear it longer
Work out the real cost per wear
Use the price and realistic wear count to compare long-term value.
£0.00 per wear
Cost per wear is the honest test behind "buy less, buy better": a £200 coat worn 300 times beats a £25 one worn 5 times. It rewards wearing what you own and choosing things built to last.
