The W663 is a workhorse. It’s the wader you put on at the beginning of your shift and take off when your day is over, every single day, in an environment that would wear out anything else. Oyster farms, fish factories, cranberries, shellfish, and chemicals are no strangers to the W663.
A 700gsm oil-resistant PVC layer forms the basis. This is no small amount of material – it resists abrasions, chemicals, oil, and stays flexible enough to be comfortable for your entire workday. All double welded seams eliminate stitching weaknesses – the PVC is bonded directly together and will keep water from getting in no matter what position you’re in.
The W663 comes with Dunlop wellington boots (non-safety). The nitrile sole resists oils, fats, acids, and organic solvents — the substances you’re most likely to encounter in aquaculture, food processing, and industrial cleaning environments. The tread pattern provides grip on the wet, muddy, and algae-covered surfaces that are standard on the job.
If your site requires certified steel toe cap and midsole protection, the W665ST with Dunlop Purofort Jobguard safety boots is the right choice.
Stormtide W663 Industrial Heavy Duty Chest Waders features:
- Heavy-duty 700 gsm PVC – Heavy duty PVC built for high-abrasion environments. Resists oils and industrial chemicals while remaining flexible enough for full-shift wear.
- Dunlop Wellington boots – Non-safety. Nitrile sole resists oils, fats, acids, and organic solvents, with a tread pattern engineered for grip on wet, slippery, and chemically contaminated surfaces.
- Drawstring cord on chest – Relaxed cut accommodates thermal mid-layers. The drawstring lets you cinch down for a more secure fit when working in deeper water or exposed conditions.
- Reinforced knee – Additional PVC layer at the highest-wear area, significantly extending garment life for workers kneeling on rough, abrasive, or debris-covered surfaces.
- Elasticated braces with industrial plastic clip buckles – Elastic gives freedom of movement across the full range of physical work. Fully adjustable for height and build, with enough room to layer underneath in cold conditions.
- Double-welded seams throughout – Every seam is welded, not stitched. No needle holes, no failure points. Stays completely waterproof however you move, bend, or kneel.
- Internal chest pocket – Large enough for a phone, gloves, or small tools. Keeps essentials dry, secure, and accessible without removing the wader.

Who Is the W663 For?
The W663 is the right choice for workers in environments requiring heavy-duty waterproofing and chemical resistance, but where certified safety footwear isn’t a site requirement:
- Shellfish and oyster farming
- Aquaculture and fish farming (catfish, trout, salmon)
- Cranberry harvesting
- Lobster and whelk fishing
- Commercial fishing — deck and processing
- Food processing and wash-down environments
- Forestry and survey work in wet terrain
- Construction and groundwork in wet conditions
FAQ
What’s the difference between the W663 and the W665ST? The W665ST uses 1100gsm PVC (57% heavier gauge) and is fitted with Dunlop Purofort Jobguard certified safety boots — steel toe cap and steel midsole. The W663 uses 700gsm PVC with Dunlop non-safety wellington boots. The W663 is the right choice for most commercial aquaculture and fishing environments; the W665ST suits the most demanding industrial and chemical environments, or sites with mandatory safety footwear requirements.
Are these waders oil and chemical resistant? Yes. The 700gsm PVC is oil-resistant, and the Dunlop nitrile sole resists oils, fats, acids, and organic solvents. For aggressive chemical applications, verify compatibility of PVC with specific substances in your environment.
Can I layer underneath? Yes — the relaxed fit is designed for layering. The drawstring chest closure and adjustable elasticated braces let you customise the fit over thermal clothing.
Are the boots removable? No — the boots are integrated into the wader body as a single unit, eliminating the leak risk at the boot join.
What sizes are available? Available in UK 7–11 / US 8–12 / EU 41–45. See the size guide for full measurements.
