Every time I check Remixd’s wetsuit section, one suit is sitting near the top with half its sizes already sold out: the Vissla 7 Seas 4/3 Full Chest Zip. It’s currently discounted to £249.95 from £329.95, so I dug into the spec sheet and a stack of independent gear reviews to see if the hype holds up.
What it’s made of
The suit is built from Japanese limestone-based neoprene, an 80/20 blend of limestone-derived rubber and nylon that Vissla markets as lighter, warmer, and stretchier than petroleum-based neoprene. Inside, a Thermal Fever Fiber lining adds insulation and dries fast between sessions.
The fabric is dope-dyed and laminated with a water-based, Bluesign-approved process, which cuts down on the solvent-heavy dyeing most wetsuits still use. Seams are triple glued and blind stitched, sealed further with Vissla’s Super Stretch Neo 3.0 tape.
What buyers and testers are actually saying
Remixd’s own product page doesn’t carry reviews yet for this specific listing, but the 7 Seas 4/3 has been reviewed independently by surf outlets who put it through actual sessions. The Inertia’s gear testers found it warm and flexible without feeling flimsy, calling it a strong fit for younger or lighter surfers who want mobility over bulk.
Surfd went further, naming the 7 Seas 4/3 one of the best value winter wetsuits on the market and noting testers felt just as warm in it as in a heavier 5mm suit, thanks to the Thermal Fever lining. That’s a meaningful claim for a suit built for cold Atlantic and Welsh coastal water.
Fit, entry, and everyday details
Entry is through an angled chest zip, which testers point out is easier to line up solo than a back-zip design. You don’t need to yank two zipper halves together behind your own neck to get it closed.
A Glideskin neck seal and liquid-taped cuffs keep flushing to a minimum, and an upcycled Supratex knee pad adds durability where wetsuits usually wear out first. Remixd lists this listing’s cold water range at 51 to 58°F (11 to 14°C), so it’s built for proper winter conditions, not shoulder-season paddles.
On Remixd, it comes in Black, Naval, and Dark Slate, in sizes MS, MT, XL, LT, M, and L, though most sizes were showing low stock or sold out when I checked. That kind of sell-through, on a suit this specialized, is a decent proxy for demand.
Warranty and how it compares
Vissla backs the seams and neoprene with a 1-year warranty, which is standard for a suit at this price point. Against Remixd’s own catalog, it sits above the entry-level 3/2 suits in warmth and below the heaviest 6mm winter builds in flexibility, which is exactly the middle ground most UK and Welsh surfers need for the bulk of the season.
Should you buy it
If you surf year-round in cold water and want a suit that trades bulk for genuine warmth, this is a strong pick, especially at the current sale price. Check your size chart carefully before ordering, since popular sizes are moving fast.
