If you spend time on the water in the UK, a good wetsuit isn’t a luxury — it’s the difference between “one more run” and “I’m done”. At The SUP Company we see the same thing every season: people buy too cold, too loose, or too awkward to get on and off… then wonder why they don’t go as often.
This guide is designed to make choosing simple. I’ll cover the real-world stuff (wind chill, fit, how you move in different sports), the tech that matters (seams, linings, zips), and then point you to the exact wetsuit styles and ranges we stock.

Step 1: Choose your wetsuit thickness (the UK-friendly approach)
Wetsuit thickness is the first big decision — but it’s not just about “water temperature”. The sport matters because of wind chill and how much you’re moving.
Rule of thumb: if you’re winging/kiting, go warmer than a surfer would (you’re stood up, wet, and the wind is relentless). If you’re SUPing/kayaking, you might not need quite as thick — but you’ll want comfort, stretch, and easy shoulder movement.
UK wetsuit thickness cheat sheet
| Season | Surf / SUP (typical) | Wing / Kite (wind chill) | Notes |
|---|---|---|---|
| High summer | 2/2 to 3/2, or a shorty/Long John | 3/2 (often full length) | Long sessions? Add boots if you get cold feet. |
| Spring / Autumn | 4/3 “workhorse” | 4/3 to 5/4 | If you want one suit for most of the year, 4/3 is usually it. |
| Winter | 5/4 (often hooded) | 5/4 hooded + boots/gloves | Seals + lining matter as much as thickness. |

Step 2: Pick the right wetsuit style for your sport
Full suit (best all-rounder)
If you’re doing a bit of everything — SUP, surf, foil, wing, kayak — a full suit is the most versatile. For the UK, a 3/2 covers late spring through summer, and a 4/3 is the “most used” suit for spring-to-autumn.
Shorty (maximum mobility in summer)
Shorties are brilliant for warm days, coaching, quick sessions, and anyone who hates overheating. They’re also a great travel suit.
Long John / Long Jane (popular for SUP & paddlesports)
This is a classic setup for SUP and paddling: sleeveless warmth + total shoulder freedom. Great for warmer months, and also ideal for layering with a neoprene top if the wind picks up.
Step 3: Chest zip vs back zip (what actually matters)
This is the decision that most affects day-to-day “faff factor”. Here’s the honest breakdown:
Chest zip (front zip)
Pros: generally warmer, better sealing, less flushing — ideal for winter and windy sports.
Cons: slightly more technical entry/exit (once you’re used to it, it’s fine).
Back zip
Pros: easiest on/off, very practical for beginners, coaching, casual sessions.
Cons: can flush a bit more in colder, rougher conditions (modern designs are far better than they used to be).
Step 4: The wetsuit “tech” worth paying attention to
Seams (warmth + durability)
- Flatlock: comfy and flexible, but best for warmer water (more water can pass through).
- GBS (glued & blind stitched): the UK favourite for colder seasons — warmer and less flushing.
- Taped / sealed seams: extra warmth and durability where it matters most (typically in winter suits).
Linings (warmth without adding bulk)
Modern thermal linings are a big deal. Two suits can both be “5/4” and feel totally different — one dries faster, feels warmer, and stays comfortable longer because of the lining and sealing.
Paneling + stretch (especially for SUP, wing & paddling)
If you’re paddling or winging, your shoulders and upper back do a lot of work. Look for suits known for flexibility and smart panel layouts — you’ll feel it on longer sessions.
Step 5: Fit & sizing (the bit that makes or breaks a wetsuit)
A wetsuit should feel snug — like a second skin — without restricting breathing or shoulder movement.
Fit checklist
- No big air pockets: especially in the lower back and behind the knees.
- Neck seal comfortable: firm, but not choking.
- Shoulders free: you should be able to paddle/raise arms without fighting the suit.
- Crotch sits correctly: if it’s hanging low, it’ll rub and pull.

FAQs
What thickness wetsuit do I need for the UK?
Most people end up with a “two suit” setup: a 3/2 for late spring through summer, and a 4/3 or 5/4 for spring/autumn and winter. If you do a lot of winging/kiting, lean warmer because wind chill is the real killer.
Is a 4/3 enough for winter?
For most UK winter sessions, a 5/4 (often hooded) is the safer bet — especially for wing/kite. Some surfers can push a 4/3 with boots/gloves, but comfort drops fast once the water and air temps fall.
Chest zip or back zip — which should I choose?
Back zip is easiest on/off and great for casual use. Chest zip is typically warmer with better sealing — ideal for colder months and windy sports. If you’re unsure, tell us your sport + when you go out and we’ll steer you.
How tight should a wetsuit be?
Snug, with no big air pockets — but not restrictive. If it’s loose at the lower back or behind knees, it’ll flush cold water. If it’s crushing your shoulders or you can’t breathe comfortably, size up or try a different cut/brand.
What accessories make the biggest difference in cold water?
In order: boots, then gloves, then a hood. Those three extend your season massively. After that, a proper hanger + change mat makes your kit easier to live with and helps it last longer.
