The Essential Guide to Buying a Winter Wetsuit
When the temperatures drop and the waves get colder, the right winter wetsuit becomes essential. At Circle One, we’ve been helping cold water surfers, swimmers, and watersports enthusiasts stay warm and protected for over five decades.
Here’s your definitive guide to choosing the perfect winter wetsuit—and the neoprene accessories—to keep you comfortable and confident in cold conditions.
Why Choose a Winter Wetsuit?
Winter wetsuits are designed to insulate your body against cold water and biting winds. They use thicker neoprene and advanced seam technology to trap a thin layer of water between your skin and the suit. Your body warms this water, creating an effective insulating barrier.
A close, snug fit is critical—too loose and cold water will flush through; too tight and your movement will be restricted. Always refer to our size guides or visit us in-store to ensure the best fit.
What Thickness Wetsuit for Winter?
Choosing the right wetsuit thickness depends on both water temperature and your tolerance to cold. Here’s our winter thickness guide:
5/4/3mm or 5/3mm Full-Length – The go-to option for UK winter surfing and watersports. These suits offer excellent core warmth with thinner neoprene at the limbs for flexibility.
4/3mm Full-Length – Not strictly a winter thickness but a great option for late Spring or if you're really active and generate heat quickly. Offers a strong balance between warmth and mobility.
💡 Tip: If you're involved in wind-exposed activities like kitesurfing or sailing, consider wetsuits with wind-resistant chest and back panels for extra protection.
Entry Systems: Which One Is Right for You?
Which entry system you choose (Back or Chest Zip entry) is really down to personal choice but here's a quick reference:
Back Zip
-Easier to get on and off
-Slightly less water-tight than Chest Zip
Chest Zip
-Better water seal and shoulder mobility
-Slightly trickier to put on but preferred for performance and warmth
Wetsuit Seams & Stitching
Seam construction is a major factor in a wetsuit’s ability to retain warmth in winter conditions, that is why ALL Circle One winter wetsuits benefit from GBS construction. GBS seams are designed to prevent cold water flushing and maximise thermal retention.
Glued & Blind stitched (GBS) Benefits:
-Neoprene panels are glued and stitched partially through
-Limits water entry while maintaining comfort and stretch
-A must-have for winter suits

Essential Winter Accessories
Wetsuit accessories help maintain circulation and protect extremities, which are the first to feel the cold. For serious winter sessions, we recommend:
5mm Neoprene Boots – Insulated and snug-fitting to keep your feet warm and protected.
Wetsuit Gloves – Choose a pair that offers both warmth and grip without restricting dexterity.
Wetsuit Hood or Cap – Essential for minimising heat loss from your head in cold conditions.
