SISSTR New Seas 4/3 U-Zip Full Suit Wetsuit - Black

SISSTR New Seas 4/3 U-Zip Full Suit Wetsuit - Black

The SISSTR New Seas 4/3 U-Zip Full Suit Wetsuit is built for women who need warmth, comfort and full-body coverage through colder surf sessions. Designed as a practical cold-water full suit, it gives the insulation needed for winter mornings, windy coastal days and longer sessions when staying warm keeps you surfing better for longer.

The 4/3mm thickness gives extra warmth through the body while still allowing movement for paddling, duck diving and everyday surf use. This makes it a strong option when a lighter 3/2mm suit is not quite enough, especially through southern Australian winter conditions and cooler shoulder-season sessions.

The U-Zip entry is designed to give the suit a secure upper-body fit while keeping the entry clean and surf-focused. Finished in classic black, the New Seas full suit has a simple, understated look that works across everyday surf conditions.

For surfers wanting a women’s winter wetsuit with reliable warmth, full coverage and practical performance, the SISSTR New Seas 4/3 U-Zip Full Suit is a strong cold-water option.

FAQ Section

What water temperature is the SISSTR New Seas 4/3 U-Zip Full Suit best for?

This wetsuit is best suited to cold-water surf around 10–15°C, depending on wind, session length and individual warmth preference.

What does 4/3mm mean in a wetsuit?

4/3mm means the wetsuit uses thicker 4mm neoprene through key warmth areas and 3mm material where flexibility is more important, such as the arms and shoulders.

What does U-Zip mean?

U-Zip refers to the wetsuit’s upper-body entry design. It is made to create a secure surf-focused fit while keeping the suit comfortable for paddling and movement.

Is this warmer than a 3/2mm wetsuit?

Yes. A 4/3mm full suit provides more insulation than a 3/2mm wetsuit, making it better suited to colder water, winter surf and longer sessions.

Who is this wetsuit best for?

This suit is best for women who need a warm full wetsuit for cold-water surf, winter mornings and regular cooler-condition sessions.

How should this wetsuit fit?

A wetsuit should fit firm and close to the body without restricting breathing, paddling or movement. If it is too loose, water can flush through and reduce warmth.
