Entry-Level Sleeveless Triathlon Wetsuit for Freedom, Stability and Confidence in Open Water

The ZONE3 Ascend Sleeveless Wetsuit is designed as a straightforward, entry-level open-water wetsuit that helps swimmers build confidence from their very first sessions. With a sleeveless cut and balanced buoyancy profile, it prioritises natural movement, stability in the water, and consistent performance for training and triathlon use.

Why Choose the ZONE3 Ascend Sleeveless Wetsuit?

Sleeveless Design for Maximum Freedom

The sleeveless construction removes restriction around the shoulders, allowing a completely natural stroke path and smoother rotation in the water. This makes it especially comfortable for swimmers focused on technique and endurance.

Balanced Buoyancy for Stability

A combination of 2 mm and 3 mm neoprene panels helps support body alignment, improving horizontal position and reducing drag for more efficient swimming.

Low-Drag Surface Technology

SCS-coated neoprene and Speedflo zones reduce surface resistance, helping the wetsuit glide smoothly through the water and maintain momentum with each stroke.

Durable Lower-Body Construction

Reinforced materials in high-wear areas such as the legs, knees and shins improve durability while maintaining flexibility where it matters most.

Comfortable, Secure Fit

A zigzag Velcro adjustable neck closure provides a secure yet comfortable seal, while flatlock seams enhance flexibility and reduce irritation during longer swims.

Improved Visibility

Reflective Silver 877c detailing helps improve visibility in low-light or early-morning conditions, adding an extra layer of safety.
