Rip Curl Size Guide+
Rip Curl wetsuits are designed with a performance-focused fit, so they should feel firm when first tried on without restricting movement or breathing. If you are between sizes, consider your height and chest measurements first, as these usually have the biggest impact on wetsuit fit. For best results, compare your measurements against the Rip Curl size chart before selecting your size. [open image in a new tab to enlarge]

Rip Curl Junior Flashbomb 4/3GB Zip Free Steamer Wetsuit - Slate Blue
The Rip Curl Junior Flashbomb 4/3GB Zip Free Steamer is built for young surfers who need serious winter warmth, flexibility and performance. Designed as a premium junior cold-water steamer, it gives groms full-body coverage, sealed comfort and the freedom of a zip-free entry system.
The 4/3mm thickness provides extra warmth through the body while still allowing movement through the arms and shoulders. This makes it a strong choice for winter surf, cold dawn patrols, longer sessions and young surfers who need more insulation than a 3/2mm wetsuit can provide.
The zip-free entry helps reduce bulk across the upper body and supports better mobility while paddling. The GB construction indicates glued and blind stitched seams, helping reduce water entry compared with basic flatlock stitching. The Slate Blue colourway gives the suit a clean, premium look while still keeping that classic Rip Curl surf feel.

FAQ Section
What water temperature is the Rip Curl Junior Flashbomb 4/3GB Zip Free Steamer 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 zip free mean?
Zip free means the suit does not use a traditional back or chest zip. This helps reduce bulk and can improve flexibility through the upper body.
What does GB or GBS mean?
GB or GBS generally refers to glued and blind stitched construction, which helps reduce water entry compared with basic flatlock stitching.
Who is this wetsuit best for?
This suit is best for junior surfers who need a premium, warm and flexible full steamer for colder surf conditions.
Is this warmer than a 3/2mm kids wetsuit?
Yes. A 4/3mm steamer provides more insulation than a 3/2mm wetsuit, making it better suited to colder water and winter sessions.
