Knyx C5 Iso Pro Cricket Helmet
Overview
The Knyx C5 Iso Pro is the engineered product for serious cricketers who demand lightweight construction, uncompromising protection, superior ventilation, and an advanced fit system in a single helmet. Sitting a step below the carbon composite C7 range, the C5 Iso Pro delivers the same Isofit adjustment system, RIM protection technology, and EVS ventilation in a durable impact modified polymer shell — making professional-grade fit and protection technology accessible to a wider range of players. The innovative Isofit ratchet mechanism allows one helmet to accommodate a wide range of head sizes and shapes, while aerospace-grade titanium facial protection and the Maglock magnetic buckle complete a helmet that punches well above its positioning.
Design and Materials
The C5 Iso Pro is built around an impact modified polymer shell with a matte painted finish, providing dependable protection and lasting durability in a lightweight package suited to serious club and developing cricketers. Inside, a high-density EPP liner delivers multi-impact shock absorption, while the Radial Impact Mitigation system handles impacts from every direction using elastic shock absorption. The Isofit ratchet system sits at the core of the internal architecture — rather than being locked into a fixed shell size, players simply turn the dial to adapt the helmet to the precise shape and size of their head, giving a genuinely personalised fit that no standard sizing system can replicate. The Engineered Ventilation System drives continuous cooling airflow through strategic intake and exhaust channels, and KoolForm comfort padding in varied thicknesses adds a further layer of internal comfort. A Neck Shield Pro — built with impact modified polymer and high-density EPP — is included with every helmet.
Key Technologies
Isofit Personalised Adjustment System: A micro-adjustable dial-in ratchet built into the shell that allows a single helmet to fit a wide range of head sizes and shapes. Players turn the ratchet straight out of the box until the fit feels exactly right — no fixed sizes, no compromises, just a secure and personalised hold every time.
Impact Modified Polymer Shell: A lightweight yet durable shell engineered for serious cricketers who need dependable protection and long-lasting performance without the weight of traditional helmet materials.
High Density EPP Liner: A multi-impact absorbing expanded polypropylene liner designed to mitigate extreme impacts and provide consistent protection across repeated use.
Radial Impact Mitigation (RIM): An elastic shock absorption system engineered to handle impacts arriving from every direction, providing comprehensive multi-directional protection at the crease.
Engineered Ventilation System (EVS): Strategically positioned intake and exhaust channels drive continuous cooling airflow across the head, ensuring maximum comfort during extended periods of play.
KoolForm Comfort Liner: Wide-surface moisture-wicking padding included in varied thicknesses, allowing players to fine-tune the internal fit and comfort alongside the Isofit ratchet system for a truly personalised wearing experience.
Ultralight Titanium Facial Protection: Aerospace-grade titanium construction delivers unparalleled facial protection with minimal added weight, maintaining clear sightlines without compromise.
Maglock Buckle System: A self-aligning magnetic quick-release buckle that can be fastened and released instantly, even with batting gloves on — removing a key distraction at the crease.

VKS Review
The Knyx C5 Iso Pro is a compelling option for serious club cricketers who want access to premium fit and protection technology. The Isofit ratchet system is as impressive here as it is across the rest of the Knyx range — dialling in a precise, personalised fit across a wide range of head sizes and shapes within a single shell remains one of the most practical innovations in cricket helmet design. The titanium grille and Maglock buckle are premium touches that you would not expect at this level, and the RIM system and EVS ventilation ensure the C5 Iso Pro holds its own on protection and comfort throughout a full day's cricket. An excellent all-round helmet for players who take their game seriously.
Q&A Section
Q: Who is the Knyx C5 Iso Pro designed for?
A: It is designed for serious club and amateur cricketers who want lightweight construction, advanced fit technology, and dependable protection in a well-priced helmet.
Q: How does the Isofit system work?
A: The Isofit system uses a micro-adjustable dial-in ratchet built into the helmet shell. Players simply turn the ratchet to expand or contract the fit until it feels perfectly secure and comfortable. Because the system accommodates a wide range of head sizes and shapes within a single shell, there is no need to choose between fixed sizes — the helmet adapts to the player rather than the other way around.
Q: Does one size really fit a range of head sizes?
A: Yes, that is the core principle behind the Isofit system. The micro-adjustable ratchet allows the single shell to adapt across a meaningful range of head sizes and shapes, giving every player a secure, personalised fit without the limitations of conventional sizing.
Q: How does the C5 Iso Pro differ from the C7 Iso Pro?
A: The C5 Iso Pro shares the same Isofit system, titanium grille, Maglock buckle, RIM protection, and EVS ventilation as the C7 Iso Pro but features an impact modified polymer shell rather than the carbon composite shell found on the C7 — making it a more accessible option while retaining many of the same key technologies.
Q: What does the Radial Impact Mitigation system do?
A: The RIM system uses elastic shock absorption to handle impacts arriving from any angle, providing comprehensive multi-directional protection that goes beyond what a standard liner alone can offer.
Q: Is a neck shield included?
A: Yes, a Neck Shield Pro — constructed from impact modified polymer and high-density EPP — is included with every C5 Iso Pro helmet.
Q: How does the Maglock buckle work?
A: The Maglock is a self-aligning magnetic buckle that fastens and releases instantly with a single motion, designed to be operated easily even with batting gloves on.
Q: How does the ventilation system work?
A: The Engineered Ventilation System uses strategically positioned intake and exhaust channels to drive a continuous flow of cooling air across the head throughout play.
