A stem guard in cricket is a clip-on protective accessory that attaches to the back of a cricket helmet to shield the neck and upper spine from impact, particularly from fast, rising deliveries. It is designed to preserve head movement and comfort while increasing protection for the vulnerable neck area. Key points

• Purpose: Protects the back of the neck, upper spine, and sometimes jawline from short-pitched or rising balls.
• Attachment: Clips onto specific helmet models (most stem guards are designed to fit particular helmet brands or lines and will only fit those helmets).
• Materials: Commonly constructed from impact-absorbing materials such as TPU-based foams, honeycomb structures, or lightweight plastics, sometimes with additional crush foam for impact energy dissipation.
• Comfort and mobility: Designed to be lightweight and to maintain a batsman’s range of motion, with adjustable or multiple center-strap sizes on some models.
• Usage: Widely adopted in modern cricket at various levels, especially where fast bowlers are common, though adoption can depend on league rules and personal comfort.

Practical considerations

• Helmet compatibility: Ensure the stem guard is intended for your helmet model so it fits securely and does not interfere with movement or vision.
• Fit and sizing: Some guards come with multiple sizing options or adjustable straps to accommodate different neck widths and helmet sizes.
• Compliance and safety: While not universally mandated, many coaches and governing bodies emphasize neck protection, particularly in youth or high-velocity cricket environments.
• Maintenance: Regularly inspect clips, straps, and attachment points for wear or damage; clean according to the manufacturer’s guidance to preserve integrity.
