The O'Neill Youth Hyperfreak 5/4mm+ Chest Zip Hooded Fullsuit keeps young surfers warm and moving freely in the coldest lineups — built with the same premium Hyperfreak construction trusted by pros, scaled for kids.

Key Features:

• 5/4mm+ Thermal Rating — Extra-thick neoprene core with enhanced warmth layering for water temps from 42–52°F
• Integrated Hood — Built-in hood seals in warmth at the head and neck without adding a separate accessory or creating cold gaps
• Chest Zip Entry — Low-profile chest zip reduces water entry and provides a cleaner, warmer seal compared to back-zip suits
• Hyperfreak Firewall Lining — Thermal firewall lining traps body heat while quick-drying ultrastretch neoprene panels allow full arm extension
• GBS Seam Construction — Glued and blind-stitched seams throughout prevent cold water flushing at panel joints
• Youth-Specific Pattern — Cut and paneled for a young surfer's proportions — not a shrunken adult suit

Designed for young surfers who aren't letting winter slow them down, the Hyperfreak 5/4+ Hooded Fullsuit delivers professional-level warmth in a suit that grows with their progression. Whether they're logging winter sessions in NorCal or charging PNW beach breaks, this suit handles the conditions so they can focus on surfing.

Sizing & Fit: O'Neill youth sizing is based on height and weight. The Hyperfreak is designed with a snug performance fit — refer to O'Neill's youth size chart and size up if between sizes for easier entry and long-term wearability.

Care: Rinse with fresh water after every session. Hand wash with wetsuit cleaner as needed. Dry inside-out, away from direct sun and heat. Do not machine wash or tumble dry.
