Features

Tested Fire Safety for Vest Wearers

• Proven to resist intense heat without igniting, melting, or dripping—providing a critical safety barrier against sparks, embers, or unexpected fire hazards in work or outdoor settings.
• Extinguishes instantly when flame is removed, with only minimal 3mm charring that doesn’t affect performance. The zipper stays fully functional, ensuring quick vest removal if needed.

Heat-Sealed & Open End: Vest-Specific Practicality

• Heat-Sealed Tape Edges: Prevents fraying and unraveling, extending the life of your vest (no more loose threads or damaged zippers after repeated washing). The sealed design also adds an extra layer of flame resistance.
• Easy On/Off Open End: Lets you slip the vest on or off in seconds—no need to pull over your head, making it ideal for layered outfits or quick gear changes. The secure plug-in closure stays put during wear, even with movement.
• Vest-Friendly Design: Size 5 resin construction is lightweight and low-profile, fitting seamlessly into vest fabrics without feeling bulky or restricting arm movement—critical for active work or outdoor adventures.

• Ergonomic non-slip slider: Easy to grip and pull, even with gloves or sweaty hands—perfect for construction workers, welders, or outdoor guides.
• Washable & long-lasting: Tape retains fire-resistant properties and heat-sealed edges through repeated laundering, maintaining vest performance for years.
