7oz FR Shirts for Men - Flame Resistant Welding Longsleeve

Our review of the SKSAFETY 7oz FR shirt for men finds it best suited to trades that face occasional sparks and arc flash risk, like welding, blacksmithing, electrical and construction work. The single biggest reason to buy is straightforward: it combines a full-coverage long sleeve cut with fabrics, buttons and seams that are treated for flame resistance, giving reliable short-term protection and meeting NFPA and CAT II standards. Fit and comfort are praised by users, while the shirt's 7oz weight balances durability and protection for on-the-job wear.

Key Features

• 7oz 100% Cotton Fabric: The midweight cotton is treated for flame resistance so it slows burning and can self-extinguish in short spark exposures, offering practical protection for trade work.
• Arc Rating ATPV 9: With an Arc Thermal Performance Value of 9 and 3 Cal/cm2 listed, the shirt provides measurable arc flash protection suitable for CAT II tasks.
• Flame Resistant Construction: Fabrics, buttons and seams are all flame retardant, reducing weak points and ensuring the garment performs consistently in a thermal incident.
• Safety Certifications: Certified to UL and NFPA standards and classified CAT II, giving assurance the shirt meets recognized safety benchmarks for protective apparel.
• Work-Ready Design: Long sleeves and a traditional shirt cut make it easy to layer with other PPE while covering exposed skin in welding, electrical and roadside work.

Who It's For

This shirt is aimed at professionals and serious hobbyists who need flame resistant apparel that feels like a normal work shirt: welders, electricians, blacksmiths and construction workers who face brief spark or arc exposures. It is useful for surveyors and roadway crews who want a protective layer that does not restrict movement.

Those who require the highest level of continuous flame protection or inherently flame-resistant fibers for prolonged exposure should look to heavier specialty garments or garments rated for higher ATPV values. Also, if a very light summer-weight shirt is required, the 7oz treated cotton may feel heavier than alternatives.

Pros & Cons

Pros

• Comfortable, true-to-size fit noted by multiple users and easy to wear as a work shirt.
• Good value for money given the UL and NFPA certifications and CAT II classification.
• Complete flame retardant treatment across fabric, buttons and seams for consistent protection.
• Midweight 7oz cotton provides durability without being overly stiff.

Cons

• Some users find the fabric weight heavy for hot conditions; it may be too warm for prolonged summer use.
