The Bulwark Men’s FR Two-Tone Base Layer MPS4 is designed to serve as a dependable first layer of flame-resistant protection while offering comfort and functionality for daily industrial wear. Made with EXCEL FR fabric, this base layer meets recognized flame-resistant standards, providing protection against flash fire and arc exposure while maintaining a lightweight and breathable feel.

Its two-tone design adds a professional, modern appearance while improving visibility and garment definition in layered workwear systems. The concealed chest pocket offers discreet storage for small essentials, allowing workers to keep items secure without compromising safety or comfort. The short-sleeve design makes it ideal for warmer environments or as a base layer under jackets and outerwear.

Engineered for comfort, the fabric wicks moisture away from the skin, helping regulate body temperature during physically demanding tasks. The soft hand feel reduces irritation, making it suitable for extended wear throughout long shifts. The garment’s athletic fit allows for natural movement without restriction, supporting bending, reaching, and lifting.

Durable construction ensures the MPS4 retains its protective properties and shape through repeated laundering. Ideal for electrical, industrial, and energy-sector professionals, this FR base layer combines safety compliance, comfort, and practical design. It is an essential foundation garment for workers who require reliable flame-resistant protection from the first layer outward.
