XGO FR Base Layers | Built for Mission-First Performance

Your base layer is your first line of defense—and XGO’s FR Phase 1 delivers everything you need under armor or kit. Trusted by military professionals and designed for demanding environments, this flame-resistant (FR) base layer is lightweight, breathable, and purpose-built for high-output performance.

Crafted from a patented blend of Modacrylic and FR Rayon, the XGO Phase 1 base layer provides inherent no melt/no drip protection that never washes out. Whether you're deployed, training, or working industrial environments, XGO helps you focus on the mission, not your gear.

Why XGO Stands Above the Rest:

  • Inherent FR Protection – Built at the yarn level for ASTM D6413-certified, no melt/no drip flame resistance.

  • Lightweight & Durable – Weighs just 4.8 oz/sq yd but holds up under pressure and daily wear.

  • Acclimate® Dry Tech – Advanced moisture-wicking to keep you dry and mission-ready.

  • AG47® Anti-Microbial Silver – Fights odor-causing bacteria so you stay fresh in the field.

  • Clean Seam® Comfort – Seamless feel designed for next-to-skin wear under armor, vests, or packs.

  • Designed for Movement – Rolled shoulders, underarm gussets, and extra length to reduce friction and stay tucked.

From the high rugby-style collar with Velcro neck for ventilation, to the UPF 25+ UV protection, every detail is built with the warfighter in mind. It’s time to ditch the scratchy, heavy FR gear and upgrade to the best.

XGO Phase 1 Base Layer Key Features:

  • FR Protection for Life of Garment

  • Moisture Management + Anti-Odor

  • Plate Carrier-Ready Design

  • UV Protection & Shrink-Resistant

  • Men’s Fit with Relaxed Comfort

FAQs: XGO FR Base Layers

What makes XGO different from other FR base layers?
Unlike treated fabrics, XGO’s FR protection is inherent to the fibers—meaning it won’t wash out or degrade over time. Plus, it’s lighter, more breathable, and far more comfortable.

Is this base layer compatible with plate carriers and body armor?
Absolutely. With rolled shoulders and underarm gussets, it’s specifically engineered to reduce friction and irritation under armor or packs.

Will it shrink after washing?
No. The XGO Phase 1 base layer is made from a shrink-resistant fabric that maintains shape and size wash after wash.

Can I wear this for non-tactical use or industrial jobs?
Yes. While it's designed for tactical and military performance, its FR rating and all-day comfort make it ideal for industrial or utility work environments too.

Does it help manage sweat and odor?
Big time. Acclimate® Dry technology keeps you dry, and AG47® silver antimicrobial fibers fight odor so you stay fresher longer.
