Specifications

Compatibility

The 5.11 Tactical V.XI Sigurd Short Sleeve Shirt is designed to function as a standalone top or as the foundation of a layering system. The close-fitting athletic cut sits smoothly under plate carriers, soft body armor, and tactical shirts without bunching or restricting range of motion. The foldable rugby collar is compatible with both open-collar and high-collar outerwear.

The 4" x 6" loop patch platforms on both sleeves accept standard hook-backed patches, unit identification tabs, and IR panels, making the shirt patrol-ready right out of the box. The flat lock seam construction ensures the shirt does not create pressure points under chest rigs, plate carriers, or duty belts during extended wear.

The shirt is sized in Standard fit for men, ranging from XS through 4XL. It is not designed for women's sizing or youth sizing. If you are between sizes, 5.11 recommends sizing up for layering use.

Intended Users

The 5.11 Tactical V.XI Sigurd Short Sleeve Shirt was built for professionals who stay active in demanding environments and cannot afford to be slowed down by an uncomfortable base layer.

Law enforcement officers rely on the Sigurd during patrol, fugitive operations, and plainclothes assignments where a clean, low-profile athletic fit works under a vest or concealed carrier without printing or bunching.

Military and special operations personnel wear the shirt as a performance base layer during training evolutions, field operations, and under full kit. The loop patch platforms on the sleeves make it compatible with unit identification requirements.

Range instructors, competitive shooters, and gun enthusiasts appreciate the Range Red colorway as a high-visibility option at the firing line, while the flat lock seams eliminate any hotspot issues during sustained shooting sessions.

EMS, firefighters, and public safety professionals working in warm conditions or high-exertion environments benefit from the Cryo-Tac moisture management and anti-odor properties during long shifts.

Tactical athletes, preppers, and outdoor enthusiasts use the Sigurd as a training shirt, hiking base layer, or physical conditioning top, taking advantage of its athletic fit and breathable mesh construction.
