Built to layer under armour

The 5.11 Rapid Assault Shirt in Dark Navy is engineered as a combat base layer to be worn beneath a plate carrier or load-bearing vest. Flatlock seams sit flush against the skin to cut chafing during long patrols, while the saddle shoulder construction keeps your range of motion free when you shoulder a rifle or reach overhead.

Stay cool under load

A poly, cotton and elastane knit body wicks moisture and dries fast, and stretch mesh side gussets vent heat exactly where armour traps it. The result is a top that stays comfortable in warmer conditions instead of leaving you clammy and overheated.

Rugged where it counts

The sleeves are cut from a tough poly-cotton ripstop with articulated, reinforced elbows, so the areas that take the most abuse hold up to hard use. The quarter-zip front and fold-down collar let you regulate temperature on the move.

Ready for kit and insignia

Dual sleeve pockets keep small essentials to hand, and hook-and-loop patch panels take flashes, flags and unit insignia. Adjustable cuffs seal out debris and lock in the fit.

Frequently asked questions

Is the Rapid Assault Shirt designed to be worn under armour?

Yes. It is built as a combat base layer for wear beneath a plate carrier or load-bearing vest, with flatlock seams that sit flush to the skin to reduce chafing and pressure points under kit.

What is the shirt made from?

The body is a poly-cotton-elastane knit jersey that wicks moisture and dries quickly, the sleeves are a durable poly-cotton ripstop with reinforced elbows, and the side gussets are a stretch mesh for airflow.

Will it keep me cool in warm weather?

It is designed to. The moisture-wicking body and mesh side gussets vent heat exactly where a vest traps it, so you stay drier and more comfortable in warmer conditions.

Can I attach patches and insignia?

Yes. There are hook-and-loop patch panels on each arm for flashes, flags and unit insignia, plus a storage pocket on either sleeve.

How should I care for the shirt?

5.11 recommends a cool machine wash and hang drying. Avoid fabric softener, which can coat the fibres and reduce the moisture-wicking performance over time.
