The king of performance base layers

The 5.11 V.XI Sigurd Long Sleeve Shirt in Ranger Green sits at the top of 5.11’s base-layer line, loaded with mission-specific construction. Built from a 78% nylon / 22% elastane warp-knit stretch mesh, it delivers the freedom of movement and next-to-skin comfort demanded by serious users.

Cool-touch Cryo-Tac technology

The fabric carries 5.11’s Cryo-Tac treatment, giving a genuine cool-to-the-touch feel that works alongside enhanced moisture-wicking to help manage heat when you are working hard. An anti-odour finish keeps things fresher through long days.

Built to move

An athletic ergonomic pattern and flat-lock seam construction let the shirt fit close without chafing, whether you are on the range, on the site or training. The four-way stretch knit flexes with every reach, crouch and sprint.

Ready for your loadout

Loop patch panels on each sleeve let you add morale patches, ID or flags. Wear the Sigurd on its own, under a plate carrier, or as the foundation of a layering system. Discover more 5.11 tactical clothing at Platoon Stores, Kent’s only authorised 5.11 Tactical retailer.

Frequently asked questions

What does Cryo-Tac actually do?

Cryo-Tac is 5.11's cool-touch treatment on the stretch mesh knit. It gives the fabric a cool feel against the skin and works with the moisture-wicking finish to help regulate temperature during exertion.

Can I wear it under a plate carrier?

Yes. The Sigurd is designed as a performance base layer with a close athletic fit and flat-lock seams, so it sits smoothly under a plate carrier or body armour without bunching.

Does the fabric stretch?

It does. The 78% nylon / 22% elastane knit provides four-way stretch and an ergonomic pattern, so it moves with you during dynamic activity.

Will it help with odour on long days?

Yes. An anti-odour finish plus moisture-wicking helps keep the shirt fresher through extended wear, training or multi-day use.

What are the panels on the sleeves for?

Each sleeve has a loop patch panel, letting you attach morale patches, ID or flags to personalise your kit.
