Florence Marine X Airtex Longsleeve Shirt Heather Vintage Khaki

The Florence Marine X Airtex Longsleeve Shirt is a high-output utility top designed for demanding movement across land and water. Built as the brand’s most technical utility layer, it combines a streamlined long sleeve silhouette with a fabric platform focused on breathability, mobility, and day-long comfort. In Heather Vintage Khaki, it delivers a clean, understated look while maintaining a performance-first construction.

This shirt is made from 100% recycled polyester and uses the next generation of AIRTEX, a material developed to be lighter and more breathable than its predecessor. The result is a baselayer-style top that supports sustained effort in changing conditions, whether used on its own or as part of a layered system. The covert mesh construction gives it the appearance of a standard tee-inspired long sleeve, while delivering the ventilation and technical function expected from dedicated equipment.

Engineered stretch helps the shirt move naturally through active use, making it well suited to running, sailing, hiking, biking, hunting, yoga, and cross-training. An antimicrobial treatment helps maintain freshness during repeated wear and high-output sessions, while UPF 30+ protection adds an extra layer of coverage for long days exposed to sun.

Florence Marine X keeps the detailing practical. A reflective “EQUIPMENT MODERN” heat transfer adds low-profile visibility, and the yellow utility locker loop makes it easy to hang the garment to dry, helping extend its lifespan between sessions. The fabric is also OEKO-TEX® certified, and the overall construction is made with mostly recycled materials, reinforcing a more considered material approach without compromising performance.

Fit is true to size, though slightly smaller than a standard T-shirt. Those looking for a more relaxed fit should consider sizing up. For users who need a lightweight long sleeve that balances technical breathability, stretch, and a clean everyday appearance, the Airtex Longsleeve Shirt is a precise and highly usable option.
