Florence Marine X Airtex Longsleeve Shirt Black

The Florence Marine Airtex Longsleeve Shirt is a high-output utility layer designed for training, movement, and extended use across changing conditions. Positioned as the brand’s most technical utility top, it combines a lightweight build with a performance-focused fabric structure that supports breathability, mobility, and day-long comfort. The result is a long sleeve that wears with the clean look of a T-shirt, while functioning more like technical equipment.

This updated AIRTEX construction is described as lighter and more breathable than its predecessor, making it well suited to activities where heat management and airflow matter. The covert mesh structure improves ventilation without giving the shirt an overtly technical appearance, which keeps it versatile across sport and everyday use. For running, hiking, biking, sailing, yoga, crosstraining, or other high-output sessions, the balance of low weight and breathability makes practical sense.

The shirt is built with engineered stretch, allowing it to move more naturally during repetitive or dynamic motion. An antimicrobial treatment helps maintain freshness during demanding activity, while UPF 30+ adds an extra layer of sun protection for use in exposed environments. Florence Marine also includes a reflective "EQUIPMENT MODERN" heat transfer detail, adding visibility without changing the clean overall design.

Material choice is equally considered. The shirt is made from 100% recycled polyester and is produced with mostly recycled materials, aligning technical performance with a lower-impact fabric approach. A yellow utility locker loop is added for easy hanging and line drying, a small but useful detail that supports daily use and garment longevity. The fabric is also OEKO-TEX® certified.

Fit is true to size, though it runs slightly smaller than a standard T-shirt. If a looser fit is preferred, sizing up is recommended. For users looking for a refined long sleeve performance layer with a clean profile, lightweight feel, and strong breathability, the Airtex Longsleeve Shirt is a focused and capable option.
