High-quality fabrics and careful workmanship for unique comfort

To ensure that your size 45 shirt not only looks good, but is also comfortable to wear all day long, materials and workmanship play a decisive role. Fine cotton feels particularly soft against the skin and ensures optimum breathability. Fine linen fabrics give the shirt with collar size 45 a light, airy texture - ideal for warmer days. But it's not just the fabric quality that counts - precise workmanship is also crucial. Clean seams, collars that hold their shape and hard-wearing button plackets guarantee that your shirt will retain its shape and elegance even after frequent wear and washing. Particularly practical: non-iron men's shirts that smooth out almost automatically after washing and make your everyday life easier. Find your new casual or business shirt in size 45 at KAUF, which not only feels comfortable but also impresses with its long-lasting quality - for a well-groomed and stylish appearance at all times.

If you prefer a classic, straight cut, a regular fit shirt in size 45 offers a comfortable width that combines freedom of movement with timeless elegance. A discreet waistline on modern fit shirts with a collar size 45 ensures a balanced silhouette that is slightly figure-hugging but still leaves enough room for comfort. For those who prefer a close fit, Slim Fit men's shirts offer a modern, dynamic look that emphasises a slim line. For men who appreciate a particularly relaxed fit, Libero Fit men's shirts offer a loose cut with more width in the chest and waist area.

Sophisticated details for even more comfort

It's not just the fit, high-quality fabric and excellent workmanship for which KAUF shirts have been known for over 100 years that make the difference - it's the well thought-out details and special extras. Discreetly integrated into the shirt behind the breast pocket, the safety pocket, for example, offers you a discreet way to store your credit cards or ID cards. You will benefit from this clever detail, especially in hectic everyday life or when travelling: Not only are your most important documents safely stored, they also remain within easy reach at all times. While well thought-out functions such as the safety pocket make everyday life easier, some size 45 shirts with a jojoba oil finish offer a particularly pleasant feel on the skin. This finish takes the already high level of comfort to a new level - especially for men with sensitive skin.
