The Flat Head FN-TSH-003 Henley T-Shirt features a button-front placket that gives the collar its signature detail — offering a more relaxed, casual aesthetic than a standard crewneck while retaining The Flat Head's uncompromising attention to fabric and construction. The buttons serve both as a visual accent and a functional element: opened up, the placket improves airflow and comfort in warmer weather, making this a versatile piece across seasons.

The body is knit from the same heavyweight 9.3oz tubular jersey used across The Flat Head's popular THC T-shirt series. Produced through a high-density knitting technique known as "doze", the fabric is thick, structured, and remarkably resilient — with a hand feel and shape retention far superior to standard jersey. The tubular knit body has no side seams, eliminating the raised seam ridges that can cause irritation during long wear.

The placket buttons are vintage-style urea cat's-eye buttons — named for the small recess at their center that resembles a cat's eye. The recess protects the sewing thread from wear, ensuring buttons stay attached over years of use. Urea-resin buttons are heat- and impact-resistant — historically favored across military and workwear garments — and remain a hallmark of vintage-inspired construction today.

Construction details are finished with the same rigor as the fabric itself. The armholes and shoulder seams are sewn on a 1960s Union Special flatlock machine, using cotton thread for a refined, low-profile finish that eliminates seam bulk against the skin.

Fit Notes: This shirt fits small. Compared to most global American brands, a size 42 fits similarly to a standard American Large. As always, we strongly recommend checking our size chart and comparing it with your best-fitting shirt to find the perfect size.
