Hoshiba x Fruit of the Loom’s "Luxury Pack T Relax Fit" Rebuilds the Everyday T-Shirt From the Seam Up

The Hoshiba x Fruit of the Loom Luxury Pack T “Relax Fit” is the second installment in fashion director Yoshimasa Hoshiba’s ongoing Pack T collaboration with Fruit of the Loom, and where the original pursued a precise, body-skimming fit, this iteration sets its sights on a different kind of precision: the architecture of ease.

The fabric specification carries over unchanged from the first edition, and that continuity is deliberate. The T-shirt is built from 100% Supima cotton, a variety accounting for roughly one percent of global cotton production, spun into a 50-count single-yarn and knitted into a 6.3oz heavyweight smooth jersey. The result is a fabric with a matte sheen and a hand-feel Hoshiba describes as approaching cashmere in its softness, with enough body weight to stay opaque when worn alone and resist the kind of draping that reads as sloppy rather than relaxed.

The neckline is one of the more considered details in the construction. Rather than the standard ribbed collar found on most T-shirts, the Relax Fit uses the same smooth jersey as the body, sewn with minimal visible seaming. The tradeoff is deliberate: no polyurethane or elastic content in the neck means a cleaner, more elevated drape, closer to a dress shirt’s collar band than a casual crew. Care instructions flag that the neckline requires reshaping after washing, a fair exchange for the absence of the ribbed bulk that typically prevents a T-shirt from sitting neatly under tailoring.

Where the construction story gets more specific is in the body construction and seam method. Most T-shirts use a tubular (丸胴, marudō) body, which introduces a diagonal twist in the fabric after repeated washing, a phenomenon known in Japanese manufacturing as sha-kō. The Relax Fit uses a side-seam construction instead, which eliminates that post-wash skew and preserves the silhouette’s line over time. Along the side seams and underarm, Hoshiba introduced a proprietary finish called the “Hoshiba Binder,” described in the source as a world-first application of the fell seam technique used in dress shirts, adapted to knit fabric. The goal is seam stability: eliminating the rolling and twisting at the stitch line that is common in stretch jersey construction and which, over time, undermines the lay of the garment.

The silhouette itself was rebuilt from scratch rather than graded up from the original. Hoshiba notes that sales data from the first collaboration revealed a split between buyers choosing fitted sizes and those sizing up for room, which prompted a purpose-built relaxed option. The shoulder slope was re-angled so that the seam sits at the natural shoulder point rather than dropping, keeping the silhouette structured when layered under a jacket or blouson. Stitch width and stitch count at the sleeve hem and bottom hem were also individually calibrated to preserve the fabric’s texture rather than compress it. Brand and care labeling is handled via heat transfer print rather than woven tags, removing the tactile irritation common in heavier-weight jersey constructions.

The set is packaged across three colorways, White, Black, and Navy, each finished with what the source describes as refined dyeing adjustments to achieve depth and elegance rather than flat base-color saturation.
