Gildan H400 - Hammer™ Unisex Long-Sleeve T-Shirt - Chambray

The Gildan H400 Hammer is a 6 oz 100% combed ring-spun cotton unisex long-sleeve tee built for decorated apparel programs that need a heavier-weight blank with a cleaner print surface than standard open-end cotton. The Hammer sits a step above the Heavy Cotton G500 in yarn quality: ring-spun and combed cotton aligns the fibers tightly during spinning, producing a higher stitch density face that gives screen printers sharper halftone reproduction and DTG operators a smoother pre-treat bed than the coarser open-end construction in the G500. At 6 oz, it is also heavier than most comparable ring-spun long-sleeve blanks, which keeps the garment stable on the platen under the squeegee and reduces the stretching that undermines registration on lighter jersey bodies.

For DTF transfer, the 100% combed ring-spun cotton surface on standard solid colorways bonds reliably at standard time and temperature. The heavier 6 oz body stays flat under the press without the stretch-and-creep common on lighter 4-4.5 oz long-sleeve jerseys. For screen printing, the high stitch density face holds plastisol and water-based ink with less dot gain than open-end cotton, so halftone detail and fine text that would spread on the G500 prints crisper here. Graphite Heather is 50/50 cotton/polyester and carries dye migration risk at high cure temperatures: use a low-bleed ink set and reduce cure temp, or run a poly-block underbase on dark-coloured art on that colorway. Sport Grey is 90/10 cotton/black polyester and prints nearly like a solid cotton but should receive a light poly-block underbase for saturated ink on dark artwork. For DTG, the combed ring-spun face takes pre-treatment more evenly than open-end cotton, producing a more consistent ink lay on coloured grounds. For embroidery, the 6 oz body provides enough density for left-chest, full-front, and sleeve placements without additional backing on most hoops. The rib cuffs are knitted separately and are not a flat print surface; keep screen-print and transfer placement on the body, clear of the cuff seam.

For shops running repeat school, corporate, or event long-sleeve programs, the H400 offers color and sizing consistency between production runs that is characteristic of Gildan's volume manufacturing. The ring-spun construction holds sizing grades more consistently across washes than lower-twist open-end yarn, which matters when a repeat customer reorders the following season and expects the same fit as their first order. The H400 is available by the piece or by the case (dozen or multi-dozen case packs); ordering by the case reduces per-unit cost and keeps decorated-apparel programs cost-efficient at scale. TheClothingSpace stocks the H400 at wholesale pricing with bulk discounts that increase with case and unit quantity, among the lowest prices online for this style, with fast US shipping on stocked colors.
