Your new go‑to shirt for work, team events, or casual wear is the Gildan H400 Unisex Hammer™ Long Sleeve. With a classic fit, rib‑cuffed sleeves and a soft, ring‑spun cotton feel, it delivers comfort that lasts all day. Choose from four versatile colors and sizes from S up to 4XL, and enjoy low minimum orders—screen printing starts at just 24 pieces, while DTF and dye‑sublimation accept even smaller runs.

OEKO‑TX certified low‑impact dyes and Better Cotton sourcing make the shirt a sustainable choice for environmentally‑aware brands. Whether you need a bold screen‑printed logo, a full‑color DTF graphic, or a photo‑rich sublimation design, the Hammer’s tight stitch density ensures crisp, lasting results. Ideal for businesses, schools, sports teams, and promotional events, this shirt balances professional appearance with everyday comfort.
