Description

The Sport-Tek ST284 Super Heavyweight Full-Zip Sweatshirt is a heavy, substantial full zip built for premium warmth and clean, professional branding. It is made from a 12 ounce cross grain 80/20 ring spun combed cotton and polyester with a 100% ring spun combed cotton face, so the all cotton face gives designs a smooth, even surface for sharp decoration while the dense cross grain construction adds real weight and structure. The Super Heavyweight name speaks to the exceptional heft of the fabric, and at 12 ounces it carries genuine insulation that holds its shape rather than feeling flimsy. That premium, durable character makes the ST284 a strong choice for workwear, corporate programs, teams, streetwear, and everyday cold weather layering.

The construction pairs a substantial fleece with premium hardware and details. A cadet collar stands up for a sharp, athletic neckline, and an antique nickel finished zipper runs the full length for dependable hardware with a classic, vintage inspired detail. Twill taped neck gives a durable, comfortable interior finish, front slash pockets keep belongings close with a clean, angled entry, and 2x2 rib knit cuffs, hem, and side gussets with spandex hold their shape and stretch for comfortable movement. A tag free label keeps the interior smooth and comfortable against the skin.
