Gildan Ultra Cotton Unisex T-Shirt . Ultra describes the entire experience of wearing a Gildan Ultra Cotton t-shirt. The first thing you’ll notice is the impressive heft of the fabric. At 200gsm, it is Gildan’s most substantial tee – making it a natural for demanding work and enthusiastic play. A taped neck and shoulders amp up the durability even more, and a giant colour palette assures you’ll find the perfect hue. Washing Instructions: Machine wash 30°. Do not bleach. Tumble dry low heat. Iron at low temp and inside out. Don't iron print. Do not dry clean.
