11oz Cotton Knit Crew Neck T-Shirt - White IHT-1600-WHTIHT 1600 Made from a heavyweight 11oz cotton knit fabric, this is far more than just a T shirt. Whether worn as a single layer or as a thermal undershirt, the soft, heavy weave offers enhanced comfort and durability, with the increased heat retention of the heavier fabric making these ideal for year round layering. Featuring a classic crew neck design with a ribbed collar and cuffs, youll be hard pushed to find a more heavy duty tee. Made in Japan
