Quality products that provide ultimate comfort and excellent value for money. Side seam free makes it super comfortable and ideal for layering. Cotton interlock is a wonderful knit fabric. It is extremely soft and a little stretchy, perfect for under garments. It is warmer than cotton jersey or rib knit because it is a double knit construction, making it thicker and heavier than a single knit. And since it is combed ring-spun, it is super soft! Made with premium fibres for a luxury feel and durability. Perfect for use throughout the year. Ideal for everyday wear, for sports activities and for showing off those muscles in the gym! Carefully Designed in England.
