It's stretchy but doesn't contain any elastan! That's the point of the interlock structure. This fabric is Prepared for Printing: it is not finished with softeners or other products that could hamper the printing process. Still, this offwhite fabric feels soft and like every interlock its extensibility gives the wearer freedom of movement. With a weight of 220 gr/m2 it drapes nicely.
The interlock doesn't curl, which makes it easy to process. Because of these properties the fabric is used mostly for t-shirts, underwear, sportswear, casual wear and nightwear.
