New Item - The Mountain T-Shirt with Guinea Pig Face Kids design by The Mountain. This heavyweight 100% Cotton T-Shirt will last you for years and features an over-sized relaxed fit, with reinforced double-stitching on all seams. Available in S to XL sizes. After just one wash you will not know where the print ends and the shirt begins. Our unique printing process actually pulls the dye color out of the shirt and leaves the ink color behind, essentially dyeing the cotton with the ink. After dyeing they are washed and dried, so they arrive to you comfortable, pre-shrunk & ready to wear.
