Our custom knit French Terry fabric clocks in at 400gsm and is cut and sewn for us in Canada. Unlike our standard heavyweight fleece which is brushed on the underside, this is a french terry with a towel-like feel where the yarn loops are left intact. We've removed the front kangaroo pocket and replaced it with hidden gusset pockets along the side seams for added functionality and a cleaner look. SIZING: Please note that with the garment dye that's been done, all shrinkage has been removed. So long as they are washed in cold water and hang dried, they will not shrink any further.
