The Wonder Looper Double Heavyweight French Terry Sweatpants take loungewear into entirely new territory, built from one of the heaviest knits available today. Cut with a modern straight-leg silhouette, they balance serious fabric weight with everyday comfort, offering a structured yet relaxed feel.
Crafted in Japan from 100% cotton French terry, the fabric is knitted in Wakayama on low-gauge 10G circular knitting machines. At 876gsm, or 25.8oz per square yard, it is roughly twice the weight of a standard heavyweight knit, with an irregular exterior texture and large, soft loops on the inside. The interior is lightly brushed for a half-fleece effect, giving a fuller, softer hand while retaining the distinctive terry loop texture. Rinse-washing and pre-shrinking help set the fabric and minimise further shrinkage.
