Discover unparalleled warmth and exceptional craftsmanship with the Double Heavyweight French Terry Sweatpants from Wonder Looper, crafted from a substantial 876gsm (25.8oz per square yard) fabric. Designed and produced with precision in Wakayama, Japan, these sweatpants are more than just apparel—they’re a tribute to Japanese artistry and meticulous attention to detail.

With a density twice that of typical heavyweight knits, these sweatpants provide outstanding warmth and comfort for cooler days and nights. Made from premium French terry on low-gauge (10G) circular knitting machines, they feature a unique, textured surface, while the plush loops on the interior offer ultimate coziness against your skin. They feature a modern straight leg fit, complete with a drawstring elastic waistband, front slash pockets, and a rear patch pocket. The ribbed side panels offer flexibility and a sleek, stylish appearance. Expertly crafted in Japan ensuring superior quality.

Fit Notes: Despite being a Japanese brand, we find the sizing of Wonder Looper garments to be more Western than Japanese. If you usually wear a size M in American pants, you'll find a suitable fit with this piece in size M. However, as always, we recommend consulting our size chart for the perfect fit.
