Super Looper Crew Neck Sweatshirt

Knit in Wakayama, Japan on century-old loopwheel machines, the Super Looper French Terry lives up to its name—with an ultra-plush interior full of irregular loops that feel like a high-end hotel towel, and a sleek outer face that plays it cool. At 446 GSM, it’s got real presence—weighty but breathable, cozy but clean-cut. (Curious what GSM means? Here’s a quick explainer.)

Details include a ribbed collar with a vintage V gusset, raglan sleeves for easy movement, and side panels for a hint of structure. Flat seams keep it all looking sharp. The fit is modern and athletic, built for repeat wear.

Made start to finish in Japan.
