Wonder Looper’s Triple Heavyweight Crew Neck Tsuriami T-Shirt is the kind of piece that stops you in your tracks. Built from a massive 593GSM jersey, it’s nearly three times the density of a standard heavyweight tee, but what makes it truly special is how that weight is created. The fabric is knit on century-old tsuriami machines in Wakayama, moving at a crawl - barely a meter an hour - to produce an incredibly dense, beautifully textured jersey that modern machinery just can’t replicate. The American Texas cotton brings natural slub and lift to the surface, giving the shirt a rugged, tactile feel that settles in and softens as it’s worn. With a classic crew neck, clean silhouette, and that unmistakable Wonder Looper structure, this is a tee built to last decades, not seasons, and to break in with the kind of character only slow-made knitwear can deliver. 593GSM / 17.5oz jersey 100% Texas cotton Tsuriami knit Triple heavyweight construction Crew neck Made in Japan Size Length Chest Shoulder Sleeve XS 24.80 18.50 17.00 7.10 S 26.00 19.70 17.70 7.80 M 27.10 20.90 18.50 8.20 L 28.30 22.00 19.70 8.60 XL 29.00 23.60 20.90 9.00 XXL 30.00 25.20 22.00 9.40 table { width: 100%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: center; } th { background-color: #f2f2f2; } A variance of +/-.5" is within tolerance.  Fit Notes: Shop owner Tommy is wearing a size large this round. That's his standard wonder looper size, which is what we recommend you stick with. It's a very hardy shirt, so if you're on the fence at all, size up. Tommy is our standard fit model at 5'9" 165lbs with a 40" chest.
