Tank sizing is more variable than tee sizing because the cuts span everything from form-fitting ribbed vests to roomy basketball jerseys. Here's the breakdown by family.
Ribbed cotton vests (OG Alcatraz Ribbed Vest).Form-fitting by design — sit close to the body, designed for layering.Stay TTS for the standard slim base-layer fit. Sizing up makes the rib lose its visual texture and the layering function fail.
Waffle tanks (4 Starz, 5 Starz, Guerillaz Waffle Knit).Slightly looser than the ribbed vests but still closer-cut than a basketball jersey.Stay TTS for the standard fit.Size up oneif you want the tank to drape further past the cargo waistband.
Graphic jerseys vintage big-logo tanks.Roomier athletic cut, drape further from the body.Stay TTS even if you usually size up on athletic wear — the cut is already relaxed. Sizing up here pushes the tank into "oversized t-shirt with the sleeves cut off" territory, which loses the tank silhouette entirely.
Cropped tanks women's fit vests.Cut shorter through the body, slightly slimmer through the chest. For the standard Corteiz cropped fit:stay TTS. For a women's fit specifically:size down one or two depending on desired tightness — these are sold in men's streetwear sizing, so a women's M typically corresponds to a Corteiz S or XS.
Unisex sizing notes.Across all five families, the tank archive is the most flexibly unisex category in the Corteiz wardrobe. The ribbed vest in Triple Black or Black/White works on any frame. The cropped tanks are explicitly women's-leaning by silhouette. The graphic jerseys read unisex by athletic-cut convention.
