A tank in a different weight class. The Heavy Rib Tank is knitted from 430g of 95% cotton and 5% elastane, ribbed on both faces so it is soft against the skin either way round and holds its structure instead of collapsing after a wash. The rib runs vertically through the whole body. The cut is close — a wide crew neck, deep armholes and a straight hem that sits at the hip. Wear it on its own or as a base layer under an open overshirt or the Ruins Washed Zip Vest. ✓ 95% cotton / 5% elastane, 430g — double-faced rib, soft both sides. ✓ Holds its shape and colour through repeated washing. ✓ Wide crew neck, deep armhole, straight hem. ✓ Solid colours throughout — no graphics, no branding. Eight colourways: Black, White, Grey, Dark Grey, Navy Blue, Forest Green, Brown and Red. This one is cut close, and the measurements below are taken with the rib at rest. The fabric has real stretch, so it will sit wider on the body than the numbers suggest. If you want it loose rather than fitted, take a size up.
