Three tanks, three different colours
The word pack makes people expect three of the same thing. One bag holds a white tank, a black tank and a brown tank, and no two of them match. So this is a three colour rotation, not a three week laundry buffer, and you cannot replace one when it wears out, because there is no single version to buy again. What the three do share is the cut and the knit, so the fit you learn from the first holds for the other two.
The binding is the opposite colour on every piece
White tank, black edge. Black tank, white edge. Brown tank, white edge. The binding runs the whole neckline, both armholes and up each strap, and it is a strip folded over the raw edge and stitched down, not a printed line, which is why it has a thickness you can feel. This is the one decision that makes the pack read as a set: three plain ribbed tanks in three colours would be three unrelated tops, and the reversed edge ties them together without printing anything on them.
Sweetheart in the listing, a sharp V in the photographs
The bullets say sweetheart collar, and so does the back end. A sweetheart neckline is two curves meeting at a rounded point and it is cut wide across the chest. What the photographs show is a straight sided V, apex low and narrow. The difference is not cosmetic. A sweetheart sits flat and hides a bra cup edge; a sharp V cuts lower in the centre and shows what is under it. Order for the V.
The back is a Y, not a T
Two thin straps leave the shoulders, travel inward and meet at one point between the shoulder blades, then a single short strap continues down. A classic racerback is a T: the straps meet higher and fan out into a wide panel. Here the panel is almost absent, so the back is open either side of the Y. Good for heat, bad for a bra with straps set wide, because both will show.
Ribbing runs across, not up and down
Look closely at any photograph and the lines are horizontal, a fine corrugation running around the body rather than along it. Horizontal rib is the more elastic direction, which is why this knit stretches over the chest and returns without bagging, and why the tank looks narrower off the body than it measures. It does not press flat either, so this is not a top to iron or one that stays crisp under a jacket.
The bullets say three sizes, the chart lists five
Five are on the chart and in the selector, extra small to extra large, bust 25.2 to 36.1 inches. The bullet list says three. The chart wins, and the variation data agrees, thirty combinations across six colour packs and five sizes. Only bust has numbers; waist and length are blank. Small and medium divide at 27.4 inches, medium and large at 29.6, measured on the bust. The knit gives, so take the smaller of two.
One colour pack, one size, on this page
This listing is the brown pack in small. Both selectors work, so the other twenty nine combinations exist and can be bought, each on its own page. What is not here is a single tank: three arrive together and are priced together. Worth knowing before comparing the number against a one piece listing, and the per unit figure under the price is the one to compare.
What it is not
Not a bra. No pad appears in the bullets, the attribute table has no padding field, and nothing in the photographs suggests a moulded cup, so treat it as a fitted tank and wear your own underneath. Not fully seamless either, whatever the title says: the body has no side seam, but the binding at every edge is sewn on. Not a long line, the hem ends above the navel, and the shoulder to hem figure reads 4.5 inches, which cannot be right for a garment covering the ribcage as these photographs show. Cold wash, inside out, and keep the white piece away from anything new and dark at first, because the first thing to go on a contrast edge is the white.
