1. A fabric comprising:
a first yarn comprising a fiber blend of modal and polyester, the modal being present in the fiber blend in an amount between about 5% and about 25% by weight, the polyester being present in the fiber blend in an amount between about 75% and about 95% by weight, the first yarn forming a bottom layer of the fabric that removes perspiration from a wearer by contact with the wearer's skin in use;
a second yarn comprising spandex, the second yarn forming a middle layer of the fabric; and
a third yarn consisting of 100% polyester, the third yarn forming a top outer layer of the fabric to evaporate the perspiration removed from the wearer's skin,
wherein the polyester in the fiber blend has a cross-section that creates a plurality of spaces along the length of the first yarn that facilitate a capillary action, wherein the first yarn comprises between about 45% and about 75% by weight of the fabric, and wherein the third yarn comprises between about 20% and about 50% by weight of the fabric, and wherein
the fabric has a water vapour resistance in the range 2.071-2.58 (m2·Pa)/W when tested according to ISO 11092:2014, drying time in the range 145.9-192 minutes when tested according to (AATCC) 199-2013, and a vertical wicking rate in the range 4.3-5.7 (inches/10 minutes) when tested according to (AATCC) 197, Option B.
