The knit uses four separate yarns which collectively work together to produce enhanced cooling. Knits can include warp knit spacer and circular knit spacer materials. Various finishing methods may also be employed to enhance the cooling power of the fabric. ## Claims ### Claim 1 A two-sided absorbing and cooling textile, comprising: an absorbent side adapted to absorb moisture from a skin surface and including a first yarn and a second yarn, a pile height of the absorbent side being greater than 0.2 millimeter; and a cooling side adapted to transport the absorbed moisture from the absorbent side to expose the absorbed moisture to the cooling side for evaporation, the cooling side including the first yarn, the second yarn, an evaporative cooling yarn, and an elastomeric yarn. ### Claim 2 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the two-sided absorbing and cooling textile is adapted to cool the skin surface on the cooling side by up to 20° F. and up to 40° F. over core body temperature when the two-sided absorbing and cooling textile is wetted. ### Claim 3 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the two-sided absorbing and cooling textile is adapted to cool the skin surface for a period of over 4 hours when wetted. ### Claim 4 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the two-sided absorbing and cooling textile is constructed using a warp knit spacer construction. ### Claim 5 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the two-sided absorbing and cooling textile is constructed using a warp knit spacer machine. ### Claim 6 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the first yarn includes microdenier, microfiber, conjugated bi-component poly/nylon, cooling Polyester, and/or cooling nylon. ### Claim 7 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the second yarn includes microdenier, microfiber, conjugated bi-component poly/nylon, cooling polyester, and/or cooling nylon. ### Claim 8 (depends on 6) The two-sided absorbing and cooling textile of claim 6, wherein the second yarn includes microdenier, microfiber, conjugated bi-component poly/nylon, cooling polyester, and/or cooling nylon. ### Claim 9 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the evaporative cooling yarn includes an evaporative and UV-protective yarn. ### Claim 10 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the two-sided absorbing and cooling textile has a weight of 100-600 g/m2. ### Claim 11 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the elastomeric yarn includes spandex. ### Claim 12 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the absorbent side has a pile height of 2-3 mm. ### Claim 13 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the absorbent side has a pile height of 0.5-10 mm. ### Claim 14 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein a Q-Max of the cooling side when wetted is at least twice a Q-Max of the cooling side when dry. ### Claim 15 (depends on 14) The two-sided absorbing and cooling textile of claim 14, wherein the Q-Max of the cooling side when wetted is at least twice a Q-Max of the absorbent side when wetted. ### Claim 16 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the first yarn and the second yarn are located on separate but adjacent knitting bars during construction of the two-sided absorbing and cooling textile. ### Claim 17 (depends on 1) The two-sided absorbing and cooling textile of claim 1, wherein the pile height varies across a surface of the absorbent side. ### Claim 18 (depends on 1) The two-sided absorbing and cooling textile of claim 1, further comprising minerals and/or particles embedded in at least one of the yarns adapted to transport and evaporate moisture from the skin surface. ### Claim 19 A garment adapted to be worn next to skin of a user, comprising: a two-sided absorbing and cooling textile, including: an absorbent side adapted to absorb moisture from a surface of the skin and including a first yarn and a second yarn, a pile height of the absorbent side being greater than 0.2 millimeter; and a cooling side adapted to transport the absorbed moisture from the absorbent side to expose the absorbed moisture to the cooling side for evaporation, the cooling side including the first yarn, the second yarn, an evaporative cooling yarn, and an elastomeric yarn. ### Claim 20 (depends on 18) The garment according to claim 18, wherein the garment is arranged as a shirt, pants, shorts, a headband, a towel, and/or a hat.
