I claim the ornamental design for a compression calf sleeve, as shown and described.
FIG. 1 is a perspective view of a compression calf sleeve, as worn on the leg of a user;
FIG. 2 is a front view of the compression calf sleeve;
FIG. 3 is a rear view of the compression calf sleeve;
FIG. 4 is a left side view of the compression calf sleeve; and,
FIG. 5 is a right side view of the compression calf sleeve.
The broken line showing of a human leg in FIG. 1 is for the purpose of showing enviroment which forms no part of the claimed design. The broken line showing of a front logo and rear seam are for the purpose of illustrating portions of the sleeve which form no part of the claimed design. The patterns on the sleeve represent claimed yarn and thread contrast.
