It was just yesterday when size? previewed its upcoming Puma XS850 collaboration from its "Wilderness" pack. Joining the XS850 "Innercity" will be the R698 "Sahara," which the UK-based retailer recently teased on Twitter.

Unlike the preview of the "Innercity," the "Sahara" is much more visible. Based on the early look, it appears the R698 will be outfitted in a sand-colored suede upper with sky blue lining and a speckled midsole. According to size?, a full look of the "Wilderness" pack will be offered this Sunday and the release will soon follow on Saturday, June 21.
