Familiarity: I've put it through the wringer Fit: True to size Size Bought Medium Height 5` 5\" Weight 130 lbsI used to have awesome tye-dyed cotton undies made from T-shirt material. So since I cannot get those undies anymore, I looked at the Patagonia Active Hipster Briefs. Not cotton, not tye-dyed t-shirt material, but dang if they are not just as comfy if not more so! My hubby said the stripes looked great on me, so I bought a few more... Thanks Patagonia for some awesome undies!
