These underwear are convenient to wear and a great back up for heavier days. They are relatively comfy and for the most part, do the job. Unfortunately the quality is not there- I have 2 pairs that are about 6 months old and the seam is coming undone (see pictures) in both pairs. I have followed all the instructions for care and the underwear have stretched out SO MUCH. Still, I must of liked them enough to buy more, because I did. The experience in the store was not good...I stood at the till for quite a while before the two cashiers that were casually chatting checked me out. It was awkward and I didn't leave with a good feeling. I now own 5 pairs of knix underwear- and well they aren't the worst, they certainly aren't the best either. I won't be buying another pair of these- there is other brands that use cotton and seem to be the same price point This lyrca/polester blend is cheap and coming apart. My advice to others- look at other brands around a similar price point and different materials.
