    Love the band and the material

    I bought the grey pair because I loved the colour and the band but didn't want the boxer style. I was hesitant because I do prefer a brief style since I am a larger shaped body. French cut is not my thing. I was right I'm not a fan of the cut but WOULD LOVE this material and waist in a brief style. I will wear these ones obviously but would buy 20 pairs of they were in a brief cut. Perfect absorbance and placement for me. I just need more of my tummy covered.

    Very comfortable

    I like these underwear (I have a large/round butt) so a lot of underwear slide inwards, but these have enough coverage to stay put. I would say it is a "generous" cut. I wear a small size.

    These are on sale for a reason

    These look great and they seem like a great choice on first try, but I had issues with both colors: the black had the elastic separate from the body forming a hole on the 2nd wash (after the first wear; washed before wearing of course). The grey/taupe is pilling like crazy on the elastic; it's like the elastic is disintegrating. I'm glad I have other pairs to fall back on, but this was a total waste buying multiple pairs of these modal rib, which is unfortunate as they're so soft and comfortable.

    High Quality

    These are the best I have found — better than well known brand names. I especially like the fact that they come in French cut, which I haven’t been able to find elsewhere.

    Favorite Style

    My first purchase was the regular material style but the liners in those are not long enough and also don’t dry quickly when sweating. Then I bought the cotton but those don’t have as good odor control. These ribbed style is by far my favorite! The liner is longer with much more coverage and they are very comfortable and well made. Highly recommend this style.
