    Not saving my thighs

    The band on these shorts feels comfortable, and the longer ones in the same size fit great, so I don't think I got the wrong size, but these cut into my thighs enough to have pretty obvious bulge above and below the bottom hem. And after wearing them for not long at all, they had slid up to essentially just be a normal pair of briefs.

    Absolutely awful!

    These were recommended by an influencer and obviously I was influenced. They are wayyyy too expensive for what you get!! They are too thin and stretch out horribly!! No I would NOT recommend these 4” Sortie Thigh Saver! For reference I’m 5’3” 125lbs and bought the small

    Legs ride up

    Nice fabric, good fit, very comfortable but the legs ride up, so I’m not sure I will wear them again.

    They Ride Up

    This was my first time buying thigh savers from Knix and usually I'm really impressed with how well things fit, but these were a huge disappointment. The top rolls down and the the inner thigh immediately sucks in so you have zero coverage between your thighs. They were also quite tight, more compressive than I was expecting.

    Too thin

    Fabric too thin, if you have a tummy it rolls right under without moving.

    feels so good.

    I love these new (for me) shortie thigh savers. I have purchased many of the thigh savers over the years,

    I still have some from 2years ago. These I only wear around the house as they are getting old.

    What I have noticed about the thigh saver this year, is that they are better reinforced in the crutch.

    The reinforcement the a much better design feature. Oh the fit is great.

    I will purchase more of these little wonders in the future.

    Must have!

    I rarely ever write reviews, but these shorts are a MUST for summer. I’m so upset with myself for not getting them sooner.

    No ragrets!

    I love these shorts! They don’t roll down and the legs don’t roll up! So comfortable I barely feel them on.

    Love!!

    Tried out 1 pair of these 4” thigh savers during the annual sale on July. Was slightly skeptical as all my other thigh shorts (Knix and other brands) are longer, probably about 6”. I am now converted to the 4” length. I love that they’re short enough for summer dresses and are not hot. Slightly compressive, which is always good. I would love to see these in a light leakproof version! I will be stocking up on these!
