    You won’t be disappointed if you buy these .

    Longtime wearer of 9” boxer briefs. Mostly driven by comfort and the desire of a no line look. Even before they made them for women. I think I bought my first pair of these undies when I bought a Knix support bra recommended in runners’ magazine. I liked the bra but I loved the Thigh Savers. Hard to describe the material. Light but finely woven. Offer a little compression and absolutely do not roll up. They have become my go to travel underwear because they are super comfortable, absorb sweat and odor and are easy to wash and quick to dry.

    They are on the pricier side so I wash them in a bra bag and dry low or hang. I don’t have enough of a collection to wear everyday but I will be watching for sales.

    Thigh Savers

    These 6 inch thigh savers fit true to size and do not roll down or the leg ride up. I have a fuller waist and they stay put. Buy your correct size for your hips and they should fit well

    Invisible and barely there!

    I will always grab these when i'm wearing a satin or clingy skirt or dress. They really are invisible, and feel so smooth and light. I'm 5' 6" and find the 6" length perfect.

    The gusset doesn't feel leakproof, but it makes me feel more confident knowing it's there when i'm wearing delicate fabrics or a short skirt.

    Great at first but stretched out a lot!

    I was in love with these for my first 3-4 wears but now they are so stretched out and fall down from the waist easily. I’m typically an XXL and sized down to a L too but I would have purchased a M had I know just how loose they would get. Disappointing for such a great product initially.

    Almost perfect

    The thigh savers are comfortable, don’t creep up and generally do as advertised. I would like them slightly more look proof.
