    Baseball practice ready

    Good for long batting sessions. Could use a slightly stretchier waistband.

    Kayak tested

    The comfort is so consistent that I forget I'm wearing them. Whether running errands or relaxing at home, they provide perfect all-day ease.

    Finally found underwear that stays put all day long

    Burpee championFifty straight burpees and no wedgies. The four-way stretch moves with my body during explosive movements.

    Stays comfortable during sports

    Perfect for active lifestyles - they stay put during workouts while keeping me dry. The fabric moves with my body without restriction. The waistband doesn't dig in even during intense exercise. They wash well and dry quickly. My only minor complaint is the legs could be slightly longer to prevent any riding up.

    The stitching never fails

    After losing weight, none of my old underwear fit properly. These have been perfect - they hug my new shape comfortably without being too tight. The fabric is soft and breathable, and they don't ride up or bunch like others I've tried. The waistband stays put without digging in, which is especially nice now that I'm more active. They've held up well through many washes while maintaining their shape. The price is steep but the quality and comfort make them worth it. My only suggestion would be to offer more color options in the smaller sizes, but that's a minor complaint considering how great they are otherwise.

    Stretches but never sags

    Perfect for active lifestyles - they stay put during workouts while keeping me dry. The fabric moves with my body without restriction. The waistband doesn't dig in even during intense exercise. They wash well and dry quickly. My only minor complaint is the legs could be slightly longer to prevent any riding up during certain activities.
