    Who knew Knix made amazing active wear

    I just purchased 2 complete outfits from knix to workout with in 2026! I absolutely love each and every piece. From these great shorts to the pursuit jacket the quality and fit are beyond my expectations at a reasonable price point! Thank you knix.

    Comfy & covered

    I feel much more confident wearing these shorts out and in the gym. It's leakproof, loose & flowy, and has the liner shorts underneath, so I don't worry about cameltoe or sweat/leaks ect.

    My fave short!

    I’ve bought other workout shorts from leading sports brands.. but the inside layer always rides up and leads to that painful leg rubbing. These are tight around the leg, comfortable around the waist, I love them so much I bought another pair. Highly recommend! The leak proof aspect is a major bonus.

    LOVE! Don’t ride up and no chafing

    These shorts do it all - these are the only shorts I run in during the summer. The waistband doesn’t fold over or slide, and the inner shorts stay in place with no chafing. Please make more colors!

    My absolute favourite

    Wear these for cardio and HIIT workouts. Never have to worry about LBL with these sweet shorts. They stay where I want them and hold onto my key in the thigh pocket. Just ordered a second pair.
