What our customers are saying
Customers say these cotton high-rise underwear are extremely comfortable and provide reliable leak protection for bladder leaks and periods. Many find the cotton fabric soft and breathable, especially in warm weather. Users appreciate the secure fit and confidence they provide for daily activities like sneezing, coughing, or exercise. However, some customers report issues with the floating gusset design, describing it as bulky, uncomfortable, or prone to shifting. A few mention durability concerns with holes developing after washing. While most praise the comfort and effectiveness, some find the waistband tight or notice the design creates visible lines under clothing.

    Leakproof Cotton High Rise

    A bit bulky probably bc they are cotton but may work better for heat in summer 🤷🏼‍♀️

    Hey Jocelyn,

    Thanks for the review! Cotton can feel a bit bulkier but you're right - it's great for staying cool in the summer heat!

    Nice Fabric Option

    I do like having a cotton fabric option for period underwear, but I find that I notice the back seam on these way more than other Knix underwear. Overall these are great on my skin, but I understand why they are last call.

    Cozy, run small

    These are so soft and cozy. I needed to size up 2x. The gusset is small, it doesn't run all the way up like others.

    Toronto Knix Underwear - Avoids Wet Marks On Clothes

    Helps adsorb perspiration from apron belly and keeps me calm while getting to a bathroom during sudden urinary urgency. Would appreciate more light colour choices to wear under summer clothes.
