We've made our products even better. With our improved fit, we've upgraded our sizes to give you the most accurate fit for your body!

To find the best fit, measure your hips at their widest point and compare them to this chart. If your measurements fall between two sizes, we recommend opting for the smaller size.

Say goodbye to guesswork and hello to a flawless fit that moves with you and your flow!

It’s ok to have questions.

  • Yes! All our products featuring ComfortFit offer the same all-day protection you rely on. We’ve kept the TriTech Performance you know to keep you dry and secure, but we’ve refined the fit to make it even more comfortable and less bulky. It’s all the protection, but now it’s more comfortable than ever! 🚀

  • ComfortFit is all about upgraded fit, crafted from customer feedback to deliver full-day period protection with improved comfort and no bulk. Some of our products have been upgraded with ComfortFit, which means you’ll get a more precise fit to your unique body shape. With this upgrade comes a refined size guide, so it’s important to check the new size guide when selecting your ComfortFit washable pants to ensure you get the perfect match!

  • As the new ComfortFit upgrade comes with an improved fit, we recommend measuring your hips again and comparing them to the chart above.

  • Given the enhanced fit, it's best to opt for the smaller size if you're in between.

  • ComfortFit has been specifically designed to be more tailored to your body. With slimline edges and a flexible, comfortable fit, it moves with you and reduces bulk, giving you a snug yet breathable feel. It’s all about comfort without compromising on
    performance, so that you can feel confident all day long.

  • Absolutely! Like all of our washable period underwear, ComfortFit is designed to be machine washable and reusable, just like the rest of our products. Just follow the care instructions, and your ComfortFit will continue to provide you with comfort and reliable protection for 50+ washes*.

    *Up to 25+ washes for Sleepwear range.

  • To keep your ComfortFit underwear performing at its best, rinse it in cold water, then wash it at 40°C with the rest of your laundry. For added protection, we recommend using our laundry bag to prevent wear and tear. Avoid fabric softeners or bleach as they can affect the materials and performance.  After
    washing, simply hang it to dry— just wear, wash and reuse!

    For more detailed care instructions, you can refer to our full care guide.

  • We all know sleep is the most important time to recharge, so comfort is key—especially when you're on your period! That’s why we’ve upgraded our sleepwear range to feature our new improved fit, making sure you get a leak-free, comfortable night. Available in two of our best-selling styles, these sleepwear options provide the protection you need, so you can sleep soundly and wake up ready to take on the day. 💪
