Flex underwear that fits with your every move
Meet flex underwear: designed to stretch when you stretch, stay put when you move, and feel good all day long. These are base layers that don’t pinch, twist, or distract, just soft, flexible pieces built for everyday comfort with zero compromise.
Everyday ease with next-level stretch
From mid-rise briefs to barely-there cuts, this underwear adapts to you. The fit is snug without being restrictive, with flat seams and wide waistbands that don’t dig in. Whether you’re working, relaxing, or on the go, it keeps its shape and holds its comfort. Complete the set with one of our flex cotton bras for a no-fuss match that supports you from the inside out.
Each pair is crafted from soft, stretch-blend cotton that balances breathability with structure. Sometimes organic, sometimes not — always thoughtfully sourced. Learn more about how we pick our materials to support your routine from the ground up.
Flex your full foundation
This isn’t just a single piece. It’s part of a full system made for comfort and ease. Mix and match with pieces from the flex cotton collection, or layer up with simple go-to pieces from our flex cotton tops. Soft, stretchy, and stays exactly where it should — your new daily default.
