Our soft four-way stretch fabric stretches in both directions (length and width) and recovers by gently springing back when pressure isn’t applied in any direction. This makes the modal fabric an ideal choice for basic activities such as walking, running, biking or even during more strenuous activities such as working out at the gym, hiking or rock climbing. With the 4-way stretch fabric everything stays in place, including your junk, without getting pinched or pulled on. And with the incredibly soft 95% modal 5% spandex fabric it feels as though you’ve got nothing on.
