Best Squat-proof Leggings: Fabletics High-Waisted PowerHold Leggings
Fabletics isn't kidding when it calls these High-Waisted PowerHold Leggings (£69). They tick all of the requisite boxes; the high-waist cut helps you feel supported while you exercise, and the superthick material definitely remains opaque as you squat. You can also nab these tights cheaper if you sign up for one of Fabletics' monthly subscriptions.
