I have struggled to find front wedgie proof underwear that actually works for the gym for so long and these have exceeded all my expectations! They are lightweight, comfortable and you don’t even feel the padding. You also don’t have to adjust while working out, I’ll definitely be purchasing more!

Wondera are one of those products that you want to be in your life foreverrrr!! I can finally wear a bunch of lululemon pants that I couldn’t before. When I go shopping I no longer have to think about whether pants/leggings will give me a camel toe. You girls are incredible!! Please never stop making these!
