For just $12, with coupon code 2FOR12, you get 2 consecutively sized pairs of underwear to help you and your kid not just determine how much they like WunderUndies, but what size fits best.

Once you've got that figured out, you can come back for all the fun designs in their perfect size!

Underwear Designed for Sensitive Skin

WunderUndies kids’ sensory-friendly underwear is made for children who struggle with uncomfortable clothing, scratchy seams, or tight elastic waistbands. Our bamboo underwear is soft, breathable, latex-free, and designed with external flat seams to help reduce irritation against sensitive skin. Many families choose WunderUndies for kids with sensory sensitivities, autism, SPD, eczema-prone skin, or general clothing sensitivity. If your child has trouble tolerating traditional underwear, this collection is designed to offer a softer, gentler everyday option.
