Understanding Flat Seam vs. Soft Seam

What is Flat Seam vs Soft Seam?

Soft Seam WunderUndies are our original design. They do have exposed seams but they are incredibly soft due to our fabric blend of bamboo and cotton. They are the solution to sensory problems for many kids.

Our Flat Seam Undies are our newest design. All of the seams are external and sewn completely flat for the most comfort possible. These are the solution for the most sensitive kids.

Underwear Designed for Sensitive Kids

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.
