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.
