Frequently Asked Questions
Need more info? We’ve got you covered.
Which kids underwear style should I choose?
The best underwear style depends on your child’s comfort and daily activities. Briefs offer a snug fit and full support, making them great for active kids. Boxer briefs provide more coverage and help prevent chafing, especially under uniforms or during sports. Hipsters or bikinis offer a mid-rise, flexible fit that many kids prefer for everyday wear. If your child has sensitive skin, opt for our Natural (no dye) underwear.
Do you have potty training underwear?
All of our underwear has a double layer of fabric for small accidents but no additional absorbent material. The absorbent layers in some potty training underwear usually use materials that can have harmful chemicals. This is why we suggest the use of cotton underwear like ours even when potty training.
Are your products suitable for children or adults with eczema or other skin conditions?
While no brand can guarantee that any product will work for every child with eczema, many of our customers with sensitive skin have had positive experiences with our underwear.
Our founder, Melita, was inspired to create better basics after struggling to find options that didn’t irritate her son’s eczema. That’s why our underwear is made with high organic cotton content. Designed to be soft, breathable, and gentle on delicate skin. Breathability is especially important, as trapped moisture and heat can often trigger irritation.
We focus on minimizing common irritants by using non-toxic dyes, avoiding harsh chemicals, and designing with comfort in mind for all-day wear. While every child’s skin is different, we’ve seen a high success rate among families looking for eczema-friendly essentials.

How should I wash organic cotton underwear?
Wash in cold or warm water with gentle detergent and avoid bleach or fabric softeners to maintain softness.
Why choose organic underwear over regular cotton?
Unlike conventional cotton, organic cotton avoids toxic dyes and pesticides, reducing skin irritation and supporting healthier, more sustainable farming practices. To learn more about our certifications click here.
Where is your underwear made?
Our underwear is made in a family owned, GOTS certified facility in India.
Does organic cotton underwear help prevent rashes?
Yes, its breathable, chemical-free fabric helps reduce moisture buildup and irritation, which can lead to rashes.
What’s the difference between 95% organic cotton and 100% organic cotton underwear?
The main difference comes down to stretch and structure. 100% organic cotton underwear is made entirely from natural fibers, offering maximum breathability and a soft, natural feel; ideal for sensitive skin. However, it has less stretch.
95% organic cotton underwear includes a small amount of elastane, which adds stretch, flexibility, and helps the underwear maintain its fit after washing. This blend is often preferred for kids because it moves with their bodies and stays in place throughout the day.
Both options are safe and comfortable.
