When the temperatures rise, keeping your kids comfortable — especially those with eczema, sensitive skin, or sensory sensitivities — can feel like a full-time job. Sweat, synthetic fabrics, and scratchy seams often trigger irritation, meltdowns, and skin flare-ups. Fortunately, the right underwear can make a world of difference.
We explore the best underwear for kids in hot weather and show you what to look for to keep your family feeling fresh, dry, and irritation-free all summer long.
Just Peachy’s Bestselling Style: Wedgie-Free Panties are now available in new colors and teen sizes
Why Summer Makes Sensitive Skin Worse
Kids’ skin is thinner and more delicate than adults’ — which means it’s more easily irritated by:
-
Heat and humidity: Leads to sweat rashes and itchiness.
-
Synthetic fibres: Trap heat and moisture, increasing the risk of chafing and irritation.
-
Tight elastics and itchy tags: Common sensory triggers for kids with tactile sensitivities.
That’s why choosing the right underwear — especially for kids with eczema or sensory sensitivities — is so important.
Hot weather can exacerbate eczema and sensory sensitivities. Just Peachy Underwear helps to create a breathable and moisture-wicking barrier that helps soothe sensitive skin instead of aggravating it.
What to Look for in Kids’ Underwear for Hot Weather
When choosing underwear for kids in the summer months, look for:
-
Ultra-soft, breathable fabrics like TENCEL™ Micro Modal — this is naturally moisture-wicking and 50% more absorbent than cotton.
-
Seamless or tag-free designs to minimise friction against the skin.
-
Gentle elastics that won’t dig in to prevent welts and wedgies.
-
Full-coverage, wedgie-proof cuts for all-day comfort.

Bonus Tips to Keep Kids Cool & Comfortable:
