Why Natural Fibres Matter More in the Summer Than You Think
You’ve finally made it outside. The sun is shining. Your little one is barefoot in the grass, chasing bubbles, cheeks pink from excitement - and then, all of a sudden, they’re tugging at their shirt or asking to go inside. They’re too hot. Uncomfortable. It’s not the sun that’s the problem - it’s the fabric.
What your child wears in summer matters far more than we realise. And not just for how they look, but for how they feel. Especially when the temperatures rise, the wrong fabric can quickly lead to irritability, overheating, and unhappy skin.
At Mika & Milo, we believe that the fabric closest to your child’s skin should comfort them, never irritate them. That’s why we use natural fibres - specifically, a blend of GOTS-certified organic cotton and a whisper of Mongolian cashmere - to create breathable summer layers that are made for movement, softness, and long sunny days.
Synthetics in Summer: Why They Just Don’t Work
Synthetics like polyester, nylon, and acrylic trap heat against the body. They don’t allow moisture to escape, meaning sweat builds up - creating the perfect storm for sticky skin, irritation, and even heat rash.
And for children with eczema, allergies, or sensitive skin? These fibres can make a hot day feel unbearable.
Compare that to natural fibres - which allow air to move, moisture to evaporate, and skin to breathe. The difference isn’t just visible. It’s felt.
What Makes Organic Cotton So Special?
Our GOTS-certified organic cotton is:
- Grown without synthetic pesticides
- Free from toxic dyes or finishes
- Softer and stronger than conventional cotton
- Naturally hypoallergenic and biodegradable
Take, for example, our Baby Lion Jumper. It’s light enough for daytime breezes and soft enough for sunset cuddles - a gentle knit that doesn’t just wrap your child in warmth, but in intention.
Cashmere in the Heat? Yes - When It’s Done Right
Our summer knits are made with 95% organic cotton and 5% Mongolian cashmere - just enough to elevate the feel without adding weight or heat. The result? A garment that’s:

- Exceptionally soft
- Naturally temperature regulating
- Keeps its shape wash after wash
Our Baby Lightning Bolt Onesie is a perfect example. It's bright, breathable, and built for movement - with a softness that invites hugs and holds up beautifully through wear and wash.
Why Natural Fibres Matter Even More for Babies
Babies regulate their body temperature differently than adults. Their skin is thinner, more absorbent, and more prone to discomfort - especially in warm weather.
That’s why we create garments like our Baby Pants with Knee Pads - breathable softness with just enough structure for crawling, tumbling, and toddling. They’re as practical as they are gentle.
The Invisible Comfort You Can Feel
Children may not be able to explain why they feel calmer, lighter, or more at ease in natural clothing - but they feel it. And as parents, we see it in their movements, their moods, their skin.
Natural fibres don’t just make sense on paper. They change how summer feels - creating space for joy instead of discomfort.
