You might think of thermals as winter’s wingwoman, essential when the mercury drops, but forgotten once the sun sticks around. Here's the thing: not all thermals are created equal.

At The Foundation, we’re flipping the script. Women's Thermals are no longer just a cold-weather staple, they’re now your go-to for summer layering, too. And yes, we mean it.

Wait... Thermals in Summer?

Before you write us off, hear us out. Not all thermals are thick, scratchy, or designed to trap heat like you're camping in the Alps. At The Foundation, we focus on lightweight, breathable options made from skin-loving fabrics that work with your body, not against it.

That means soft Australian cotton, gentle stretchable fibres, and designs that sit like a second skin under your clothes. Think: no bulk, no sweat, just comfort. Especially when you're dealing with icy aircon or those unpredictable early-morning chills.

The Secret to Summer Layering

So, why layer in the first place?

• Office AC that could rival the Arctic
• Early morning walks before the sun kicks in
• Weekend brunches that turn breezy
• Travel days (hello, airplane chill!)

Lightweight thermal tops, thermal vests, and our favourite TBL Modal Camisole are ideal under a shirt, dress or even solo with a comfy pair of linen trousers. They add just enough coverage without making you feel like you’re wrapped in cling wrap.

Why Cotton Thermals Win Every Time

We don’t believe in suffering for style. That’s why we’re obsessed with breathable base layers that give you:

• Natural temperature regulation (no overheating here)
• Skin-kind softness
• Side seamfree comfort
• Stretch that moves with you

Forget synthetic, stuffy layers. Our curated selection of thermal clothing is all about everyday ease and yes, it still fits like a dream.

Hot tip: Our 100% cotton thermal tank is launching soon. Keep your eyes peeled, it’s the piece your summer layering dreams are made of.

Swap the Bulk for Breathable

If your current winter wardrobe is all puffer jackets and heavy knits, it might be time to rethink your approach to cooler weather layering. Instead of overdoing it, opt for smarter materials and well-designed pieces.

From long sleeve styles to thermal bottoms like our TBL Modal Cashmere Legging, we've made it easy to build your base from the skin out. The result? A wardrobe that works harder and feels better.

Built for Australian Summers (And Aircon Battles)

Designed for outdoor use, travel, errands, lounging. Our summer-friendly women's thermals work whether you're running between meetings or running after the kids. And they do it without bunching, overheating, or adding bulk.

This is comfort that works with you, not against you.
