Midlayers to Layer Up

Q&A

Answer:

Think of it like choosing your playlist—it all depends on the vibe (and the temperature).

Lightweight – For fast-paced days or milder winter weather (we call this ACTIVE)

Midweight – The all-rounder for variable conditions (we call this PRO)

Heavyweight – For deep-freeze days and low-intensity adventures (we call this EXTREME)

Kombi’s got all three, so you can layer smart based on your pace, your plans, and the ever-changing forecast.

Answer:

Every KOMBI base layer—whether RedHEAT™, MerinoMIX, or Polartec®—is designed to move, breathe, and perform with total comfort in mind.
Our fabrics are soft, stretch-friendly, and naturally kind to your skin, with built-in technologies that manage moisture, regulate temperature, and keep odours in check.

Because we believe high performance should always feel good—from first layer to last run.

Answer:

It all comes down to feel and performance.

Merino wool blends like our MerinoMIX combine natural warmth and breathability with the softness and stretch of synthetic fibres — perfect for all-day comfort and temperature balance.

100% synthetic fabrics like RedHEAT™ and Polartec® focus on pure performance: they dry faster, breathe better, and stay fresh longer, even through intense activity.

Both keep you warm and comfortable — it’s just about how you like to move and feel.

Answer:

MerinoMIX is where nature meets next-gen comfort. We blended mulesed-free Merino wool with our favourite 4-way stretch synthetic fibres to give you the best of both worlds.

Here’s what you get:

- Warmth and temp regulation from Merino
- Plus synthetic perks: ultra breathability, odour control, and a silky-soft feel that moves with you

It comes in two tailored options:
- MerinoMIX ACTIVE (145g/m²) – Lightweight for high-energy days
- MerinoMIX PRO (180g/m²) – Midweight for versatile layering

Because when it comes to comfort, we believe in more tech, less compromise.

Answer:

RedHEAT™ is our most advanced base layer, built to balance your body temperature with visible carbon microcrystals that store and release heat as you move.

Why it stands out:
- Keeps you perfectly warm — never too hot or too cold
- Breathable, quick-drying, and soft like a second skin
- Naturally odour-resistant for lasting freshness

Available in three warmth levels:
- ACTIVE (150 g/m²) – Lightweight for high-energy days
- PRO (200 g/m²) – Midweight for everyday adventures
- EXTREME (265 g/m²) – Heavyweight for deep-freeze conditions

From dog walks to downhill runs, RedHEAT™ keeps up — and keeps you comfortable.

Answer:

Polartec® is the newest addition to the KOMBI family — and it’s changing the game for performance layering.

Built with recycled, high-performance fabrics, Polartec® base layers deliver breathable comfort, moisture control, and quick-drying performance.

It's available in two techs, two weights:
- Power Dry (120 g/m²) – Lightweight and ultra-breathable for high-intensity days.
- Power Grid (170 g/m²) – Midweight warmth with grid-style insulation for cooler temps.

Answer:

Go lightweight — you’ll thank yourself halfway up the hill.

When the pace picks up, you need layers that breathe and dry fast.
RedHEAT™ ACTIVE (150 g/m²), MerinoMIX ACTIVE (145 g/m²), and Polartec® Power Dry (120 g/m²) are built for movement. They’re lightweight, ultra-breathable, and quick to wick away sweat — keeping you warm without overheating.

Lightweight base layers are your best pick for skiing, touring, running, or any high-output winter adventure where performance and comfort need to move in sync.

Answer:

Go heavyweight — that’s your cozy cure.

When the chill hits hard, nothing beats a heavyweight base layer.
RedHEAT™ EXTREME (265 g/m²) is our warmest, softest option, built to trap body heat and keep you comfortable even in deep-freeze temps.

If you still want flexibility for layering, try RedHEAT™ PRO (200 g/m²) for slightly lighter warmth with all-day comfort.

Heavyweight layers are your best defence against the cold — insulating, breathable, and designed to feel like a warm hug from the inside out.

Answer:

Every KOMBI base layer is made with care — for you, and for the planet.

RedHEAT™ and Polartec® use durable synthetic fibres designed to last season after season.
MerinoMIX blends mulesed-free Merino wool with responsibly sourced synthetics for comfort that endures.
Polartec® fabrics are crafted from recycled plastic bottles, giving new life to existing materials.

No matter which fabric you choose, every KOMBI layer is built for long-lasting warmth, comfort, and performance — made responsibly from the first stitch to the last.

Answer:

We sure do—but we like to blend the best of both worlds.

Enter MerinoMIX, our custom combo of mulesed-free Merino wool and 4-way stretch synthetic fibres. Why? Because while Merino brings natural warmth, breathability, and temperature regulation, the synthetic side cranks up the durability, softness, odour resistance, and moisture management.

The result: a next-level base layer that’s part nature, part innovation, all comfort. Available in:
- MerinoMIX ACTIVE (145g/m²) – Lightweight, perfect for active days
- MerinoMIX PRO (180g/m²) – Midweight, your cold-weather layering go-to

Because natural doesn’t have to mean old-school.

Answer:

No worries—we’ve got you covered.

RedHEAT and Polartec® base layers are made from 100% synthetic fibres, so they’re hypoallergenic, ultra-soft, and naturally antimicrobial—perfect for sensitive skin or wool allergies.

If you’re curious about Merino, our MerinoMIX collection blends mulesed-free Merino wool with stretchy synthetic fibres to reduce irritation while boosting breathability and odour control.

In short: comfort, performance, and peace of mind—whichever way you layer.

Answer:

Absolutely. All our fabrics are hypoallergenic, breathable, and ultra-soft, so you can layer up without irritation.
If you’re wool-sensitive, RedHEAT™ and Polartec® offer 100% synthetic comfort that’s smooth and gentle.
If you prefer a natural touch, MerinoMIX balances Merino warmth with silky stretch fibres for the perfect middle ground.
