When you’re out hiking in winter, it’s not just about keeping warm – it’s about staying comfortable, dry, and flexible as the conditions change. That’s where layering comes in. The right combination of leggings, trousers, fleeces, gilets, and jackets will help regulate your body temperature and protect you from the elements.
ACAI Outdoorwear has built a reputation for designing performance clothing made specifically for women. Their focus on function, fit, and fashion makes layering simple – and stylish.
Here’s how ACAI’s leggings, trousers, outerwear, and accessories come together to create the ultimate layering system for women hikers this winter.
Why Layering Matters
Layering allows you to adapt to shifting weather and activity levels. Each layer serves a purpose:
- Base Layer – Keeps moisture away from your skin.
- Mid Layer – Adds insulation and warmth.
- Outer Layer – Protects from wind, rain, and snow.
- Accessories – Keep extremities warm and prevent heat loss.
By mixing ACAI’s products, you can create a system that feels as good as it looks.
Base Layer: Leggings
Your base layer should be soft, warm, and moisture-wicking. ACAI’s thermal leggings are designed with exactly that in mind.
Thermal Altitude Leggings
Perfect for cold-weather hikes. Their brushed lining keeps you cosy while the four-way stretch gives you total freedom of movement.

Fleece Mid Layers
ACAI’s fleeces offer soft warmth that’s easy to layer under jackets. Look for lightweight fleece pullovers or full zips that can be removed quickly if you warm up mid-walk.
Gilets
The unsung hero of winter layering, a gilet adds warmth to your core while keeping your arms free for movement. ACAI’s gilets are lightweight, packable, and perfect for pairing with leggings or thermal trousers.

Outer Layer: Jackets & Overtrousers
When the wind picks up or rain starts to fall, your outer layer keeps you dry and protected.
Cloudguard Jacket
ACAI’s Cloudguard Jacket is water-resistant, windproof, and surprisingly lightweight. With a flattering cut and soft-touch fabric, it’s both technical and stylish — ideal for unpredictable UK weather.

Overtrousers
Waterproof and breathable, these slip easily over your base or mid layers. They’re a must-have for serious hikers who refuse to let the rain stop play.
Accessories: Snoods & Beanies
Even the best layering system can fail if you lose heat through your head or neck. ACAI’s winter accessories finish the outfit perfectly.
Snoods
Soft, warm, and versatile — wear them around your neck, over your face, or under your jacket collar to trap heat.
Beanies
A classic winter essential. ACAI’s beanies are cosy yet breathable, helping retain heat without overheating when you’re on the move.
