What is the warmest item of clothing?

A natural down expedition jacket. The BALTORO (men’s) and KHUMBU (women’s) are filled with 800 cuin down and designed for belays and high-altitude bivouacs. In wet conditions, the HIMALAYAN’s synthetic insulation retains warmth even when wet, according to its product details.

What should you wear to stay warm?

Three layers: a thermal base layer next to your skin, a fleece or down jacket, then a windproof jacket. Cover your head and hands, and fasten the cuffs and hem of your jacket to keep cold air out.

Which coats are warmest for winter?

For everyday winter wear and travel, the MEIJE (men’s) and MORZINE (women’s) hooded down jackets work in town and on hikes, and pack into their compression sacks. For expeditions, choose the BALTORO and KHUMBU down jackets. You’ll find every model in our warm jackets.

What are clothes designed for cold weather called?

They’re called thermal or insulated clothing. A thermal base layer goes next to the skin, a fleece forms the mid-layer, and a down jacket provides the warm layer. Wear a windproof or waterproof jacket over the top when it’s windy or snowing.

How to dress for extreme cold: the three layers

After ten minutes waiting for a shuttle or the Northern Lights, you feel the cold at your wrists and lower back. In extreme cold, wear three layers. Against your skin, a thermal base layer. Over that, a fleece or insulated jacket to retain heat, then a windproof jacket or waterproof jacket. When you stop, add warmth to your mid-layer; while moving, open it up before you start to sweat. Then close off draughts using the drawcord at the jacket hem and the thumb loops at the cuffs. For a trip to the Far North, read our guide to kit up for a trip to Lapland.

Jacket or coat for extreme cold: natural down or synthetic insulation?

In dry cold, choose a natural-down jacket. The BALTORO (men’s, 610 g) and KHUMBU (women’s, 510 g) are expedition down jackets with 800 cuin fill. The more compact MERU (480 g) and LORY (400 g) each contain 150 g of the same down.

If the snow is wet or you’re sweating, choose synthetic insulation : according to their product specifications, Cimaloft insulated jackets retain warmth even when wet. The HIMALAYAN (1,250 g) is made for bivvies and exposed stops. The MEIJE (men’s, 515 g) and MORZINE (women’s, 449 g) have hoods and pack into their compression sacks.

Compare these details on each product page:

Insulation: 800 cuin natural down or synthetic Cimaloft.
Weight: from 400 g for the LORY to 1,250 g for the HIMALAYAN.
Wind protection: 60 to 90 km/h for down jackets, 40 to 60 km/h for Cimaloft jackets.
Sizing: the BALTORO, KHUMBU and HIMALAYAN run large, so choose a size down.

Find every model in our men’s down jackets and our women’s insulated jackets.

Fleece for extreme cold: full-zip jacket, half-zip top or gilet

A fleece sits between your base layer and jacket. The ARTIC (300 g) opens fully for ventilation; the ADELIE (285 g) has a half-zip and a high collar. Both use THERMOPOLAR 200, made from 100% recycled polyester. To warm your torso without adding bulk to your arms, choose the ICEBERG gilet : 395 g of long-fibre THERMOPOLAR 300, worn under a jacket. For women, the JORASSE (445 g) has a built-in cold-weather face covering and thumb loops, while the ORBA (500 g) is a hooded windproof fleece. Explore the full range in our fleeces.

Thermal base layers and cold-weather trousers

Against your skin, WOOL 240 is our thickest merino: 240 g/m² of wool for long stops and bivvies. For a synthetic option, X-WARM combines two insulating fabrics; the lighter WARM is suited to active use. WOOL 240 and WARM are also available as long johns.

For your legs, choose the QUEBEC trousers : a softshell with a 10,000 mm membrane that blocks winds of 60 to 90 km/h and works both on the trail and in town. The shorter men’s version takes 6 cm off the leg length. For extreme cold, its product page recommends thermal leggings underneath. On your feet, MERINO SOCKS contain 63% merino wool. Explore our thermal base layers and our warm trousers.

Outer layer and extremities: complete your cold-weather kit

A down jacket’s water-repellent treatment will only keep out a light shower. In snow or rain, switch to a waterproof jacket over the top : the COSMIQUES (390 g) has a 20,000 mm Ultrashell membrane and sealed seams.

On frozen ground, Lowa RENEGADE EVO ICE GTX boots grip the ice. Go up half a size to make room for thick socks. Complete your kit with our gloves and mittens and our beanies and headbands. All Cimalp clothing comes with the lifetime repairs.
