Grüezi Bag DownWool Ice 2.0 – warm sleeping bag for winter and cold conditions

Description

Warm sleeping comfort for cold nights

Grüezi Bag DownWool Ice 2.0 is designed for trips where temperatures fall well below freezing and you need significantly more warmth than a conventional three-season sleeping bag can provide. With a comfort temperature of −6 °C, it is designed for cold nights from autumn through spring, while DownWool® insulation helps maintain a comfortable sleeping climate as temperature and humidity change.

Ice 2.0 is an excellent choice for winter hiking, trekking, camping and other cold-weather adventures when you need high insulation performance without moving up to the weight and bulk of an expedition sleeping bag.

Down + wool – why DownWool®?

DownWool® 2.0 combines 70% down with 30% wool. The down provides excellent insulation with relatively little weight and pack volume, while the wool helps regulate both temperature and moisture inside the sleeping bag.

This becomes particularly valuable in cold conditions. Your body releases moisture throughout the night, and increasing humidity can reduce the insulating performance of conventional down. The wool in DownWool® helps create a more balanced microclimate and makes the insulation less sensitive to humid conditions.

In practical terms, this means a more stable and comfortable sleeping climate throughout the night – even as temperature and humidity change.

For winter and cold conditions

DownWool Ice 2.0 is tested according to EN ISO 23537-1 with a comfort temperature of −6 °C, a limit temperature of −12 °C and an extreme temperature of −33 °C. Grüezi Bag recommends an operating range of −6 to +15 °C.

The comfort temperature is the most useful reference point when choosing a sleeping bag for normal use. The limit temperature represents a lower temperature at which a standard adult male can still be expected to remain warm in a curled sleeping position. The extreme temperature is a survival-related safety rating and should not be used as a target temperature for normal sleeping conditions.

Individual sensitivity to cold varies considerably. If you tend to feel the cold, or are travelling in conditions where temperatures can fall rapidly, always allow an additional temperature margin. Your sleeping mat, clothing, wind, humidity, food intake and fatigue can also affect how warm you feel during the night.

Designed to reduce heat loss

Ice 2.0 features a 3D thermal collar that helps retain warm air inside the sleeping bag and reduce heat loss around the neck and zip area. The collar also closes around the zip area to help minimise cold spots.

The adjustable hood with Face Baffle can be drawn closely around the head as temperatures fall, leaving only a small opening around the face. A dedicated pocket keeps the thermal collar drawstrings neatly out of the way during the night.

An insulated zip baffle running alongside the two-way zip further reduces heat loss and helps minimise cold spots along the side of the sleeping bag.

Comfort and ventilation across changing temperatures

Even a warm sleeping bag needs effective ventilation. Grüezi Bag’s foot ventilation system allows excess heat to escape – or your feet to rest outside the bag – without having to open the entire sleeping bag.

The pre-shaped footbox provides plenty of room for your feet and toes, while the multi-chamber construction around the foot area helps maintain even insulation in one of the areas most susceptible to feeling cold.

Ice 2.0 also features internal and external pockets for small essentials, a two-way auto-lock zip with anti-snag protection and a practical pillow pocket that can be filled with a fleece jacket or other soft clothing to create a secure pillow.

Comfortable fit

Ice 2.0 has a comfortable mummy shape that provides more freedom of movement than very close-fitting, minimalist sleeping bags. This allows for a more natural sleeping position and makes it particularly comfortable for side sleepers and anyone who tends to move around during the night.

At the same time, the mummy shape retains the thermal efficiency that becomes particularly important as temperatures fall below freezing.

Choose the right length

DownWool Ice 2.0 is available in Regular, Long and Extra Long, allowing you to choose a sleeping bag that matches your height rather than relying on a single universal length.

Regular is designed for body heights up to 175 cm, Long up to 185 cm and Extra Long up to 200 cm. If you are close to the upper end of a size range and prefer additional room, you may also want to consider the next size up.

Choosing the right size is particularly important in a sleeping bag designed for cold conditions. An unnecessarily large sleeping bag contains more air for your body to warm, while a bag that is too short can compress the insulation around the foot or head area and reduce its thermal performance.

Recycled materials and DownWool® 2.0

The outer and inner fabrics are made from 100% recycled 20D 380T nylon. The material is lightweight and breathable while also being wind- and water-resistant.

DownWool® 2.0 insulation consists of 70% duck down and 30% mechanically processed wool. The 90/10 down has a fill power of 700+ cuin. Regular contains approximately 652 g of DownWool®, Long approximately 789 g and Extra Long approximately 950 g.

Ice 2.0 is made in Germany and supplied with a compression stuff sack and storage bag.
