FEEL THE DIFFERENCE
The Grüezi bag® brand focuses on the best sleeping comfort and functionality: the climate and cut have already received several awards.
The special thing about this sleeping bag is its innovative insulation: you quickly feel that you are not getting too cold or too warm in a DownWool® sleeping bag. It creates a dry body climate and compensates for temperature fluctuations.
This is achieved through the innovative mix of natural materials down and wool. This combination is patent pending and acts as a light and natural air conditioning system. The DownWool® sleeping bag from Grüezi bag® offers significant advantages over pure down or synthetic fiber sleeping bags:
Nothing insulates as well as high-quality down, because down has a very high insulation performance with a low weight.
However, down only insulates as long as it is dry and fluffy. As humidity increases, the fine branches of the down collapse, the down clumps and the insulation ability decreases significantly. Chemical agents are often used to make the down water-repellent. With DownWool®, the treatment of the down becomes unnecessary thanks to the addition of wool: wool naturally keeps the down drier and thus maintains the insulating effect of the down.
Wool can absorb up to 30% of its own weight in moisture via its capillaries and release it back to the outside in a measured amount - so that no evaporation cold occurs. This not only ensures effective moisture regulation, but also body temperature regulation. Even when wet, it retains its warming properties, something no other material can do. Wool naturally creates a cosy and pleasant microclimate thanks to its unique climate-balancing properties. The wool also neutralises unpleasant sweat odours.
Thanks to the unique effectiveness of DownWool® insulation, your body can save itself some of the energy-consuming work of regulating body temperature. The energy saved is available for regeneration while you sleep.
The result is good insulation and a wide temperature range in which you feel comfortable and can sleep well. This makes DownWool® sleeping bags from Grüezi bag® popular all-rounders.

Features
Cut:
A sophisticated cut ensures optimal freedom of movement: the comfort cut allows you to sleep more peacefully even in the mummy shape, as you can turn into a side position with your leg bent as well as inside the sleeping bag.
Features:
Pillow compartment : If you put a fleece jacket, for example, into the pillow compartment, the sleeping bag has a non-slip pillow.
Adjustable hood with face baffle : The heat bead adapts perfectly to the shape of your head. When it's cold, only a small face hole remains open and therefore there is less loss of temperature in the face.
Inside & outside pocket : For valuables and things you prefer to keep close to you.
Two-way autolock zipper : The zipper can be opened and closed from either end and from the inside and outside. Auto-lock prevents it from opening accidentally.
White zipper : This makes it easier to find the zipper in the dark.
Zipper with anti-snag zipper and robust webbing underneath : This makes the zipper even easier to operate without pinching the outer fabric.
Zipper with an underlaid zipper cover : so that heat cannot escape and cold spots are created.
Foot ventilation system : Thanks to the innovative zipper system, the feet can be placed comfortably on the top of the sleeping bag and excess heat can escape.
Pre-shaped foot box: when lying down there is enough space in the sleeping bag to put your toes up.
Feater loops : Heat hip bag with heating element (Feater - The Feet Heater) can also be installed.
Chamber construction : H-chambers, V-shaped (on the top), pre-shaped foot area with multiple chambers
Included in delivery : sleeping bag, compression stuff sack, storage bag.

Size + Specifications
Temperature range according to EN 23537: T Comfort: 8 °C (46 °F) | T Limit: 3°C (37°F) | T Extreme: -11°C (12°F). This means that the sleeping bag has a large comfort range of 8 °C to 24 °C.
Size : Mummy sleeping bag with 215 x 80 x 50 cm (suitable for a body height of 176 cm to 190 cm with a normal stature. For people with a wider stature, we recommend the larger sleeping bag version from 185 cm tall.)
Weight : approx. 850 g + pack bag
Pack size : Ø 17 x 31 cm, compressed Ø 17 x 19 cm
Packing volume : 7 litres, compressed 4.5 litres
Outer and inner fabric: Ultralight, durable and recycled 20 denier 380T nylon (100% polyamide) that feels incredibly soft, supple and silky on the skin. This is achieved by pulling the fabric over hot rollers to constrict the pores. This makes the fabric down-proof, impermeable to clothes moths and still remains naturally breathable without the usual plastic coating. The pores do not stick together either due to the bio-based BeSoDRY-ECO impregnation or the sustainable BEMACRON dyes. The outer material is therefore windproof and highly water-repellent.
Filling : 369 g DownWool® made from 70% high-quality down (90/10 with fill power at least 650 cuin) and 30% mechanically refined wool
Material identification : Shell 100% polyamide, filling 70% down/30% wool - contains non-textile parts of animal origin.
Area of application : the ideal companion for summer trekking and bike tours as well as camping and caravans -
