Biopod DownWool Subzero 175

The Biopod DownWool Subzero 175 is a high-quality three-season sleeping bag that is ideal for trekking, biking, backpacking and camping. Weighing 900 g and packing down to 18 x 20 cm, the Biopod DownWool Subzero 175 will keep you warm and cosy even in temperatures down to -4°C.

Grüezi Bag’s own innovative DownWool filling combines the insulating powers of down with the temperature and moisture regulating properties of wool to provide a comfortable and dry sleeping environment.

Features:

• Head pillow pocket: By inserting, for example, a fleece jacket into the pillow pocket, the sleeping bag provides a non-slip pillow.
• Adjustable hood with Face Baffle: The heat collar conforms perfectly to the shape of the head. When it’s cold, only a small face opening remains, which minimizes heat loss around the face.
• 3D Heat Collar: Automatically seals in the zipper area, preventing cold spots.
• Drawstring Pocket: To prevent the drawstring from the heat collar getting in the way.
• Internal & external pockets: For valuables and items you want to keep close.
• Two-way auto-lock zipper: The zipper can be opened and closed from either end and from inside and outside. The auto-lock feature prevents accidental opening.
• White zipper: Helps to locate the zipper in the dark.
• Zipper with anti-snag design and reinforced robust strap: Makes the zipper easier to use and helps prevent catching the fabric.
• Reinforced zipper cover: Prevents heat loss and avoids cold spots.
• Foot ventilation system: The innovative zipper layout allows feet to be comfortably placed on the top of the sleeping bag, allowing excess heat to escape whilst staying warm and cosy.
• Pre-formed footbox: With multiple chambers to avoid cold spots and provide ample space for your toes.
• Feater loops: A warming hip sack with heating element (Feater - The Feet Heater) can be added.
• Chamber construction: H-Chambers, V-Shaped (on the top), shaped foot area with multiple chambers.
• Includes: Sleeping bag, compression sack & storage bag.

Care Instructions

Washing

• The washing instructions are located in the inner pocket of the sleeping bag.
• The sleeping bag can be hand-washed with a down-specific detergent at a maximum of 30°C/86°F or machine-washed using the wool wash cycle. Please turn it inside out, zip it up, perform an additional rinse cycle, and do not use fabric softener.
• Remove the item from the machine, fluff it up a bit, and run an additional spin cycle at a maximum of 600 revolutions.

Drying

• Dry in a tumble dryer at a maximum of 60°C/140°F, and be sure to add 2-3 tennis balls for better fluffing.
• Please perform multiple drying cycles, and after each cycle, remove the item from the machine, shake or fluff it well, and allow it to cool down in between.
• The dryer should be set on a timed program to ensure thorough drying of the down.
• If a tumble dryer is not available, the sleeping bag can be placed on a laundry rack on sunny days and should be frequently shaken to allow air from above and below to circulate.

How do you know when the drying process is complete?

• If the item still doesn't have its original thickness, you need to repeat the drying cycles until the sleeping bag feels more filled than before.
• Depending on the water resistance of the outer material, the drying process may take varying lengths of time (at least 2 days, depending on the dryer model).
• The down must be completely dry. If the sleeping bag is not properly dried and fluffed, there is a risk of clumping the down feathers. This could irreparably damage the sleeping bag. Damp down may have an odour, but this odour will dissipate when the sleeping bag is fully dry.

Tip

• Down sleeping bags should be periodically dried with tennis balls in the tumble dryer to remove excess moisture.
• Sleeping bags should be stored open and dry in their storage bag. An old pillowcase can also serve as a suitable storage bag.
• When packing in the compression sack, the sleeping bag should be stuffed with the foot end first, not rolled or folded.
• Airing out a sleeping bag is preferable to washing. Hybrid sleeping bags require less frequent washing because wool naturally possesses odour-resistant and dirt-repellent properties. We recommend cleaning small external stains gently (as described above), and heavily soiled or greasy sleeping bags can be washed in a washing machine.
