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.
