DEUTER Astro Pro 600 -12°C/10°F Magma-Titanium perový spacák s ľavým zipsom

The DEUTER Astro Pro 600 redefines cold-weather comfort with its premium 90/10 duck down fill and Thermo Stretch Comfort construction, delivering exceptional warmth-to-weight performance for alpine expeditions and winter camping. Unlike conventional mummy bags that restrict movement, this model integrates elasticated zones that expand with your body, allowing natural side-sleeping positions without compromising thermal efficiency. The trapezoid chamber design eliminates cold spots by ensuring even down distribution, while the RDS-certified insulation guarantees ethical sourcing. Rated for three to four seasons, it excels in temperatures down to -12°C, making it a reliable companion for high-altitude bivouacs and frosty shoulder-season adventures.

Highlights

• 650+ cuin fill power with 600 g of 90/10 duck down for superior loft and packability
• Thermo Stretch Comfort system provides flexible fit and freedom of movement
• Left-side zipper with anti-snag guard and full-length draft tube
• RDS-certified down ensures responsible animal welfare practices
• Lightweight 20D PA ripstop shell with soft-touch lining for next-to-skin comfort

In daily use

From the moment you slip inside, the Astro Pro 600 feels like a tailored cocoon. The soft 20D polyamide lining wicks moisture while the trapezoid baffles keep down from shifting, maintaining consistent warmth throughout the night. The left zipper allows easy entry and can be paired with a right-zip model for a double bag. At 185 cm max user height, it accommodates most campers, and the 75 cm shoulder width provides ample room for layering. When morning comes, the included compression sack reduces the bag to a mere 9.7 liters, freeing pack space for other essentials. Whether you're a side sleeper or toss-and-turner, the stretch panels adapt silently, eliminating the claustrophobic feel of traditional mummy bags.
