The Patizon G 600 is a mummy-shaped down bag filled with 600 g of premium European goose down (850 cuin, 90/10 ratio). EN ISO 23537 testing gives a comfort rating of -6 °C and a limit of -12 °C, with an extreme of -32 °C — figures that sit between three-season and winter use rather than pure summer touring.
An ultralight Toray Airtastic shell (33 g/m²) with a DWR finish keeps weight down, while horizontally oriented box baffles stop the down from shifting. The 30×21 cm packed size is reasonably compact given the warmth on offer.
At 930 g in size M, the G 600 suits autumn and spring mountain trips and lighter alpine outings where you want a margin against frost without carrying a full winter bag. It's made in the Czech Republic.
