Patagonia 850 Down Sleeping Bag 30°F / -1°C

Now, I introduce to you the lighter, more minimalist little brother of the 19 F. sleeping bag.

This offering clocks in at only 24 oz. and compresses to the size of a loaf of bread. Like its bigger brother it has a front, over the top zipper, but of only half-length. Despite this shorter zip length the bag still has similar benefits to its sibling as the zipper is two-way, allowing one to stay fully zipped in but still have use of their hands through an unzipped hole at chest height. Again, this also has benefits on a bivy ledge where the snoozing climber can be tied in through a small
opening at the bottom of the zipper, as opposed to down the neck of the bag.

This bag in not fully baffled, but is made with sewn-thru construction. This design stitches the inner nylon from the bag to the outside shell, trapping the down in place; however, at these points where the nylon shells are zippered together there is no insulation, producing cold spots.

This bag is not designed for sub-freezing temperatures and the temperature rating of 30 F -1C was considered optimistic but all the testers, who unanimously agreed that 35 F would be more accurate. In temperatures colder than 35 F additional layers were needed.

This bag is designed for the minimalist, ultra-light adventurer sleeping in mild temperatures. However, if you’re a hardy son of a gun, or willing to pull on some extra layers, then you could take this featherlite bag into temperatures well below freezing.
