Patagonia Down Sleeping Bag – Tested

Waking up at 4am in the Beartooths early April with Beau Fredlund, Kt Miller, and Nick Webb. I rolled the dice and brought the Patagonia 30* Down Bag bag with a floor-less mega-mid.

Finding the right sleeping kit in the Cascades has always been a process of comparing functionality, safety, and weight. I’ve sacrificed the conservative choice of synthetic safety countless times in the name of lightweight and packability, and have mostly gotten away with it (knock on wood). I’ve also been a big fan of looking at your whole kit when you’re in the backcountry. For example, your insulating jacket, base layers, and sleeping bag all work together to keep you comfortable and safe in the mountains.

I will admit, I have become a fan of Patagonia’s products over the years, especially their backcountry touring line. When I heard about their 850-fill down sleeping bag line coming to the market, I knew I had to give it a test to see how it compared to other bags I’ve been using.

This spring and summer, I’ve been testing Patagonia’s 30 degree down sleeping bag. There are three different bags in the line-up, and this is the warmer and lighter of the fully functioning bags. I am definitely intrigued by the hybrid bag inspired by Steve House, but we’ll have to save that for another review. I’ve gambled and taken the lightweight down bag on several spring ski trips (that ended in very snowy conditions) and several mid-summer mountaineering trips, including a recent trip up Mt. Rainier. Overall, I am impressed and have found a go-to bag for most mild weather trips.

I was initially impressed by the lightweight fabric used for the shell, and the lightly textured fabric used to line the inside. The liner fabric is the same material Patagonia uses on their Houdini jackets, but seems to have more texture to it. This 15-denier nylon fabric is comfortable, and does not stick to you when you get inside, or if you sweat a bit during the night. I normally can’t stand being barefoot inside of a nylon sleeping bag, but the liner fabric on this bag makes that feasible (in case you also have a problem with sleeping with socks on).

The bright orange color of the liner gives off the feeling of warmth, which serves as important psychological protection after you made the decision to take a 30* bag instead of a 0* on your April skiing trip in Northeastern Yellowstone. The outside is made of a 15-denier Pertex Quantum fabric, which is durable and coated with a DWR finish to ever-so-slightly ease the stress of wet weather on your coveted down bag. I’ve found both fabrics to be durable, and lightweight.

Note the baffle construction in the main body and the difference in the toe box. This feature, combined with the half center zip make for a unique sleeping bag with a number of quality features.

Most of us know that Patagonia makes a strong effort to source quality products that align with their mission and values. The 850-fill down is quality and provides adequate warmth for the variety of conditions I have tested it in. On the multiple spring ski trips, both in the Beartooths of Montana and the Sierra Nevada of California I was comfortable with this sleeping bag in combination with a Das Parka and capilene thermal long underwear. The temps on both trips dropped into the high teens, and we used a floor-less mega-mid as a shelter.

The baffle construction is adequate for this bag, but is not as technical as their warmer 19* version. The baffles are stitched through to cut down on weight, but this can cause cold spots between baffles. I have not had a problem with this once the bag is lofted after being removed from the stuff sack. I’ll be curious to see how this holds up over time.

Similarly the toe box construction is different than any other sleeping bag I have used. The toe box is fully baffled and has re-oriented the baffles to provide more space and to match the shape of your feet. I have had mixed feelings on this, which may be due to how I sleep. I’m generally a side sleeper, which means my feet are rotated and not matching how the toe box was designed. During the coldest nights in the snow this spring, I found my feet getting cold towards the end of the night. Full disclosure, the temps were well below what the bag is rated for. Nothing a hot water bottle didn’t solve.

The center half-zip is a feature that has grown on me. It cuts down on weight and is easy enough to access. I especially like the bottom zip option for clipping into an anchor, or just using your hands while keeping the bag zipped all the way up at your face for comfort. My only qualm would be the incompatibility with zipping two bags together in the case of a cold emergency (but that may be my WFR instructor-brain coming out).

The stuff sack gets the bag down pretty small. A compression sack could squeeze out some of the mass, but over a long time it may compromise the insulation structure.

Overall, I am impressed with Patagonia’s Down Sleeping bag. The 30* bag weighs in at 830 grams (for a regular size), and packs down well. It does not come with a compression sack, which would allow you to get the bag a bit smaller, but would also likely compromise the structure of the feathers over time. I’d highly recommend this option for more moderate temps and in combination with insulating layers for colder missions where you want a lightweight kit. This bag can handle it!

   Good review Jonathan.Tabitha and I have been using these bags this summer with about 25 nights in them mainly backpacking. Super nice and light. The middle zipper works well for my wife, but it’s more a wrestling match for me but I’m still working on the right move to get in and out. Really like the way it cinches around your head. We use liners as we have with all our down bags of the past. Not sure if you could compress it much more than the stuff sack it come with, but they do give you a big storage bag for home storage. Lofts nicely. We spent three nights in rain in the Wrangells with mid 40’s at night and they worked great, but you have to be obsessed about keeping them dry.

   Our previous downbags were the “lightest” when we bought them 15 years ago. These are each a pound lighter, but a wee-bit bulkier.
