While Patagonia has made a wide variety of low insulating products for years, they had never made a sleeping bag Until now.
I was very excited when I saw the Hybrid Sleeping Bag simply named because I had been considering switching to an elephant foot system like a hybrid for a while but I stopped because of the Disadvantages that we noted during our review of the Brooks Elephant Foot range. The Patagonia Hybrid Sleeping Bag solves the worst of these problems and, at this point, if I could only own a sleeping bag for everything I do in the mountains, all year round I would choose the Hybrid.
Why is there only half a sleeping bag?
The first thing you will notice about the hybrid half sleeping bag is that the upper half is simply a thin and uninsulated shell, while the lower half is the typically cracked, well padded and insulated bag. Basically, the hybrid builds on the idea that if you already bring an insulating layer to your upper body, this part of the sleeping bag is redundant, and it’s just an unnecessary weight you’re carrying around the hills. Thus, the hybrid is designed to work in conjunction with a belay jacket – the bag isolates your legs, straddles with the belay jacket around your waist, and the fine upper shell of the hybrid helps keep everything in place.

In addition to reducing your overall weight, the modular nature of the hybrid allows it to be adaptable to some extent under varying conditions. During this review, I used the hybrid with (a) just one base layer at the top, (b) with the Patagonia Stretch Nano Storm at the top, and (c) combined with a full boot jacket, all Depending on the outside temperature.
Patagonia does not give a standardized isolation index for the hybrid, but cites numbers around 10 to 15 ° F as low. Although I was not able to use the hybrid at cold temperatures, I used it under conditions below freezing, and I did not experience cold feet, although I only wear one Base layer and pants with socks and not booties.
So far, the temperature limiting factor has definitely been all I wear on top, and once I’ve added a layer on the upper body, I was very hot and I slept well . I will however update, once I had the hybrid in really cold conditions.
Weight / Packaging
This is where the hybrid really excels. At only 18 oz, it is lighter than any other 15 ° bags, except for Ultralight quilts and the Brooks Range elephant foot. There are other bags that have a weight similar to that of Feathered Friends Vireo and Vireo UL, but they are rated for much warmer temperatures.
Of course, the amount of weight savings you actually get depends on the jacket with which you associate it, and whether you will wear this jacket anyway. For example, when I associate it with my Mountain Mountain Belay Parka, my total weight for the bag and jacket sits just around three pounds. This is comparable to several other 15 ° bags on the market.
The hybrid packs have a diameter of about 11 “long by 6”, which is much smaller than the most complete bags of 15 ° and is competitive with many summer bags. But again, you need to consider the size of your jacket, unless you already train it.
At $ 299, the hybrid is not cheap. But it is competitive or less expensive than most other bags with a similar temperature index, while being much smaller and more packed. It’s cheaper than Brooks Range Elephant Foot and, in my opinion, its hood is infinitely more practical than the elephant foot straps.
However, you should consider the price of a belay jacket at the overall price of your sleeping system. If you do not already own one, you are considering a large investment.
And this point is really true with all aspects of the hybrid bag. If you already own – and usually – an appropriate jacket insulated on your missions, then the hybrid is lighter, smaller, cheaper and more adaptable than a traditional sleeping bag. However, if you only find your sleeping and travel insulation system, the half bag may not be the simplest choice.
The first incursion of Patagonia half sleeping bags is impressive. The top shell of the new Hybrid Half Sleeping Bag makes it a very good option for quick and light lenses, where a light package and a minimalist bivouac are required. But its modular design also makes it one of the most versatile bags on the market for year-round use.
