YMMV Review

Most people here in the states have probably not heard of Berghaus. Berghaus is a UK company that has been around since 1966. Started to address the lack of quality outdoor gear options. Since then it has grown into a brand with a full range of high-quality gear. This gear is used all around the world by professional and recreationalists. I have always been drawn to the European companies. They generally have intriguing color combinations and a trimmer fit than most American brands. I was excited when they were willing to send me this for a test. Thank you Berghaus for giving me the opportunity.

I tested the down jacket on a variety of trips and activities. I used it on a two day camping and fishing trip, as a midlayer for snowshoeing, and wore it around on plenty of cold nights. It got tested in a little rain, but for the most part, it has been dry.

The Furnace Jacket is a lightweight down jacket aimed at giving you warmth and weatherproofing in a minimal package. At the heart of the Furnace is the down insulation. It uses 700-fill goose down insulation to provide warmth. Down is very warm for its light weight making it an ideal insulator. It also can pack down small, which makes it even more ideal for trips when you have to carry everything on your back. Down fill is rated by its lofting capability and the higher number the higher the quality. At 700-fill this is high quality down, only slightly lower than the best. For more information about down as an insulator, all the pros and cons, and more information then you probably want; take a look at my knowledge base article by clicking on the link below.

Down is not without its kryptonite. This is water, which can render the down completely ineffective as an insulator. Down does not insulate when wet. To combat this, the Furnace Jacket uses lightweight nylon PERTEX for the outer shell. PERTEX Microlight is made of tightly woven yarns. It is both downproof and windproof, water-repellant and durable. It is not totally waterproof as the seams have not been taped, but it will hold up to a light shower and snow. The dense weave will also keep you slightly warmer as it keeps the warmer air in. Due to the baffled construction and stitched through seems, the jacket is vulnerable in these locations. The Furnace Jacket has articulated sleeves to give you good freedom of movement even with the padded insulation. They have also made the fit slightly adjustable with an elastized hem drawcord that can be adjusted to your fit preference. This is good for keeping cold winds from up from below. At the wrists, they have kept it simple. There is an elastized cuff that will stretch when getting the jacket on and off but still keep the wrist tight and low profile when in use. As a midlayer it is important to not be too bulky as occasionally you may want to layer over it with a weatherproof jacket.

The Furnace has two hand warmer pockets that are zippered and an internal zippered chest pocket. The internal pocket surprisingly does not have an audio out which I found to be a strange omission. The jacket has been made with a drop tail in the back for extra coverage. It has a fairly standard shape with a medium height collar. The jacket can be compressed and packed very small. It comes with an included stuff sack that can be used to pack the jacket. Since down is a sustainable material and PERTEX is taking steps to minimize their impact on the environment, I gave the Furnace Jacket a good rating for sustainability.

The Berghaus Furnace Jacket had me really excited to test. I like to review the European brands as they generally have a trimmer fit compared to typical American sizing. I am normally a size medium in American sizing and opted for a size medium in their sizing. I am glad I did as it fit me really well. The arms are comfortably long. I can reach out, and I do not have to worry about the arms pulling up. Where the fit is really good is through the torso. With a European fit, the torso is considerably trimmer than typical American sizing, and this is ideal for me. Through the chest, the Furnace fits exactly how I like it to. There is a just a little room underneath but not so much that I feel like I am swimming in it. There is a little more room in the stomach area, but since the jacket has an adjustable elastic hem you can tighten it up to your preferred fit. This is the best fitting insulated jacket I own. Even slightly better than my Arc’Teryx Jacket and that is saying something.

Wrist Cuff – Click to See Larger

At the wrist, the cuff stays snug with about an inch of room. It easily stretches to get on or off. I also really like how low profile the cuffs are. If you need to wear a shell over the top, you do not want to have the extra bulk at the wrists as it will impair movement. Speaking of movement, the arms have been designed with a slight bend to improve mobility. I never felt restricted by the jacket and really did not expect to. I am generally not too active with my down jacket on as I can get too warm. I did, however, use it for a morning of fishing on the Crooked River and had not problems casting with it on. I love wearing down jackets as they are just plain comfortable and the Furnace is no exception. The nylon inner liner feels nice and soft. Wearing it feels like you are in a cozy sleeping bag.

The Furnace Down Jacket is exactly that, a furnace. It packs a lot of warmth in a fairly low profile jacket. The jacket is easy to layer over the top of. Since it fits snug to the body, this makes it easier to layer over. The jacket has a good balance of breathability. You do not want it to be too breathable as it will let out all the warmth, but if it is not breathable at all, then you can overheat or get sweaty. The Furnace has a good balance to keep you both warm and still breathes. I had it out in several days around the freezing mark and was plenty comfortable. The outer shell is made of PERTEX Microlight. This is wind, down, and water resistant. On windy days, I did not have any issues with it penetrating the jacket. I even had the jacket out in a couple of different rain showers, which is generally a no-no for down jackets. With the PERTEX shell, the water just beaded up and rolled off. None of these were too strong or too long and rain will eventually penetrate at the seams if it rains enough. One thing I generally get annoyed with on down jackets is when they lose lots of feathers. This is where a down jacket can turn from just okay to great. I have to say that the Furnace Jacket loses hardly a feather. This makes it so I want to wear it both in the mountains and just around town. I do not have to worry about having feathers all over my clothing.

Stuffed in the Sack – Click to See Larger

One of the benefits of this jacket is just how packable it is. It compresses really small and can be stuffed into small spaces in a backpack. I really like the pocket set up on the jacket. There are two hand warmer pockets and one inner chest pocket. The chest pocket is great for putting electronics into. The only thing that is missing is an audio out. You can still just have you wire come out the top of the pocket with the zipper just pulled down a little. All the zippers work well and having a draft flap behind the zipper helps keep in the warmth. The soft chin guard is also a plus on the flap as it protects from irritation. So far, in all my testing the jacket has held up well. I have not seen any wear or tear yet.

Overall ★★★★☆

Overall, I have really liked the Berghaus Furnace Jacket. There are plenty of down jackets that are insulated with high quality down but not all of them fit as well as the Furnace does. This jacket fits me just right. It is close to the body but not overly snug. By being close to the body it is easy to layer over which is important for a midlayer. Here in Bend I normally do not have to worry about wearing a shell but in the mountains that is a different story. With the PERTEX Microlight outer shell if you do get caught out the jacket can handle it. One thing I did not mention above is the jacket also looks really good. The colors pop but are not over the top. I get a lot of compliments when I wear it around town. I really do not have any big negatives with this jacket. The Berghaus Furnace Jacket retails for about $212; I had to convert it from British Pounds. They are a challenge to get as there are not a lot of retailers in the states but worth it if you can get one. As always, your mileage may vary.
