## Description

Product Description The Ergodyne N-Ferno 6970 Extreme Balaclava with Hot Rox is a technologically advanced high-performance cold weather mask to combat the damaging effects of breathing in cold air. Warm 320g fleece covers the face, neck and head, while controlling moisture to keep you dry and warm. The built-in, removable heat exchanger warms the air before it gets to your face for easier breathing in extreme cold. The adjustable nose clip prevents eyewear from fogging, and the adjustable face mask is removable with hook-and-loop attachments. Reflective accents offer visibility at night or in low-light conditions. Patented design. One size fits most and can be worn alone or under hard hats, ski helmets or other head protection. This winter face mask is perfect for those who work in construction, freight/baggage, drilling/mining, oil/gas refining, iron/steel, delivery/service, landscaping/grounds, warehousing, and working in refrigerated areas. Can also be worn as a ski face mask or worn hunting, climbing, running, cycling, boating, skating or other outdoor sports. From the Manufacturer The N-Ferno Extreme Series doesn't give a rat's rear end how bad the Ice Age wants to freeze your hot-blooded heart. It offers 3-layer, noggin lovin', heart warmin' performance to keep you comfy when Old Lady Nature is bringing her worst. N-Ferno Warming Products include winter liners and other head wear designed to keep workers warm and comfortable. We've got versions for cool, cold, and extreme conditions with hi-tech fabrics and superior features for reliable warmth from ear-to-ear. In fact, most liners have pockets next to the ears to hold warming packs.

Review: Works great but drips condensed moisture - I bought this to wear while riding my bike in the winter. If the temperature is 20 F or above I wear a regular balaclava but when the temperature drops below 20 F, I wanted something warmer. The heat exchanger works wonders. I used this today when the air temperature was -9 F (-28 F with the wind chill index). I wore ski goggles over the top of the N-Ferno 6970 and I tucked the neck of the balaclava into my ski jacket. With this combination of gear, I did not have any exposed skin and I could both see and breath just fine. While riding my bike I was exerting a lot of energy and breathing heavy at times (going up inclines). The heat exchanger warmed and humidified the air so my lungs never felt like they were getting blasted with cold air (the weather advisory on the radio was warning people to not breath deeply and to minimize talking if they had to be outside today). The ONLY thing I didn't like was that some of the moisture from my breath was condensing and dripping from the mask. That is a really minor problem and I don't think there is any way to avoid it. I would HIGHLY recommend this mask to anyone who rides or works outside in extreme cold.
Review: Works very well with glasses and ski goggles - Fine with my glasses. you can bend the nose area for a better seal. I found that the key is to pull the balaclava portion over my nose, not leave it under the chin, then attach the exchanger, which by the way, can attach to other balaclavas. My glasses did not fog up. I also tried it with my Over-The-Glasses ski goggles and it worked fine. Typically, my regular glasses fog up before the OTG goggles do, but they never did with the N-Ferno.. I tested the N-Ferno 6970 Extreme Balaclava in 23 degree weather with 40-45 mph winds with no hat. In those conditions, my head got a bit cold, but my face and ears were toasty. I would wear it with a ski hat or helmet in the future. Overall, it is the best "heat-moisture" exchanger balaclava I have used, and I have a couple other types in my outdoor clothing arsenal.

## Questions & Answers

**Q: Where does the moisture in your breath go? Does it drip on to you?**
A: I never had any moisture drip on me.  The face cover is removable and partially rigid.  It sets slightly away from your nose and mouth so moisture does not really collect anywhere.  The sides of the face cover are cloth with some Velcro to fix it to the hood.  I convoyed for an hour and 30 minutes while exposed out of the hatch of a track vehicle in South Korea this past December.  The hood did an awesome job and didn't fog my goggles.

**Q: I have a 7 3/4 hat size.  Is this large enough to be comfortable?
Thanks**
A: Yes it is. I'm a 7 1/4 & still have plenty of room & its comfortable. Plus the face mask is fully adjustable so you won't have any problems.

**Q: does it keep you from breathing in cold air?**
A: Don't think so, but I returned mine because it was too small. Wasn't cold enough last fall to test. Good luck.

**Q: Anyone have suggestions for cleaning the face mask?**
A: I use the wipes that you clean your hands with.

### ⭐⭐⭐⭐ Almost the Perfect Balaclava
*by A***2 on December 28, 2015*

Typically I have the following problems with Balaclava: 1. In the cold the moisture of my breath will freeze and cause the area around my mouth to be incredibly cold. 2. They have limited options as to what parts of your face they cover. 3. They cause me to fog up my goggles when I try to cover my nose as well. While the sponge area surrounding your mouth will get wet, it didn't cause me any trouble whatsoever and the fact that it protrudes a bit meant that the cold/wet parts were never actually touching my skin. While it does get a little cold around the mouth and nose, it was always significantly warmer than the outside and actually was nice as the rest of my head was pretty warm. The ability to take on and off the mouth mask was great and I often took one side off and skied down. It is not easy to access (especially to put on again) when you have a helmet on but it is good enough. The moth mask isn't an amazing fit but it was good enough and did not hurt my nose at all. Depending on how you place your goggles they will fog up, but there is definitely a way to do it where they don't. Because the sponge allows you to breath in and out normally, most of the heat from your breath will exit to the atmosphere instead of going into the goggles and fogging them up. Overall, would highly recommend this.
