Works great even in extreme cold

I had one of the other cheaper varieties of jumpers for my Harley.
It worked pretty well in LA but when I moved to NYC things couldn't crank the bike at all.

This jumper works great even in the bitter NYC cold. Turns the bike on in one easy go.
I would definitely recommend this over anything else you'll see here.

It doesn't have the little bells and whistles but does what it's supposed to flawlessly.

I have had this for months now and it is great. In the cold temps it turns off but we're talkin 20 below zero. I think any electronic would have some issues. Other than that I keep it plugged in at all times period is super convenient.

I went a full winter not knowing this existed until I found it in REI, it snaps on in seconds & prevents your water from freezing on those really long & cold hikes. I used it this winter & it was amazing. Worked perfectly. CamelBak Antidote Insulated Tube. I used it during my Iceland expedition as well.

This thing works, even in sub-zero temperatures when it's been stored outside in the cold. Quick charging, it's got a very durable case, heavy, durable cables, strong, but easy-to-squeeze clamps. And it's easy to carry and lift up onto our big truck's fender, even for a petite woman like me.  Wonderful product.

I wore these on a trip to grand canyon where temp was around 15 to 20f. These get the job done. The padding is very thick and provide excellent insulation. I always love this brand. Highly recommended for extreme cold conditions.

I was not prepared for my first Alaskan winter. My poor leather jacket, though thick and heavy, did not have the insulation to keep me toasty when temps started dropping below 0. It was hard coughing up the money for this coat, but I'm glad I did. I can throw this on over a t-shirt and walk outside on a -10 degree morning and barely feel a chill.
I've had it for a month so far and it hasn't let me down yet. I definitely recommend it.

I charged it up and it's work like a champ every time.  I have used it to jump a car with a (possible) dead battery about 4 times and it never hesitated.  And it's been extremely cold here.

Living in Florida I didn't think I would have much use for this.  I purchased this ski mask for the few days it gets cold in the winter.  My primary mode of transportation is a scooter and I wear a 3/4 helmet so I wanted to keep the wind off my neck.  Wouldn't you know it, just a couple of days after the ski mask arrived and we had a cold snap.  When I headed to work it was only 30 degrees out, and I was driving at about 70 MPH down I-75.  Although I felt the wind pushing on the mask, I was never cold.

The advertisement states that it is helmet friendly, and I can attest to that.  The helmet I have normally is snug, and there was no problem putting it on while I was wearing this mask.  It was also really easy to pull down around my neck when I went into my bank; don't want to cause the tellers to reach for the panic button.  Pulling it back up and on my head was just as quick as pulling it down.

My only complaint I have is that I didn't buy this years ago.

The material reminds me of Under Armour but it isn't if that makes sense.  Does the trick on those cold days when working outside or going for a walk.  We don't get much snow but I can easily see how this thing would be great on it.  Does a good job of blocking the wind and keeping the warmth in so I would recommend this.  We don't get very cold weather, below freezing is not common and below 0 is rare so o can not tell you how well this works in freezing weather but for above freezing this things is a great addition to any outdoor setup.

I was giving a discount to test and review this mask and I gave it 5 stars based on performance.  If we do get women cold weather and this thing isn't as good as it seems, I will do an update.

Works better than expected!  I thought maybe since this isn't Under Armour that it would be some cheap product, but no.  Keeps me extremely warm, and works just as good if not better than Under Armour!

Always works, even in sub zero temperatures. I even tried it overseas in the UK and it worked.
The support is also outstanding

Excellent heavy duty hose that stays flexible in the cold

At first I was a little concerned at the price as it seemed high. But I coupled this with a sealed-lead acid battery and a solar panel to keep it all charged and this has work better than I expected. It has been a very cold and snowy winter and every day, without fail, the door has opened as expect and closed as expected, saving me the need to go out into the cold every morning and evening. It is well work the cost.

I was afraid it would keep blowing off and it does. Otherwise it works great even putting it off and on at 8 degrees Fahrenheit. It was stiff in the cold.. Material was a little thinner than I expected but is durable.
