Hothands save me every winter.

These Hothands are fantastic if you work in a job where you are subjected to cold conditions.  They stay hot for the time advertised and unopened packs last for several months.  Have been buying them for years and they never disappoint.

I bought these gloves 2 years ago. At that time they came in a 2 pack (2 pairs). I wear a size Women's medium winter glove so I bought medium in these as well. They are great. I use them constantly in the garden and for carrying cement pavers and bricks. The grip is excellent and I just hand wash them with a mild detergent and warm water to wash off the mud and just let them air dry. The one pair that I use all the time is just starting to wear out a little bit between the thumbs and fore finger. The finger tips are still perfect (that's where all of my gloves wear out first). They are also great for gripping my electric garden tools so I don't have to worry about them slipping out of my hands.

As a surveyor, I work outside year round. I stand behind a transit for 75% of my day. Turning dials and making adjustments as well as keeping field notes require at least three gloveless fingers. On the coldest days, my hands get so cold I can't even write. My fingers actually stop working. These gloves deliver as far as fit and dexterity. However, on cold windy days, my hands still get cold. I'd guess that anyone working inside, in unconditioned spaces would find them more than adequate. Perhaps even people working outside too if they move around a lot. I just needed something warmer. I still like them, and will continue to use them.

These are the best hand warmers that I have ever used. I'm 71 years old and have hunted in temperatures below zero. I hate wearing gloves on my shooting hand, so I keep my hand in my pocket with one of these hand warmers. I've been using these for about 5 years now. Never found any better. They do work for at least 10 or 12 hours. You'll never find me without them in the winter.

I received these as a free promotion. They are great as the weather cools down. I can work out in the yard, my hands are protected and warm and the grips are fantastic. Recommend!!

I use these to keep my hands warm in the harsh, unforgiving winters here in Texas. They do the job well. I like the style as well. They make good glove liners for ski gloves, too.

There is nothing better for people who are out in the bitter cold that gloves with "OutDry".  My son shovels snow from numerous commercial and condominiums - He called my after I had gifted him with a pair and said that his hands had never been so dry and warm.

These little grippers saved my life this past winter as we had one heck of a snowy/icy winter in Central Oregon.  I wear a size 9 women's boot. The large size fit snuggly, no worry of them falling off.  If I had a large man's size foot, they might be a challenge to get on.  One of the things I love the most about these is that they are only on the toes.  I can walk into grocery stores with them without worry of slipping around because I still have an exposed heel.  I am forever forgetting my keys or grocery list on my kitchen island, I LOVE that I can walk on my heels with these grippers across my wooden floor to retrieve my forgotten items.  I have Osteroporosis and have had a hip replacement. Needless to say, I can not risk falling.  I never slipped once all winter!  These are marvelous!  I LOVE them so much I bought several pair to hand out as Christmas gifts to my friends and family.  Leave it to the Norwegian's to get it right.  They certainly know the snow/ice.

I use these in the northern Wisconsin winters to keep my hands warm and dry. Especially great when I am snow blowing.

These are my daily drivers for snowboarding in Colorado. They always keep my hands toasty warm, even on the top of mountain peaks and below zero weather.

My hands tend to get cold, and these keep my hands warm while letting me do handwork while keeping them warm. WARNING: IF YOU ARE ALLERGIC TO WOOL, THESE WILL ITCH.

I absolutely love these gloves. They are perfect for Michigan winters. I don't keep these away from the snow or water, so yes the material doesn't look as good anymore, but my fingers are happy!

I work outside and one of the best gloves I've used for winter.  Truly keeps your hands warm, and there cozy.

These were amazing! I was in 18 degree weather and my hands stayed warm and they are so grippy. They aren't massive so they don't really get in the way. I highly recommend these gloves. I even used them for making a snow man for my 3year old nephew and they were a life saver.

During the winter months, I continue my daily walks outside.  These gloves are just what I needed to keep my fingertips warm.

I have 2 sets of these to go in my Venture heat gloves.  I have Reynauds, so my hands are cold almost all the time.  These are a lifesaver.  I keep a pair in my handbag at all times, so I can put them on at anytime needed, which might be in an air conditioned room, an under heated room, or even if I have to pick up something cold.  I wouldn't be without them!

Got these for biking in the winter. I've been through lots of different brands and models, and these are by far the best.

The single free finger makes them dextrous enough for shifting, braking, locking & unlocking chains, etc. The three joined fingers are very warm. They are wind and water-proof and have a long enough gauntlet to prevent cold wrists. You can tell the Outdoor Research design team put a lot of effort into these and I congratulate them.

They're kinda ugly, and I can't flip the bird at all. Otherwise, these are a best buy.

Bottom-line: serious cold-weather performance without sacrificing dexterity.
