My hands and feet are my weakest points when it comes to winter anything. I recently did a overnight camping trip where the temperature got to around 10 degrees F. The wind was blowing and my hands were getting colder and colder.
In my previous winter camping trips, I have tried varieties of gloves. Sometimes even wearing multiple layers of gloves. They all never truly kept my hands warm, I would always need a hand warmer slipped inside of them.
Well, except for this glove. Yes maybe its a mitten and not a glove but to me, this mitten is far superior in every way. You may not have the dexterity of a glove but that doesn't matter with this mitten. Because you can just take your hand out of this 'oven', do what you need to do, and then put the hand back in the mitten.
When I say 'oven' I really mean it, my hands were freezing from the 10 degree temps and wind. I put the mitten on and my hands were at a comfortably warm temperature in 2 minutes. If I needed to have fine finger skills, I just pulled my hand out, did what I needed to do, and then but my mitt back on.
Sizing was right for me, I may of actually ordered to big of a size. Mitten has good grip and I was able to grip a lot more than I expected.
So yeah, overall if you have issues with keeping your hands warm or are just going into extremely cold climates, buy these mittens. They are worth every penny
