I carry chemical warmers in my first aid kit for cold weather climbing, hiking, and camping excursions. But I only buy the toe warmers, not the hand warmers. Here's why.

When we are out climbing, hiking, or camping in cold temperatures, we need to layer well. And our layers need space between them to insulate. That means our liner gloves need to strike a balance between cold protection and being thin enough to work with your outer gloves, too.

Ice climbing usually demands a lot of different gloves. Different portions of ice climbing need more dexterity and therefore less insulation. Some portions are the opposite. Some portions expose your hands to a lot of water. The full video shows how the approach ice climbers use to pick gloves to bring can help us think through how different gloves, in combination, can help us ensure our kids have warm hands on their climbing, hiking, and camping adventures in winter.
