TerraTherm Hand Warmers, Pocket Hand Warmer - 5, 10 or 30 Pairs - for 12 hours of warm hands, Hand Heat Pads activated by air, 100% natural warmth, Pocket Heater

Just been to Disneyland Paris and there was a wind chill which made it feel cold. The kids had these and they worked incredibly well and lasted 10 plus ours. That’s all we needed them for, they were still warm when we got back to the hotel. They do take 10-15 minutes to start working but then they get warmer and warmer as the day goes on.

Shove them into a backpack or glove compartment and forget about them unitl you need them. Produces good heat in about 10-15 minutes, which then lasts for about 8 to 10 hours. A good product.

These do what they say on the package, but three things spoil them: 1. They bunch up inside your gloves.2. They can drop out of the glove and get lost. 3. They don't keep your fingers warm. Otherwise they're fine, and the heat lasts many hours. Useful to keep in the car, if you can see well enough in the dark how to open the packet. When all goes well they are very useful.

Great productStay warm for hours and hours

I bought these in preparation for a city break where I knew it would be cold.I found they did a great job of keeping my fingers warm. I put them in my pockets and just held them while my hands were in my pockets as I walked around.I even slid a pair into my shoes to keep my toes warm!They continue to provide a source of heat for many hours.I expected them to be practically stone cold before the advertised 12 hours, but they still gave off enough heat at around the 12 hour mark to prevent my fingers from getting cold.

We are up at 5am for work.Open the packet when you get up.Toasty for when you are ready to leave the house 45 mins later. . Perfect when I am playing winter golf

These last for an impressive amount of time, however I do wish they were just a bit warmer. When my hands are particularly cold they don't feel hot enough. Take about 5-10 mins to get going but once they're up to temperature they last for 10+ hours.

Love these - great value.
