Grzejki Chemical Feet Warmer - 10 pairs

The heaters performed excellently during harsh winter conditions in the war in Ukraine. Their operating time may depend on the batch, but they always lasted at least 4 hours. They are definitely better than those made in Ukraine.

Together with body warmers, these are a must-have during cold days. Last winter I had to walk in the snow wearing summer shoes – these insoles really provide comfort and protect against freezing.

They work very well at night outdoors, when it’s cold or the wind blows hard. It's important not to stick them directly to the skin.

Chemical warmers work perfectly for winter activities or outdoor work. I recommend them because they work problem-free and heat for a long time.

Grzejki chemical foot warmers work just as effectively as other warmers. It's worth having them on hand on cold days – they can improve your mood.

They heat strongly at first, so you can even feel a burning sensation in your fingers, after a dozen minutes the heat evens out, but the fingers still stay warm. They work for several hours and are useful in pockets, gloves, socks, and even in a hat. I recommend them for short winter outings.

A compact and cheap warmer. Thanks to its small size, you can always have it with you – in a bum bag or backpack. Small but improves thermal comfort.

The warmers literally saved me from freezing while sleeping in the forest at -10 degrees. I stuck them on my blouse under the armpits, on the chest and inner thighs – they worked quickly, at first they were too hot, then it was pleasant. The downside is the short working time (2-3 hours), but at such low temperatures, it's understandable. They don't work in shoes due to lack of air access. I used quite a lot that night, but still recommend – better than hypothermia!

A great option for winter walks in the city and tourist trips. They heat for several hours, you can feel the warmth after a moment, but they are not too hot. The glue holds the warmers in place in the shoe very well, and later they are easy to remove.

They heat perfectly, irreplaceable during trips or cold days at home. They even helped me while working on the computer when my fingers were cold. I give four stars because the temperature may vary depending on use – they may be less warm in shoes and on open air you can burn yourself if you’re not careful. Maybe gel warmers work better in such conditions, but I still recommend these.

The product matches the description – it keeps the temperature in the range stated by the manufacturer. I haven't tested them outdoors yet, it's just a pity you can't buy them in larger packs.

This is essential equipment for any soldier or anyone hiking in the mountains. Very practical, they help in tough cold conditions. Ordering and delivery were hassle-free, I recommend Militaria.pl as a reliable company.

I bought it for the second time, the product meets my expectations. Very useful when the weather is unfavourable and it is easy for your feet to get cold. I highly recommend both the product and the Militaria shop.

They heat for a long time and effectively, you can recommend them without worries. The glue holds stably, so the insole does not move inside the shoe. The temperature is appropriate – they are perfect for walks in the forest or cold days.

For autumn-winter weather, this is essential kit for those staying outdoors. I bought it because of the bulk packaging, although I think those with the penguin heat up better – I'll check that yet. Regardless, I definitely recommend the product.
