No matter how warm your gloves are, sometimes your hands could use a little extra warmth. That often means reaching for a chemical hand warmer pack, something that does a great job – once. Wouldn’t it be nice if you could reuse those warmers?

With the Po Campo Reusable Handwarmers, apparently you can. Calling it a crystallization-type handwarmer, you activate the circular device by flexing the small disc inside to produce heat. Once warm, they claim it will stay warm for around 15-25 minutes. Obviously, this is a much shorter window than chemical hand warmers which can last for up to 10 hours, but for shorter rides the fact that they’re reusable could make them worthwhile.

To refresh the warmers, you have to boil them in a pot of water for at least 15 minutes. Po Campo claims they can be used up to 300 times.

Sold in a two pack with a carrying case, the hand warmers measure 3.875″ in diameter, and sell for $12.99 – currently on sale for $8.99.

    For our fellow Canadian friends, a company in Sherbrooke QC is doing something similar, smaller form factor. Look for Hot Poc 🙂

    If it’s too cold for gloves or lobster mitts, pull out the Pogies. They last a very long time. I’ve ridden in below zero conditions with regular gloves inside the Pogie and stayed warm for over an hour. With lobster mitts, Pogies extend that comfort for many hours.

    When you consider the energy req’d to recharge these, and the truly minimal run time — USB rechargeable gloves or disposable packs are better options.

    I know it’s more waste and packaging, but it should be noted that those disposable “chemical” hand warmers are basically iron powder, salt, water and sawdust and some charcoal. Not exactly uranium. The powder basically rusts very quickly when exposed to air with the salt.
