It’s no secret that sweaty, tired people are no fun to be around, and if these people are toddlers, all heck can not be far from breaking loose. Getting too hot under the collar can even be dangerous to your health, especially if you’re very young, old or performing physical activity.

When you’re outdoors, there’s usually not much you can do about the problem except drink plenty of water. Wouldn’t it be great if you could carry your own personal air conditioner around with you?

This is exactly what these scarf-sized towels are supposed to be. To use, simply wet one and wrap it around your neck; all the blood going to and from your brain passes through this part of the body, making it the best place to cool down rapidly if you’re starting to feel like you can’t breathe.

The secret to this miracle is that these garments consist of thin, perforated microfiber cloth instead of the terrycloth normal, fuzzy towels are made of. Their fine threads provide a greater surface area which leads to more rapid evaporation. Though it does not get as cold as an ice pack, the effect is definitely noticeable, and all that’s needed to refresh it is pouring a little more water on it.

When dry, they’re also quite useful as normal towels. The fabric they’re made of is pretty absorbent, soft and airdries very quickly, making them ideal for camping.

You can buy these as a set of four in different colors so siblings don’t have to share, each with its own carry pouch. They’re machine-washable and hypoallergenic (and therefore safe for baby). If you have to choose between a sun hat and this, take this: you can also wear one as a bandanna or hood if need be.
