Chris Richards reviewed it in today's Washington Post, as follows:

Nickel Cooling Deodorant

You'll find my new deodorant in the fridge: top shelf, between the peanut butter and the Grey Poupon.

That's because Nickel's Cold Sweat deodorant is meant to be refrigerated.

Very cool! (Ba-dum-bum.)

But it's not a gimmick.

This translucent stick boasts a clean, crisp scent that feels incredibly refreshing — kind of like mouthwash for your armpits.

With winter settling in there's no need to put Cold Sweat on the top of your shopping list, but come the dog days of July, this deodorant's chilly jolt and long-lasting protection will be worth the daily walk from the bathroom to the kitchen.

From the product website:
