No, the ones i have are not waterproof. I am not sure if waterproof matches are strike anywhere.

Hi...

Unless they are waterproof (think Titanic!), they won't light...and even then, they probably won't work.

When it comes to matches...ALL matches will deteriorate over time.

According to people who know a lot more than I do about matches...if you MUST use them in the outdoors...the best ones to have are REI's Stormproof matches.

Carrying secondary ways to light a fire is encouraged.

I keep a Bic in my pocket summer, winter, spring and fall.
Want waterproof (?) matches? Dip them in melted paraffin and store them in an airtight container.
BTW! A wet Bic won't work until you get it dried out! LOL
I don't know if matches are water "proof"? Water "resistant"? Maybe!

Anybody remember the coffee cans that opened with the "key" on the bottom of the can? The old timers stored their matches in those cans because they had a metal lids and rats and mice couldn't get to the matches. More than one house was torched by a rat/mouse gnawing on a match!

You can also coat match heads with nail polish, but today's strike anywhere matches are a vastly inferior substitute for the old ones that you could strike on your zipper, shoe sole or pop them lit with your thumbnail. You could put the old ones down the muzzle of a BB gun, shoot it into a brick wall and expect incendiary results when it hit. Fun for children!

I use redundant systems, I have lighters, strike anywhere matches, and water proof matches. I also have a mag fire starter block with cotton dryer lint soaked in petroleum jelly. I am kind of obsessed with fire starting.
