Hand feet warmers that work at high altitude?

post #1 of 9
Thread Starter 

I bought a box of "hot hands" only to find them useless at high altitude (or maybe I just some duds?).

 

But since chemical hand-warmers use oxygen, it stands to reason that just like anything that uses O2 their performance diminishes at 10Kft.

 

Are they alternatives?  My wife has circulation issues with her hands and feet, so dressing warmer doesn't really help much.

Electric socks and gloves.

You have to look at the expiration date on those handwarmer packages.

I am thinking you got duds.  That is the exact brand I use and they seem to work fine.

I just checked the used by date and it's 02/15/2016.  They were bought back in Oct 2012.  They didn't work then and they don't now.  Guess they were duds.

Regardless of expiration date, I consider them suspect if I bought them the previous season. I used a few last weekend, and some worked, some never fired; the ones that worked only lasted 2-3 hours.

Consider getting heated gloves and socks or footbed heaters. 

 

I have Hotronics installed in my footbeds and never have cold feet. 

I demo'd Fired Up Gloves and liked them for warmth but they have a few fit issues.  Hestra makes a heated glove that I sell in the store where I work and its very well received.   I'd look into these options for someone with consistently cold feet or hands.

I'll tag a few on the side of the page.

there are known issues with certain foot/hand heaters manufactured in China. I would contact the brand to see if there are any other complaints or try a brand new pack from a different lot or year.  

 

I just tried on some LENZ gloves on the other day and although I didn't take them into cold weather, they were pretty impressive.  Heated up fast to very warm and were very comfortable.  I couldn't tell there were any wires or elements in them.  Pricey but if you really have cold hands worth it.  They also make a heated sock that was quite thin.

I'm considering a pair of heated glove liners.  Anyone have any experience with them?

I was just going to post a link to this site.  They have quite an array of heated products.
