Climbing Extreme

According to manufacturer N-rit heat pads provide up to 20 hours of warmth, the average temperature being 60 degrees in Celsius. Pads are odorless, non toxic and disposable. The extra plus on these is the fact that pads can be put back in to reseal able outer packaging, which stops the warmth. As a result they can be used on multiple occasions

Pads warm up within few minutes; one just needs to shake the pad to get it going. This being said you should prepare the pads before you’re freezing. Those few minutes are very long if you are. I can tell.

I’ve used these inside my gloves. They were an excellent aid while climbing in very low (around -30 in Celsius) temperatures. Problem with these pads is the size, they’re a bit difficult to place inside the glove unless there’s large enough integrated heat pad compartment there. In addition to gloves, these can be used inside sleeping bags, jackets, or for instance to warm up electronic equipment for prolonged usage.

I bought my pads from Kärkkäinen, Oulu, Finland. Price was around 2 euros. This being said, I’m sure that any well equiped sports store will sell these or something similar.
