Psolar BX balaclava

PsolarLuke, I am your father. This Darth Vader looking setup is a basic medium-weight Polartec fleece balaclava with a unique feature: the mouth opening is covered by a little heat exchanger thingy.

The thingy purports to store warmth from your exhaled breath and use it to warm incoming air. Benefits of the thingy are that it warms your core and humidifies somewhat. I used it last winter on some below-zero cold trips, including Denali. It seemed to work, but I’ll be the first to admit that I could be imagining.

It does impart a "taste" to the air you breathe that some people might find off-putting, and some might find it claustrophobic because of the thingy covering the mouth. Bottom line: no scientific but lots of anecdotal evidence that it works; but then, there’s lots of anecdotal evidence for alien abductions too. Sorry, you’ll just have to try this one yourself. The good news is it’s a high-quality ‘clava and the thingy is removable.

  1. We are the manufacturer and we do have scientific evidence. Look at the June issue of Chest for a published scientific study. Also, you can simply wash the mask in a washing machine to eliminate any odors. More info on these issues can be found on our FAQ page at
