Culling winter camping stuff. This has a copper heat exchanger that you breath through. This only works for stationary activities (hunting/fishing) or sleeping - for those it keeps you a lot warmer.

This is like new = $15. Paypal, check, or cash

I'll be at the Midwest Expo on Saturday morning-mid afternoon.

Otherwise shipping $10. Going to post a bunch of other stuff too, per item shipping reduced if you want a few things (I only want to break even on the usps costs)

Email sent regarding both masks.
