Two part question (or 3). What type of mantle does this use (is it a "stiff" pre-formed mantle)? I see no offering of replacement mantles....any ideas?

there a few youtube videos about how to change and preburn the mantles on this exact lantern. the mantles can be found at any camping store.

The Primus EasyLight lantern uses a Coleman #51 "slip-on" type mantle. It needs to be pre-burned on the burner post. Toward the end of the burn before the mantle gets stiff, open the valve & add a little gas to give it a rounder shape. Here's more information: http://www.backcountry.com/outdoorgear/Primus-Thorium-Free-Lantern-Mantles-3-pk/PMS0009M.html#answer_26370

I do not own it..but from what I have read here, and elsewhere..it is a mantle-less lantern. I was wrong. I just watched a video showing the replacement of them. I thought they were mantless lanterns, but unfortunately not.######################Actually it does have a mantle, if you check out www.primuscamping.com you can buy them there. Its not a stiff mantle, you pre-burn them just like you would with a Colman.
