Thanks for this info. I will order some now. The Coleman mantles don't hold up to off road activity, especially washboard roads. Perhaps the Peerless will.
The Peerless do hold up. I did 2 weeks last year in Southern Utah with 3 lanterns and not a single broken mantle the entire trip. It is possible to break them, of course, but they are cheaper and waaaay better than the Coleman variety. They will change your mind about lanterns with mantles.
